Non slam check valve, Nozzle Check Valve, Axial Flow Check Valve, Check Valves offerd by Vatac are not limited to conventional types of Swing & Piston, also in Dual Plate, Non-slam and other specials. Vatac Check Valves are designed and manufactured to the most updated int’l standards. A check valve allows fluid to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and/or cheap. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.
STANDARD FEATURES OF VATAC CAST IRON CHECK VALVES ● LOW FUGITIVE EMISSION SERVICE
Vatac standard Cast Iron check Valves are designed and manufactured to ensure low leakage to international standards, Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the Vatac stem packing seal area and in the bonnet gasket sealing area, In-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the Vatac cast iron check Valve meeting a maximum of leakage prior to shipment.
