Industrial hydraulic type S-L1X check valve large size large flow 15000L/s sub-plate/flange

Function and configuration

The check valve type S permits free flow in onedirection and closure in opposite direction withleakage.
It basically comprises of the housing (1), poppet(2) compression spring (3) and the spring seat(4).The stroke of the poppet (2), which is guided on
its outside diameter, is limited by a mechanicalstop----the spring seat(4). The built-in compressionspring (3) supports the closing movement. The
compression spring(3) holds the poppet (2) in theclosed position even when there is no flow throughthe valve.
When fluid flows through the valve in the opendirection, the poppet (2) lifts due to the fluidpressure. In the opposite direction the compression spring (3) and the fluid presses the poppet (2) onto its seat (4) and thus closes the connection. For check valves without spring, the fixed position should ensure that the poppet can locate itself closed under its gravity.
