INDUSTRIAL CHECK VALVE

Our firm is enlisted as one of the renowned names for supplying Check Valve. Check valves are used in chemical and power plants for effective regulation of fluid. Entire stock is manufactured by using superior quality raw materials. Our valves are appreciated for long functional life, durable quality and economic nature. We offer Check Valve to our precious clients, with the promise of timely delivery of our consignment.

Swing Check valve
A swing Check valve consists of a valve body, a bonnet, and a disk that is connected  to a hinge. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve seat when upstream flow is stopped, to prevent back flow.
The disc in a swing type Check valve is unguided as it fully opens or closes. There are many disk and seat designs will available, in order to meet the requirements of different applications.
The check valve allows full, unobstructed flow and automatically closes as pressure decreases.
These swing check valves are fully closed when flow reaches zero, in order to prevent backflow.
Turbulence and pressure drop in the valve are very low.
The seat design of a lift Check valve is similar to a Globe valve. The disc is usually in the form of a piston or a ball.
Lift Check valves are particularly suitable for high-pressure service where velocity of flow is high. In lift Check valves, the disc is precisely guided and fits perfectly into the dashpot. Lift
Check valves are suitable for installation in horizontal or vertical pipe-lines with upward flow.
Flow to lift Check valves must always enter below the seat. As the flow enters, the piston or ball is raised within guides from the seat by the pressure of the upward flow. When the flow stops or reverses, the piston or ball is forced onto the seat of the valve by both the backflow
