Ball Valves: A Long-Term, Cost-Effective Solution

From ipegstl.com

In the industrial world, valves are used to isolate or shut off systems. There are ball, gate, globe and plug valves, which are used for the majority of services. Other valve types, such as knife gate and pinch valves, have a much more specific application. For this discussion I will focus on the ball valve and why it is preferred.

Ball Valve Functionality

The ball valve is a simple device. It has a 90 degree operation and is easy to determine which position the valve is in: when the handle is cross line, the valve is closed; when the handle is in line, the valve is open. The 90 degree operation means there is no stem that rises and descends through rings of packing, which often drags whatever product is in the pipe up with the stem. The valve’s 90 degree operation allows for ease of automation with either electric or pneumatic actuators. Ball valves also have an inherent low pressure drop and offer bubble-tight shutoff. While primarily considered as on/off valves, ball valves can be used in throttling service by using coated balls and hard seats. Ball valves are also considered to be downstream sealing, as they utilize the system pressure to push the ball into the downstream seat to achieve their shutoff. There are exceptions to this, but generally this is the case.

Basic Ball Valve Designs

There are three basic ball valve designs . . .

What are Pressure/Vacuum Relief Valves (PVRV)?

From ipegstl.com

Pressure/vacuum relief valves are protection devices which are typically mounted on a nozzle opening on the top of a fixed roof atmospheric storage tank. Their primary purpose is to protect the tank against rupturing or imploding. Without an opening or a controlled opening, a fixed roof atmospheric tank would rupture under increasing pressure caused by pumping liquid into the tank or as a result of vapor pressure changes caused by severe thermal changes. Imploding, or the collapsing of a tank, occurs during the pumping out procedure or thermal changes. As the liquid level lowers, the vapor space pressure is reduced to below atmospheric pressure. This vacuum condition must be controlled by allowing atmospheric air to flow into the tank. In short, the tank needs to breathe in order to eliminate the possibility of rupturing or imploding. Because of its primary function, a pressure/vacuum valve is commonly referred to as a “breather valve.” . . .

TRIPLE R OIL CLEANING SYSTEMS: A COMPLETE SOLUTION

By Shane Takaki – Triple R America

THE ENGINEER’S COMPROMISE

Ask an engineer to design anything and the response will typically be, “You can have good, you can have fast, you can have cheap; pick two.”

When faced with the challenge of cleaning oil, Triple R’s engineers chose a design that’s good and economical, compromising on speed. Triple R’s bypass oil cleaning systems are designed to take a slow trickle of oil through a 114 mm medium, delivering perfectly clean oil: good and economical. In fact, with Triple R oil cleaning systems your oil can become cleaner than new.

There will be those who say that they already have filtration on their system and don’t need any more. The vast majority are owners of spin on, inline filters. The engineers of this type of filter made a different choice: they chose fast and cheap. These filters take 100% of the flow, so they do their work in one pass. The compromise is that it is impossible to clean efficiently so fast.

Take note that many of these inline filters come with incredible micron ratings. A rating of 1 micron absolute means that in a test environment, in a single pass, the largest particle that can pass through the filter is 1 micron. Note also that ISO has moved away from such tests because they do not reflect actual usage. To the end user, test results from a single pass are largely useless, so ISO developed beta testing, a multi-pass test that better reflects actual usage conditions. This is why Triple R espouses beta testing; it provides the user with information that is relevant to the customer’s needs.

INSTALLATION BY APPLICATION

There are three ways that Triple R oil cleaning systems can be installed. All are a kidney loop, returning to tank, but the oil cleaning systems differ to fit the applications. The most common installation is from a high pressure line in a hydraulics application. Triple R BU series housing tees off a working pressure line, often immediately after the pump, and returns to tank. This system incorporates a pressure compensated flow control valve to reduce the flow to a trickle. (An integrated check valve ensures that the pressure inside the housing stays within spec.) The oil flows slowly over the top of the filter element, down through 114 mm of medium to the bottom of the housing, where it returns to tank.

The second installation is in a low pressure system, such as engine lubrication. In an engine, oil from the pump goes through the oil gallery, is fed into the Triple R AL series housing, and again flows slowly from the top of the filter element down through 114 mm of medium to the bottom, where it returns to tank. This system does not require a flow control valve or a check valve and so is more economical.

Finally, we have systems that install completely offline, drawing from tank and returning to tank. These systems have their own pump and motor, making them completely independent of the equipment while cleaning the oil thoroughly and completely. Contamination never sleeps, and Triple R’s SE series of offline systems doesn’t either.

COMPREHENSIVE PRODUCT LINE

From its simple beginnings, the Triple R product line has grown to be able to accommodate all kinds of oil in a wide variety of applications. Our M series filter elements are commonly used in (high pressure) hydraulics applications where filtration requirements are very high. Our E series filter elements are recommended for (low pressure) engine applications where longer maintenance intervals and extending oil life are priorities. In applications where it is impractical to use system pressure to feed the oil cleaning system, Triple R offers a system complete with its own pump and motor.

