A Forged Steel Piston/Lift Check Valve is a type of check valve designed to prevent backflow in a piping system. It is constructed from forged steel, which provides high strength, durability, and resistance to high pressure and temperature conditions. The valve features a piston or lift mechanism that allows fluid to flow in one direction and automatically closes to prevent reverse flow when the flow stops or reverses.

Key Features:
-
Material: Made from forged steel, offering excellent mechanical properties and resistance to corrosion, high pressure, and temperature.
-
Design: Utilizes a piston or lift disc that moves vertically within the valve body to allow or block flow.
-
Function: Ensures unidirectional flow, preventing backflow and protecting equipment and pipelines.
-
Applications: Commonly used in industries such as oil and gas, petrochemical, power generation, and water treatment, where high-pressure and high-temperature conditions are prevalent.
-
Advantages:
-
High reliability and durability.
-
Suitable for harsh environments.
-
Low maintenance requirements.
-
Provides a tight seal to prevent leakage.
-
Operation:
-
Forward Flow: When fluid flows in the desired direction, the pressure lifts the piston or disc, allowing the fluid to pass through.
-
Reverse Flow: When the flow stops or reverses, the piston or disc is forced back into its seat by gravity or spring action, effectively sealing the valve and preventing backflow.
