There are countless types of valves for use across a variety of industries and applications. When it comes to flow control valves, valve types range from simple to sophisticated; some valves are complex enough to adjust automatically to pressure and temperature variations. No matter their constructio...
The more common types of valves, in alphabetical order, include ball valves, butterfly valves, gate valves, globe valves, needle valves, pinch valves, plug valves, poppet valves, and saddle valves. The simplest piping network is a single pipe system for delivering a fluid from one spot to ...
Butterfly valve is one of the most commonly used valve types in industrial valves, especially suitable for low pressure and large diameter applications. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly ...
Common types of piggable valves include three-way diverter valves, non-sanitary ball valves, t-port valves and retractable auto pig stops. Non-piggable valves refer to valves that do not permit the free travel of the pig i.e. butterfly valves. Although they aren’t piggable, they still pla...
Control valves are mechanical devices with moving parts, and as such, they are subject to friction, primarily between the valve stem and the stem packing. Some degree of friction is inevitable in valve packing and in some types of trim where components must move past each other throughout the...
