Piston Valves for High-Pressure and High-Temperature Industrial Applications

Piston valve is a type of valve that uses a piston moving up and down within the valve body to control fluid flow, allowing for opening, closing, and precise flow regulation. It features excellent sealing, robust construction, and the ability to withstand high pressure and high temperature, effectively preventing leakage and ensuring system safety. Piston valves are widely used in steam systems, gas pipelines, high-temperature and high-pressure liquid transport, chemical processes, power systems, and oil and gas pipelines. They are especially suitable for applications requiring high pressure, high temperature, or precise flow control. By regulating the movement of the piston, piston valves reliably control fluid flow while protecting downstream equipment and improving overall system efficiency.

A plunger valve is a control valve widely used in industrial fields. Its working principle involves a plunger that moves up and down to open, close, or regulate fluid flow. Compared with traditional ball valves and butterfly valves, plunger valves have a simple structure, superior sealing performance, and long service life, making them favored in petroleum, chemical, natural gas, water treatment, and pharmaceutical industries. Domestic design standards include JB/T 12526, JB/T 12954, or it can be designed according to ASME B16.34 or GB/T 12224.
