Actuators

The principle part, equivalent to the valve body, of the control valve is an actuator. Either globe type or rotary type valve requires the actuator which precisely working by input signal. A spring return diaphragm type actuator is the principle product and cylinder or electrical type are also available.

Diaphragm Actuator for Rotary Valve

 
Model 2900 type
Diaphragm Actuator for Rotary Valve

Taking the advantage of single-spring diaphragm type, it is developed solely for the rotary type valves. High torque and reliability with compact in size.

 

Cylinder type for globe valve

Cylinder type for rotary valve

Model 1500 type
(Single Acting)
Model 1600 type
(Double Acting)
Model PM type
Cylinder type for globe valve Cylinder type for rotary valve

‘Single Acting’ cylinder type has a spring and ‘Double Acting’ has no spring. Required to select either type by operating conditions in case of emergency. Cylinder type is suitable for requirement of high torque or long stroke.

Cylinder type actuator shall be applicable in case high torque required. Both the single acting or double acting is available. For rotary type valve, it is common to apply the cylinder type actuator.
