Electric single rotary actuator
Such implementing agencies similar to electric rotary actuator, the main difference is the executing agency of the final output is 1/4 turn in mind the 90 degrees of movement. The new generation of electric single rotary actuator combination of most of the complex functions of the rotary actuator, for example: use of non-access-user-friendly operator interface parameter setting and diagnostics.stainless steel pneumatic cylinders
Single-turn actuators are compact can be installed to the small size of the valve, usually the output torque of up to 800 kilograms of rice, the other should be required less power, they can install the battery to achieve fail-safe operation.standard air cylinder
Fluid-driven multi-rotary or linear output implementing agencies
The implementing agency of this type often used to operate through the valve shut-off valve and gate valve, pneumatic or hydraulic operated. Simple structure, reliable work, easy to implement fail-safe operation mode.
Usually people use electric rotary actuator to drive the gate and globe valves, only when there is no power to consider the use of hydraulic or pneumatic actuator.direct acting solenoid valves
