MAIN OPERATING FEATURES
Max working pressure 350 bar
Max flow 25 l/min.
Installation torque 40-45 Nm
Outside surfaces are zinc coated
Valves are set,after testing, at 100 (-5/+10 bar), 180 (+/-10 bar)
and 350 (+/-20 bar) with 5 l/min. flow
All components are made in high quality steel.
The poppet is hardened and ground.
Pressure Relief Valves are normally closed pressure control
elements designed to keep a constant pressure difference between
inlet port '1' and outlet port '2' when oil flows through the valve.
Direct acting valves are normally used to protect hydraulic
actuators from shock pressures; the direct action allows a very
fast opening and closing.
Hysteresis is very low.
Seat design is leak proof.
Quite operation.
