CHECK VALVE

We are leading manufacturer, supplier and exporter of high quality Non-Return valves. This valve allows a medium to flow in one direction. This valve ensures that the medium or fluid flows through a pipe in correct direction which can be known itself from its name as the fluid goes through one direction so its name is Non-return valve. These valves are easy to install and are designed in a way to handle maximum product pressure. Additionally these Non-return valves are made with high grade raw materials and manufactured in compliance with international standards. Non-Return valves are generally used with mixing loops in cooling or heating systems to make sure that the operation is accurate and to prevent back flow. There are various kinds of Non-Return valves such as:   1) SWING CHECK VALVE Swing check valves are generally used in the systems employing gate valves as the low pressure drop around the valve. The name itself says Swing check valve as the disc in the valve swing away to seat to allow flow in correct direction. Our Swing check valve are highly demanded due to its unique features such as renewable, easy to install and meet all the requirement of its different applications.

Operated Type Self Operated   2) Dual plate CHECK VALVE The Dual Plate Check Valve is widely usable Non-Return Valve which is comparatively light in weight and stronger and also is small in size if compared with conventional Swing Check Valve. The Dual Plate Check Valve is uniquely designed by us and has also solved the problems which were faced with Swing Check Valve and Lift Check Valve. This specially designed Dual plate check valve utilizes two spring loaded plates attached on a central hinge pin. When the flow is reduced then plates are closed by torsion spring action and do not require reverse flow. There are two major advantages of No water hammer and Non-slam all together. All these feature of Dual Plate Check Valve make it the most unique and efficient design. Technical Specifications Sizes DN15 to DN 1200 ( ½”  to 48” ) Pressure Rating Class 150, 300, 600, 900, 1500.
