The driver for valve includes a multi-turn type and a part-turn type. The multi-turn type is an actuator that is used for gate, globe, and other valves and that transmits torque to a valve by being turned at least one turn. The part-turn type is an actuator that is used for butterfly, ball, and other valves and that transmits torque to a valve by being turned less than one turn.

This Is a Fine Testimony to Their Safety.

Seibu valve actuators are used to control such fluid as water, air, and gas. They are most commonly used in water supply and sewerage systems, and highly regarded for durability, safety, and reliability. They are also installed in a power, oil, gas, or chemical plant, and used as stop valves for hot and high-pressure steam or high-pressure gas. Therefore, there is enough variation to support special types, such as an explosion-proof type and a heat-resistant type.
