Pressure
Reducing Valves are designed to reduce the maximum pressure
in a portion of a hydraulic circuit" the valve is open from
the inlet to the outlet until a pre-selected pressure is reached,
at which point the valve closes to limit pressure in the secondary
circuit. The need for a separate power source for each pressure
level is eliminated.
Valve
seats and poppets are precision ground, assuring virtually zero
leakage and eliminating the need for a case drain line. The drain
port (T) is used only during set up of the internal safety relief
valve. This adjustable relief valve can be set to just above the
reduced pressure setting so it will open only if contamination
or another malfunction prevents the pressure reducing valve from
closing, causing the outlet pressure to rise above the relief
valve setting. The drain port should never be plugged, although
it is seldom permanently plumbed into the circuit.
Features:
- Valves
are adjustable from 1,000 to 5,000 psi outlet pressure
- Internal
check valve allows free flow in reverse direction
- Maximum
flow rate at 5 gpm
- SAE
or manifold mount
- Automatically
reopens to replenish lost pressure
