High-Performance Butterfly Valves High-performance butterfly valves have a different structure than that of general use butterfly valves. Referred to as double offset butterfly valves, high-performance butterfly valves have a disc that is offset from its seat center, which is referred to as eccentric. The unique characteristics...
Triple Offset Butterfly Valve A Triple Offset Butterfly Valve features three distinct offsets. Two of the offsets apply to the placement of the shaft in relation to the centerline of bore and disc/seat sealing surfaces. The third offset is the design in the seat cone angle...
Introduction Butterfly valves are a type of quarter-turn valve that is commonly used in a wide range of industrial applications. They are named after the butterfly-like shape of their disc, which rotates around a central axis to control the flow of fluid through the valve. Butterfly...
Introduction Butterfly control valves are quarter-turn valves that use a metal disc to control fluid flow through a pipeline. The disc is positioned perpendicular to the flow, and when the valve is rotated, the disc opens or closes to regulate the fluid flow. Butterfly control valves...
A wafer style butterfly valve is a quarter-turn valve designed to mount between pipe flanges and features a disc mounted on the stem of the valve inside a rubber seat. When the disc and stem are turned 90o, the flow of fluids in a pipe...
The invention of the butterfly valve has allowed for the improvement of processes and applications in various industries. This introductory guide is intended to familiarize you with what a butterfly valve is, how it works, and its design variations. What is a Butterfly Valve? A butterfly valve...
For the safety and efficiency of a variety of processes, we rely on the performance of butterfly valves. How sound a butterfly valve is depends on the integrity of the seal. The valve must be able to withstand the particular working conditions of any given process....
For the last several decades, butterfly valve technology has become increasingly common. Butterfly valves are now used in the processes of virtually every chemical plant. What started off as an ideal quarter-turn function for water applications became a versatile valve made from various materials that...
We rely on valves to stop and seal the flow of media in its various forms: solids, liquids, and gases. Leakage of solids or liquids is relatively easy to spot, but some gas leakage isn’t something that can be detected by the naked eye. With the...
Media flow hydraulic processes and procedures are heavily dependent upon quality valves. Failure in a piping system from faulty valves can incur considerable and costly damage. In some cases, these failures may risk catastrophic property damage or injury and death to workers. Because of the critical...
Solenoids are useful in a wide array of mechanical functions. How does a solenoid work? An electromagnetic coil of wire converts electrical energy to mechanical energy. Positive and negative poles make a linear motion within the electromagnetic field to move the piston either backward or...
For many processes that involve fluid material moving through pipe systems, butterfly valves are needed to stop or regulate flow. With this mechanism, a circular disc is designed to move perpendicular to the passage from fully closed to fully open or anywhere in between. It’s...
What is an actuator? Actuators are a common part of industrial mechanics and everyday life. To put it simply, an actuator is a device that makes a component move or operate tasks. There are two types of actuators: linear and rotary. For mechanics that require a...
Butterfly valves and control valves are two types of valves both commonly used in various processing applications. They both deal with the control of flow in a process, but the terms aren't synonymous. If you're wondering if butterfly valves are excellent replacements for the control...
If you work with petrochemicals at your plant, safety is constantly at the top of your list of everyday concerns. But how do you know just how safe your emergency shutdown valves are? In this post, you’ll learn how you can tell if your emergency...
A butterfly valve restrains the flow of any sort of semi-liquid or liquid you need to process, such as waste, oil, water, or gas. What makes it different from a regular valve is it has a disk that covers the passage to stop the flow...
Zero Offset Butterfly Valve - Rubber Seated The disc rotates around the center axis allowing for a potential 360º rotation. Sealing is achieved by the Disc deforming the soft seal resulting in full friction through the full operating cycle. Double Offset Butterfly Valve - High Performance To allow...
It’s important to pick the ideal device for your chemical or power plant, and the type required depends on its application. Triple offset butterfly valves are often considered the highest standard for virtually any application because they are durable, long-lasting and require minimum maintenance. However,...
Triple offset valves are less susceptible to wear and tear corrosion, and degradation, which makes them the most leak-proof and disaster-proof option for certain applications. Triple offset technology is made without materials that are vulnerable to corrosion. They’re the most durable option regardless of the...
There are huge safety risks that come with using the wrong type of butterfly valve for the temperature and pressure level of your application. Poorly installed butterfly valves can also cause problems. However, even when using a properly installed butterfly valve within its design limits...
General Service Vs. High-Performance Butterfly Valves: What's the Difference? There’s a lot that goes into choosing the right butterfly valve for your application. Different butterfly valves are built to withstand different temperatures and pressure levels, so it’s important you know the ins and outs of your...
Butterfly valves are used for large-scale processing applications that require quick, leak-proof opening and closing. A triple offset butterfly valve is a type of butterfly valve specially engineered to fix the shortcomings of other butterfly valve types. By design, it is the highest level of...
High-performance butterfly valves are an essential component for any company that needs to control the flow of gases or liquids. Although butterfly valves have been used since the early 1930s, their use as an effective, low maintenance mechanism to regulate fluid flow has only recently...
In short, a butterfly valve is a quarter turn rotational motion valve. Just like any other valve, they are used to either start, stop, and regulate flow. This type of valve has been around since the early 1930s and has a wide range of applications...
What Does “Value Valve” Mean? Let's face it, looking for butterfly valves can be confusing. And most companies give their butterfly valves a name that don't mean anything! That's why we call ours Value Valve “a Value in Valving” so you'll know the valve you're getting...
