Lift Check Valve - Stainless Steel Body, 2-inch Size , Automatic Operation With Spring-assisted Closure

Design:
Body Design: Generally, lift check valves have a straightforward design with a body that houses a movable disc or piston.
Disc/Piston: The disc or piston is lifted or moved by the flow of fluid to allow passage through the valve. When flow stops or reverses, the disc/piston seats against the valve body to prevent backflow.
Spring-Assisted (Optional): Some lift check valves may include springs to assist in closing the valve promptly and prevent slam upon reversal of flow.

Operation:
Automatic Operation: Lift check valves operate automatically based on the flow of fluid. When fluid flows in the intended direction, the disc/piston lifts, allowing flow through the valve.
Prevents Backflow: Upon cessation of flow or if flow reverses, the disc/piston seats against the valve seat under gravity or spring force, preventing backflow.

Materials:
Body Materials: Commonly made from materials such as carbon steel, stainless steel, ductile iron, bronze, or other alloys depending on the application and fluid characteristics.
Disc/Piston Materials: Typically stainless steel, bronze, or other corrosion-resistant alloys to ensure durability and reliability.
