The gear actuator can be installed directly on the gate valve, globe valve and so on. By using Spiral bevel gears and thrust ball bearing, the gear actuator 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 Protection grade can be IP65. The gear actuator can drive multiple valves. When the complex working condition and the installation environment is limited, we choose a universal coupling, in this way one electric actuator, hydraulic motor, hydraulic station or manual gearbox can open and close the valve in the same time. And also make the echelon ratio according to the valve open and close time, to achieve a multipurpose machine.

The user can machining the stem nut diameter according to the Max-stem dia. And pay attention to the coaxiality of the base A, when machiming inner hole. The material of the stem nut is brass H62, bronze H94,alloy tool steel D2,ductile iron GGG45. You can choose according to the demand.
