Product Description


Proportional multi-way directional spool valve type HLPSL and HLPSV according to load-sensitive principle are mainly applied to Engineering Machinery electric hydraulic control field to control the movement direction & speed of hydraulic oil cylinder or hydraulic motor. With various functions such as electric proportional control, electric switching value control, hydraulic control, pneumatic control, manual control, etc., such valves can realize stepless speed regulation and will not be influenced by load change. The characteristic of load sensing enables the multi-way actuators to run simultaneously and independently from each other at different speed and pressure ratings until the maximum flow of bumping source is reached.

For 3 series constant displacement pump system, The safety pressure is set as 350 bar, each directional spool valve has the differential reducing valve. While L valve Core is on Neutral position, P、A、B、R port is closed ; While H valve Core is on Neutral position, P port is closed and A、B port is open to R port. A、B port of 1st directional spool valve flow is 40L/min, and A、B port press is not more than 300 bar, for the 2nd directional spool valve A port flow is 40L/min, B port flow is 25L/min, for the 3rd&4th&5th directional spool valve, A&B port flow is 16L/min, for the 5th directional spool valve pressure should not more than 250bar. The end plate is Standard, and the T port is connected externally to oil tank.
