Brand: ARITA
Key Features
ARITA Forged Steel Lift (Piston / Y-Pattern) Check Valve
ARITA forged steel lift check valve is designed to allow flow in one direction and automatically prevent backflow when flow stops. The piston-type (lift) disc provides stable closing performance for high-pressure services.
Class 800 Pressure Rating
Designed for Class 800 service, suitable for severe pressure conditions commonly found in oil & gas, petrochemical, power generation, and high-pressure utility pipelines.
Forged Steel Construction – ASTM A105N
-
Body & cover: ASTM A105N forged steel (with Stellite hardfacing on seat)
-
Disc: ASTM A276 Type 420
-
Gasket: 304SS spiral wound with graphite
-
Bolting: ASTM A193 Gr.B7
Forged steel construction provides superior strength, pressure integrity, and reliability compared to cast valves.
Integral Hardfaced Seat
Integral hardfaced (HF) seat improves wear resistance and extends valve service life under high pressure and cyclic operation.
Threaded NPT or Socket Weld End
