About Us

Speciality Valve is the best Check Valve Manufacturer in India. We supply to West Bengal, Haryana and Punjab. A check valve, also known as a non-return valve, one-way valve, or clack valve, is a mechanical device used in various fluid systems to allow the flow of fluid in one direction while preventing reverse flow. It is an essential component in pipelines, plumbing systems, and machinery where controlling the direction of fluid flow is important. Unlike other types of valves that regulate flow direction or pressure, check valves are designed to allow fluid to flow in only one direction while preventing reverse flow.
The working principle of a check valve is relatively simple. It consists of a valve body with an inlet and an outlet, and a movable component, such as a disc, flap, or ball, which is positioned inside the valve. This movable component is designed to allow fluid to pass through the valve in one direction while blocking flow in the opposite direction. When fluid flows in the desired direction, it exerts pressure on the movable component, causing it to move away from the valve seat and allowing fluid to pass through the valve unrestricted. However, if the fluid tries to flow in the opposite direction, the pressure from the fluid pushes the movable component against the valve seat, creating a seal that prevents reverse flow.
We manufacture Check valve in various designs, but their main principle of operation remains the same.
