PROPORTIONAL, PRIORITY TYPE, PRESSURE COMP,
FLOW CONTROL VALVE.
DESCRIPTION
This valve is a cartridge style, electro-hydraulic, proportional,
priority (BY-PASS) type, pressure compensated, hydraulic flow control.
Regulated flow 20.0 GPM [76,0 L/M] max. is proportional to the current
input regardless of load or system pressure. After the priority flow
is satisfied the excess flow is diverted to a secondary circuit or to
tank. Maximum inlet flow is 35.0 GPM [130,0 L/M].
OPERATIONS
This unit is a direct acting (NO PILOT FLOW), electro hydraulic, pro-
portional, pressure compensated, flow control valve. When the coil is
energized the armature moves the metering orifice open against a pre-
cision bias spring varying the flow. A pressure compensator spool
(HYDROSTAT) modulates the flow at 100 PSI/6,9 Bar delta "P" providing
the valve with a constant regulated flow regardless of load or system
pressure. When current is increased to the coil the flow will increase,
as the current is decreased the flow will decrease proportionally.
IN THE EVENT OF POWER FAILURE THE VALVE WILL CLOSE.
FEATURES AND BENEFITS
Continuous-duty, very low heat rise & waterproof solenoid coil.
Interchangeable solenoid coils & terminations options available.
Hardened precision fitted spool & sleeve provides reliable, long life.
Very efficient wet - armature solenoid core tube construction.
All external carbon steel parts are plated for longer life against the elements.
All cartridge valves are 100% functionally tested.
