Product name：Standard Piston Check Valve
Product introduction：Check valves to ANSI/ASME standards with threaded socket (NPT), welding ends (BW) or weld sleeves (SW), Trim 8 (Stellite/13% chrome steel), with cover flange, spring-loaded cone, available in carbon and alloy steel.
Application：
1. Boiler feed water
2. Conventional power plants
3. Petrochemical industry
4. Pipelines and oil storage tanks
5. Refinery equipment
6. Process technology
Advantages：
1. The armored sealing surfaces (base and cone) are made of wear-resistant and corrosion-resistant materials, which ensure a long service life and high functional reliability.
2. Reliable sealing. The labyrinth cover seal on both sides prevents the sealing gasket from sagging.
3. Variable use. The closing spring allows it to be used in vertical and horizontal pipes.
4. Reliable sealing between cone and base is achieved by guiding the cone along the inner wall of the housing.
