The basic construction of a plug valve is practically identical to that of a ball valve with the exception of the shape of the obstructer used. In this case, the ball is replaced by a slightly tapered cylinder. This cylinder has a bore through it just like a ball valve, and it operates the same […]

Quarter-turn 2-way ball valves are by far the most common type of process control valve. They are 2-way (inlet and outlet), 2-position (open and closed) valves that are used for shut-off or isolation of a system, or a loop or component within a system. The basic construction of a ball valve includes a ball as

There are 2 distinct types of linear valves: rising stem (multi-turn) and axial. While both valve types rely on the linear motion of the flow obstructer, they are very different in construction and operation. Multi-turn rising stem valves move the obstructer by the rotation of a threaded rod (stem) which is attached to the obstructer

These types of valves rely on the rotary motion of the flow obstructer In most cases this rotation is limited to 90 degrees (one quarter-turn), however, there are valves that operate using a larger degree of rotation and have more than 2 positions that are used in regular operation. Valves that are truly quarter-turn are

Posted by Tori Valigura on Jan 22nd 2020 What is a Pressure Safety Valve? (PSV) A Pressure Safety Valve, also referred to as a pop-off valve, is a type of Pressure Relieving Device (PRD) that is used to release gases or liquids, and thus relieve pressure, in the case that the pressure in a vessel

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 forward-backward movement, a linear actuator moves in this direction

When it comes to the world of commercial butterfly valves, not all devices are created equal. There are many differences between the manufacturing processes and devices themselves that change the specifications and capabilities significantly. To properly prepare for making a selection, a buyer must learn the technology and the differences in each variety to choose

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 valves you have, then keep reading. What is a Control Valve? A

Choosing the Right Butterfly Valve: Double Offset vs. Triple Offset When selecting the right valve for your industrial process, understanding the difference between double offset butterfly valves and triple offset valves is critical. Each design offers unique performance characteristics suited for specific pressure ratings, media types, and temperature conditions. Whether you are engineering a chemical
