About A217 WC6 Cast Alloy Steel Piston Valve

A217 WC6 Cast Alloy Steel Piston Valve is widely acclaimed among our customers owing to its superior design and quality. The piston valve has got ruggedness and high build quality. It is made out of the first-rate alloyed metal that is resistant to chemical attacks, heavy pressure, abrasion, and other degrading factors. For this reason, the tool does not degrade in quality or performance for years. It is typically used to control the pressure and flow rate of fluids and maintains unidirectional flow. A217 WC6 Cast Alloy Steel Piston Valve can be purchased from us at a cost-effective price.

Full port forged steel isolation valves with a maximum operating pressure of 1973 psig/136 Barg and a maximum operating temperature of 800oF/427oC. The burnished piston and metal reinforced graphite rings provide leak-proof shut off and allow Piston Valves to be operated at higher temperatures, while also extending operating life.

Piston Valves are available in Socket Weld, BSPT, and NPT end connections. Flanged ends can be supplied upon request. Piston Valves are ideal for saturated and superheated steam, and hot water applications.
