Product description
Technical parameters

Forged Steel Check Valve
YUMING's Horizontal Piston Type Forged Steel Check Valve is available with screwed and flanged ends, featuring a heavy rugged body with a bolted cover design. Designed in compliance with API 602, BS 5352, and ASME B 16.34 standards.
It is available in end connections of socket weld, butt weld, and threaded (screwed) BSP or NPT, with pressure ratings of Class 800# and 2500#.
The YUMING piston-type horizontal lift-type forged steel check valve incorporates a self-cushioning effect, with a body-guided piston ensuring accurate return to the seat ring to achieve leak tightness.
YUMING's manufacturing range covers both regular port and standard port types of Forged Steel Check Valves.
Forged Steel Piston Lift Check Valve screws are available in a wide range of body materials, such as ASTM A 105 - Forged Carbon Steel, ASTM A 182 F 304/304L/316/316L, and ASTM A 182 F 11/22 - Alloy Steel, to suit various industrial applications.
For high-pressure and high-temperature applications, Stellited F6 face seat and disc are available.
