The company shares glorious credentials with the leading Suppliers of Air Wafer Type Non Return Valve and offers the best deal. As we remain much concerned about the safety of the products, we store the entire lot in our capacious warehousing unit under secured environment and expert's supervision. Details : Spring closing arrangement for the prevention of reverse flow in pipelines. These valves are general-purpose valves that are stronger, lighter and smaller than conventional swing check valves and therefore, less expensive to install and maintain. Suitable for higher pressure/temperature (up to 400*C) Compact Design for simple installation between wide ranges of flange types. It can be mounted in any plane/direction. Extremely low opening pressures. Available sizes 15mm to 100mm, suitable for PN6-PN40 and ANSI 150/300. Weight and Dimension are same for class 150 & class 300 valves. Valves are self-centering type. Zero leakage for soft seated valves. The maximum permissible leakage rate shall be 3 cubic centimeters per inch of nominal pipe size for metal-seated valves. Testing - As per API 598 Design - As per manufacturers standard. Material of Construction : Body : AISI 316, WCB. Disc : AISI 316 Spring : Standard AISI 316 Spring Nimonic - for high temperature up to 400c Disc Seat - Standard, EPDM/Nitrile, Soft seated-for water-silicon/viton soft disc seating face - for oil & gases. General Construction : Metal to Metal seated Construction Soft seated (EPDM/Nitrile/ Silicon/viton) construction. Pressure Rating : PN 40 Flange Standard : BS 10 Table D, E *& H DIN: PN6, 10 16, 25, 40 ANSI 150 and 300 Operation : Non Slam Check Valves are opened by the pressure of the fluid and closed by the spring as soon as flow ceases and before reverse flow occurs. Installation : Non Slam check valves simply fit between two pipe flanges Standard gaskets are used on either side of the valve together with longer bolts or studs.
