Poppet design
q
One-way throttling check valve
q
Three cracking pressures
Check valves are used to allow flow in one direction and
prevent flow in the other. The poppet design guarantees
leak free closure and so it is allowed throttling only
through orifice plate (5). The seat (3) is created directly in
the housing (1) and the poppet (2) is pushed onto the
seat by the compression spring (4). Design without
spring pushes the poppet (2) on to the seat by presssure
of the fluid. The cracking pressure depends on the spring
selected and the pressurised poppet surface area. Three
cracking pressures are available. The valve without
cracking pressure is also available (without spring).
The basic surface treatment of the valve housing is zinc
coated.
