This is a brand new, made in Taiwan, Youli brand high quality 80Lpm monoblock valve. it is designed for any application where you need to control 3 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.
