    摘要： A directional control valve comprising: a body, an actuator configured to switch the directional control valve between two or more states, a manual activation button configured to initiate actuation of the actuator when pressed, a safety member configured to slide along a guide of the body between a first position and a second position, a coupling member configured to couple the directional control valve to other directional control valves, and a guard removably disposed between the safety member and the coupling member. The safety member prevents the manual actuation button from being actuated when it is in the first position and the manual actuation button can be manually actuated when the safety member is in the second position. In addition, the guard is configured to prevent the safety member from sliding to the second position when the guard is disposed between the safety member and the coupling member.

    摘要： A manual override assembly for a hydraulic power source is disclosed with twin spool valves, connecting rods, retaining plug assemblies, and a lever arm, where the spool has a bore with an off-set opening for inserting one end of the connecting rod, where the connecting rod connects the spool to the lever arm, and where the retaining plug assembly is used to mount the manual override assembly to the body of the hydraulic power source.

    摘要： Auxiliary manual operation on a bistable multiway valve is achieved with a valve member able to be reciprocated with the performance of a switching movement and furthermore operating device extending athwart the direction of the switching movement. There is a provision such that the operating device includes at least two mutually parallel plungers, which on operation act on second different flanks of the valve member, operation of one plunger locking the respectively other plunger.

    摘要： A gate valve hydraulic actuator having a stem extension accessible from outside the actuator body to provide override operation of the gate valve, for example in the event of hydraulic failure. The stem extension is lockable to a spring compression hub in a valve open position and a valve closed position by locking dogs selectively engageable in recesses. The locking dogs are operated by a cam spindle coaxially received in the stem extension.
