Non Return Valve

Siemag Non Return Valves or popularly known as Check Valves are manufactured with precision engineering and the finest of materials.

These NRV's operate one way and prevent reversal of flow of media in the opposite direction. Soft seating arrangement results in zero leakage at back pressure.

Available in a choice of material which includes metallic and nonmetallic grades with screwed ends. These valves are opened by the flow of the fluid in one direction and are closed by spring action or by backpressure in the reverse direction.

Designed to open at very low (cracking) pressures these Check Valves are also offered for high.

Features

• Allows free flow of air in one direction only.
• Simple, reliable design
• Light weight.
• Low cracking pressure.
• Performs well in any orientation
• Bubble tight - seat

Application

These NRV find usage in a number of applications such as oil, gas, water, refining, steam, and chemical industries. The non return valves can be availed in a choice of three kinds which include Extruded, forged and cast. These valves can pressures application of up to 10000 PSI with minimum pressure drop. The nonmetallic check valves are used in corrosive media and are resistant to alkalis, chemicals and hazardous gases. The special design also ensures high discharge with low friction.
