Psv Psl Hydraulic Proportional Directional Control Valve 

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.  Control Valve, Flow Control Valve, Loadsensitive Proportional Spool
