Key Features

ARITA Forged Stainless Steel Lift (Piston / Y-Pattern) Check Valve
ARITA forged stainless steel lift check valve is designed to allow flow in one direction and automatically prevent backflow when flow stops. The piston-type disc provides stable and reliable closing performance for high-pressure service.

Class 800 Pressure Rating
Designed for Class 800 applications, suitable for severe pressure conditions commonly found in chemical, oil & gas, power generation, and high-pressure utility systems.

Forged Stainless Steel Construction
Available material options:

• SS304 (ASTM A182 F304)

• SS316 (ASTM A182 F316)

Forged stainless steel construction offers excellent pressure integrity, corrosion resistance, and long service life compared to cast valves.

Integral Hardfaced Seat
Integral hardfaced seat improves wear resistance and sealing performance under high pressure and repeated cycling.

Threaded NPT or Socket Weld End

• NPT threaded end: ASME B1.20.1

• Socket weld end: ASME B16.11

Ideal for compact, high-pressure piping layouts.

High-Integrity Bonnet Design
Bolted bonnet or welded cover design ensures secure pressure containment for critical service applications.
