API 6D defines a double-block-and-bleed valve (DBB) as a “single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a...
Valves used in seawater systems are always subject to metal corrosion due to the exposure to seawater, so their life period gets reduced shorter. On top of that, there are maintenance hurdles from sea...
All diaphragm valves are bidirectional. They can be used as on-off and throttling valves. Diaphragm valves offer advantages in certain low-pressure applications not possible with other types of valves....
What is Bronze? Bronze is one of the original metal alloys. Using copper and tin, metal workers developed a material that was both strong and malleable, meaning it would not crack as easily as something...
Plastic valves are made from plastic materials and are used in applications that require corrosion resistance and/or chemical handling. There are many types of plastic material, including...
Basket strainers and Y-Strainers each have design parameters that will affect their success in specific applications. Taking a little time to identify application specifics will ensure that you select...
Valves are important parts of a hydraulic system. Depending on the application, the type and number of valves used will vary. The primary duties of valves are to direct the flow of fluids, regulate...
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of...
A knife gate valve is a component that utilizes a blade to cut through clogging of heavy liquids. These valves were designed to work in some of the most corrosive, erosive and abrasive environments...
