Lift Check Valve Manufacturer in India

Speciality Valve is a trusted Lift Check Valve Manufacturer in India, supplying precision-engineered valves designed to allow one-way flow and prevent reverse flow in critical piping systems. Our lift check valves ensure reliability, efficiency, and safety across industries such as oil & gas, petrochemical, power, and water treatment.

Function & Working

Lift check valves operate automatically to prevent backflow. The valve consists of a disc that lifts vertically from the seat when fluid flows in the forward direction. When the flow stops or reverses, gravity or a spring pushes the disc back onto the seat, creating a tight seal. This design ensures quick shut-off and dependable operation in horizontal or vertical pipelines where high flow velocity is present.