Triple R complements our filtration technology with product families of vacuum dehydrators, centrifuges, magnet conveyors, oil separators, water separators and the Quicktron (an air bubble remover). With this complete product line, Triple R is able to meet all of your oil cleaning needs.

ENGINEERED SMC SPEED CONTROLLERS ENSURE PEAK PERFORMANCE

By Pete Amata

OTP Industrial Solutions supplies highly engineered pneumatic components for all types of industrial projects in industries such as automotive, food and beverage and OEM (original equipment manufacturing).

The basic goal of any machine design is to require that the machine work at its peak performance with precision and consistency. Speed controllers are an important part of this design. Speed controllers, or flow controls as they are also known, are a compact engineered component that normally provides “free flow” of air in one direction and “metered” air flow in the opposite direction. The “metered flow” is accomplished by using a check valve circuit to divert the fluid flow through a needle valve which can increase or decrease the rate of fluid as required. Speed controllers should be mounted directly to the actuator for immediate quick control of the actuator.

An essential rule of thumb in Fluid Power is, “when in doubt, meter out.” This phrase means that if you do not know the complete application circuit but need to control it, do it by regulating the fluid flow out of the actuator. This process will provide control by using the back pressure developed in the circuit to synchronize the speed and performance of the actuator so it does the work as required and under control. Whether you are talking about pneumatics or hydraulics, the principle is the same.

Vertical applications are known for being difficult to control. In a vertical application, the weight of the load can cause the cylinder to extend faster than the fluid is being directed to the cylinder; this causes erratic actuation with little or no force. The cylinder may also jerk at different times as the fluid catches up to the cylinder causing unstable performance. SMC speed controllers have a pilot operated design to solve this problem, plus the design provides a backup to the circuit in case the air pressure is lost in the system. A pilot operated speed controller will retain the air in the cylinder until a pilot signal is sent, lifting up the check valve and allowing the flow of the captive air out of the actuator.

BENEFITS OF SMC DESIGNED SPEED CONTROLLERS

  • Newly developed dial display units provide feedback per a specific number
  • Ten turns of control as a standard with the same percentage of change per rotation
  • More body sizes, metric and imperial threads and multiple locking options on adjustment
  • Mostly designed for one-touch tube connections for easy installation

Deublin Rotary Union Training

OTP Industrial Solutions for Fluid Power Applications
Tim Griffith
Terre Haute, Indiana

I recently returned from rotary union school at Deublin North American headquarters in Waukegan Illinois.

The training was clearly worth my time.  We went over basic operating theory, selection and sizing, disassembly and reassembly, and failure analysis.  We also discussed in detail many rotary union applications for the machine tool, printing, paper, corrogating, plastics, and steel industries.

One of the key things I took away is the appreciation that many people do not install rotary unions correctly. (As much as people like the ball-peen hammer, it is not the tool to use!) There is a specific sequence required to insure that the internal workings of the rotary union are not damaged during installation. Connect the hose first to the rotary union. Then install the rotary union to the respective piece of equipment. (Did you see that? Free advice!)

As important as the technical knowledge that I gained were the relationships that I built.  The Deublin people were great and I know they will support OTP when we need it.  Even more impressive, I was but one of sixteen technical OTP salespeople from six different OTP locations at the training.   I even found out that we currently repair Deublin rotary unions in our Fort Wayne shop.

We sure do have a lot of strong technical associates at OTP!

SMC Pneumatic Cylinder Operates in Corrosive Atmosphere

OTP Industrial Solutions for Pneumatic Applications
Darrel Lithgow
Indianapolis, IN

I was working with a machine builder in Indiana that builds OEM machines for the medical equipment industry.  The customer was experiencing failures and unacceptable operating life with the pneumatic cylinders that they used to move parts into an acid bath.  Although the cylinders were constructed of stainless steel, they exhibited premature shaft wear which caused the cylinders to fail in the corrosive atmosphere.

After investigating the application, we determined that the cause of the premature shaft wear was the design of the cylinder bushing. After understanding the root cause, we  replaced the failing cylinders with a specially designed SMC Pneumatic cylinder. This special SMC Pneumatic cylinder utilizes a different (and better!) bushing design than the other manufacturer’s cylinder.

The special SMC Pneumatic cylinder has now been in service for more than six months and is holding up much better than the other manufacturer’s product. The operating life of the SMC cylinder is at least double that of the previous cylinder.

Due to SMC Pneumatic’s ongoing attention to reducing their internal manufacturing costs, the customer’s purchase price of  this specially designed cylinder was actually less than that of the competitor’s standard cylinder!

As an SMC Pneumatic Technical Distributor (and a self described “airhead”), this is just another example of how I apply my technical knowledge to engage SMC engineers to solve customer pneumatic applications.
