Functional Description
Pressure relief valves VPP2-06 were designed for
applications requiring a safety valve or a pressure
regulating valve working over a wide range of pressures
and flow rates.
The valve basically consists of the valve body (1), poppet
with damping spool (2) and compression spring (3).
Pressure is manually set by an adjustment screw (4). The
spring pushes the poppet into the seat (5) holding the
valve in its normally closed position. When the force,
caused by the pressure acting on the exposed surface
area of the poppet, exceeds the spring force, the valve
opens and the flow passes from port P to port T.
To optimize the valve performance, five pressure ranges
are available. Choosing the closest range is
recommended. The design enables the valve to be used
as a screw-in cartridge for manifold mounting, built into
a threaded housing or in a subplate mounted housing.
Both the threaded and the subplate mounted housings
can be delivered either with metric or pipe threads.
The basic surface treatment of the valve body and the
adjustment screw are zinc coated.
