Stainless Steel swing check valve is used mostly in the water flow systems. The check valves or tilt disc valves are useful for backflow prevention. Suraj Metal Corporationis a leading supplier and manufacturer of the Stainless Steel inline check valve and other types of the check valves. The valves have a check disk inside them that allows the flow of water in a unidirectional flow.
The disc allows for the flow with minimal force with ½ lb cracking pressure. But the backflow is completely blocked. The cf8m check valve and other types are made in different material grades. The most used is the stainless steel 316 with casting body. The working pressure of the valves is up to 200psi. These can be used in full range of liquids and gas. The Stainless Steel wafer check valve can have a temperature range from -40F to 400F. The valves are useful in high pressure flow systems and low pressure flow systems as it prevents backflow and facilitates unidirectional flow with minimal force. Please contact us to know more about the different types of the Stainless Steel spring check valve and the other types. You can also get a complete price list and full catalog from us.
