An electromechanical drive linkage pilot valve

Species electromechanical drive linkage pilot valve, characterized in that there are additional growth tank assembly and bidirectional hand throttle. The present invention may be driven in rotation by the motor box hand growth mode, so as to drive hoist hydraulic system and ultimately the valve and the valve opening and closing speed can be adjusted by a bidirectional controlled throttle valve. The present invention achieves a driving motor maintenance and emergency conditions such as power failure by hand gearbox, to control the opening and closing of the valve; simultaneous two-way hydraulic system for opening and closing the throttle technology two states are speed regulation , can effectively eliminate water hammer. Its structure is simple, lightweight, modular installation, improving safety and reliability.
