LVCS-1 type spring return check valve

A forged body check valve manufactured according to API 602 Standard with up to 50 mm nominal size, for wide pressure-, and temperature ranges. The piston type check valve is made with helical spring returning closing element. The valve can be installed only for one way streams. In case of back stream the valve closes due to spring force and the pressure of medium. The valve seat and the disc is welded with Stellite 6 for the purpose of excellent wearing resistance. The sealing of the bonnet is highly flexible spiral wound gasket. At higher pressures the sealing is made of stainless steel gasket ring. The check valves can be manufactured also with threaded valve seats on demand.
