Relief valve, direct acting
poppet type
Description
Pressure relief valve designed for application where pressure ad-
justment and low leakage is request. The valve can be used also as
a safety device to limit the pressure of circuit.
Operation mode
The valve consist in a body, poppet and spring. Pressure is manual-
ly set by the adjustment screw. The spring pushes the poppet into
the closed position. When the pressure exceeds the spring force,
valve opens allowing flow from port 1 to port 2.
