Screw down hydraulic gate valve

 In accordance with SOLAS. The valve operation mechanism of Fore Peak Ballast Tank inner side installed SCREW DOWN VALVE(Globe or Gate Valve) is changed from previous piston type and /or rack & pinion linear type to screw down type. The multi-turn hydraulic actuator is our company’s independent research and development of such functional products.

The screw down (multi-turn) hydraulic actuator can be installed directly on the gate valve, globe valve and so on ; By using spiral bevel gears and thrust ball bearing. So it can run smoothly and have high output torque, low noise and high efficiency. It can avoid from waterproof & oil leakage as sealing glands are used at all the through part. And the protection grade can be IP65(special manufacturing can be IP68).

This products can become screw down electro-hydraulic actuators which the screw down electro-hydraulic actuators have the advantages of small volume, fast running speed and more stable operation than the electric actuators.
