6 Spool 80 Lt/Min BSP Ports Hydraulic Flow Control Valve With Spring Return Closed Center
Hydraulic Flow Control Valve 6-Spool 80 Lt/Min BSP ports with spring return closed center
This is a brand new, made in China, HANJIU brand high quality 80Lpm monoblock valve. Matching Badestnost/Walvoil/Youli/Galtech......it is designed for any application where you need to control 1 individual function or cylinder. It has a 'power beyond' port 'C', which gives the valve the abilty to supply another valve downstream pressure. You must select 'power beyond sleeve ' for this function to work. Please note, you MUST still use a tank return hose from BOTH valves. Standard this comes with a 'cylinder' spool. This will 'lock' your load/cylinder in place when in centre position. If using this to spin a motor, a motor spool is recommended. If your motor is spinning fast, the centrifugal force if shut of dead by a cylinder spool, may cause damage to various components of your system. A motor spool will allow the motor to spin to a slow stop. It will not lock in place. Lever action is Spring Return to Center.
These valves are regularly used in hydraulic circuits to divert the flow of high pressure oil and are typically used to control the speed and movement of hydraulic cylinders or motors.

These 80 LPM valves require a separate "Power Beyond" sleeve to operate a valve downstream.
Detent is when a you push/pull a lever, it stays forward/back at that position until you move it back to the centre.
Installation ; As per photos, there are a choice of two pressure ports "P" (only use one), two "T" Tank return ports and also there is a "C" port. This "C" port is for the: Power Beyond function. This allows another valve to run pressure from this C port downstream if necessary. (must be a lower volume though). A & B ports run to your cylinder or other functions.
