Relief valve, direct acting, differential
area, poppet type
Description
Pressure relief valve direct acting differential area, designed for
application where good performance of pressure increase vs flow
and pressure adjustment is requested. The valve can be used also
as a safety device to limit the pressure of the circuit.
Operation mode
The valve consist in a body, poppet and spring. Pressure is manu-
ally set by the adjustment screw. The spring pushes the pilot stage
into the closed position. When the pressure exceeds the spring
force, valve opens allowing flow from port 2 to 1.
