Non Return Valve

Name itself suggest the functional area of valve. It is used to prevent the flow of the medium to reverse direction. So in turn, medium will flow in only single appropriate direction and not in back direction.

We have designed large series of non return valves for different operations. We monitor each and every level of production to offer highly precise non return valve. We provide highly efficient non return valves that can withstand with high pressure drop of the system.

It is commonly used in domestic water system. It is also used in several heating and cooling systems.

Non Return Check Valve

Non return check valves are used to avoid back flow of gases and fluids. It allows medium to flow in single direction only. It provides tight shut off at reverse flow direction.

It is used reliably for the safe operations that includes corrosive chemicals and fluids.

Non return check valves offer automatic function. It does not contain stem or handle for the operation. The operations that possess dealing with hostile or aggressive fluids seek precise flow control. Non return check valves are used for corrosive applications.

Non Return Swing Valve

To offer a reliable quality non return swing valves for the safe and sound operation, we have employed proper combination of best fabrication technology and high quality construction material.

Furthermore we stringently follow international manufacturing standards for the production of the non return swing valve. We have developed the series of non return swing valve that can be operating at high temperature and high pressure.

Non return swing valves consist of swinging disc that swings on a hinge. It effectively blocks the reverse flow of medium. It is specially designed to offer smooth sealing. It works automatically with reverse pressure of medium. According to application, our swing valves are provided with varied packing and gasket options. It is available with PTFE/graphite and asbestos. It contains flanged and butt welds end connections. It is designed as per design code BS-1868 and testing as per BS-5146
