- Piston Check Valve
Falcon Flow Control Piston Check Valve
A robust check valve featuring a guided piston-type closure element, designed for reliable backflow prevention in vertical or horizontal installations with high pressure and temperature conditions.
Full Description
The Falcon Flow Control Piston Check Valve uses a precision-guided piston as the closing member, moving axially inside a cylindrical body to allow forward flow and prevent reverse flow. This valve design ensures tight sealing with minimal wear, suitable for demanding industrial applications where space and flow direction versatility are critical.
The guided piston mechanism provides stable and reliable operation under varying flow velocities and pressures. Piston Check Valves are especially favored in power plants, steam systems, and petrochemical industries for their durability and ability to handle high temperature and pressure fluids.
Constructed with high-quality materials, Falcon’s Piston Check Valves offer excellent corrosion resistance, longevity, and low maintenance. The valve design also minimizes water hammer and flow turbulence.
