CHECK VALVE TYPE WZZC 10
SANDWICH PLATE

04.2000r.
Check valves of sandwich plate design are intended for
mating with control valves. They allow free flow of fluid in
one direction and self−acting closure in the opposite direc−
tion. Valves can be mounted in any position as an interme−
diate element between a subplate and a control valve.
DESCRIPTION OF OPERATION
The sleeve 3 with the seat for the spring 4 is fitted in the
housing 1. The spring pushes the poppet 2 to the edge of
port P in the housing 1. When pressure difference in port P
exceeds the cracking pressure determined by the spring,
the poppet will move allowing free flow in line P.
Ports A, B, T serve as flow passages.
