In accordance with SOLAS. The valve operation mechanism of Fore Peak Ballast Tank inner side installed SCREW DOWN VALVE(Globe or

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.
