Middleeast valve is the largest and most demanding Lift check valve supplier in Dammam. We supply to Dhahran, AI Khobar, Jubail, Muharraq, and AI khor.

A lift check valve is a crucial component in various fluid systems, serving a vital role in preventing backflow and ensuring the unidirectional flow of fluids. This type of valve operates automatically, allowing the fluid to flow in one direction while preventing reverse flow.

Design and Construction:

Lift check valves, also known as non-return valves or one-way valves, come in various designs, but they share a common principle: they allow flow in one direction and prevent flow in the opposite direction. The valve typically consists of a body, a disc or poppet, a spring (in some designs), and a seat. The disc is lifted off the seat when there is forward flow, allowing fluid to pass through. When the flow stops or reverses, the disc settles back onto the seat, preventing backflow.

Working Principle:

The working principle of a lift check valve is straightforward. When there is forward flow in the system, the fluid exerts pressure on the disc, lifting it off the seat and allowing the fluid to pass through. The lifting of the disc is typically aided by the flow momentum. When the flow stops or reverses, gravity and the design of the valve force the disc back onto the seat, sealing the valve and preventing backflow.

Some lift check valves include a spring mechanism to assist in closing the valve promptly, ensuring a tight seal and preventing any reverse flow. The spring is calibrated based on the application requirements.

Lift Check Valve, available from suppliers in Dammam, excel in minimizing water hammer and ensuring a secure seal. However, their enhanced performance comes with a higher cost and greater maintenance demands due to their intricate construction.

 Advantages of lift check valve:
