Non Return Valve Manufacturer in India

Product Description

FlowBiz Non-return valves use the mechanism to allow the medium only in the downstream direction.

It has two openings:

One inlet and the other one outlet. A closing member separates the inlet and outlet, waiting in between. When the fluid enters the non-return valve via the valve inlet, the fluid pressure keeps the closing member open. On the other hand, when the fluid attempts to flow backward from the outlet side to inlet side, Closing member closes the entrance, preventing the flow. Our Non-return valves work automatically without the need for control of any external element.
