This is a brand new directional control valve, made in Taiwan, Youli brand high-quality 120Lpm monoblock valve. It is designed for any application where you need to control 2 individual functions or cylinders. It has a 'power beyond' port 'C', which gives the valve the ability 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 the center position. If using this to spin a motor, a motor spool is recommended. If your motor is spinning fast, the centrifugal force if shut off the 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. Port sizes are 1" & 1.1/4" Bspp. See below

This is a High-Quality Valve and has many outstanding features, including.
the built-in adjustable relief valve
high performance
high efficiency
small volume
mass flow
leak resistance.
In addition to compact size, these control valves have fixed and large pull rods to control the direction
Please note
These 80 LPM valves require a separate "Power Beyond" sleeve to operate a valve downstream.
The detent is when you push/pull a lever, it stays forward/back at that position until you move it back to the center.
Installation
As per photos, there is 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 either equal or lesser volume). A & B ports run to your cylinder or other functions.
