TORK SR Series Single Acting Pneumatic Actuators

Why Use Single Acting Pneumatic Actuator?

• The preferred actuator type is the single acting actuators (spring return actuators) where the valve is requested to return to the first position when the power is cut. The spring return actuator is generally preferred in systems requiring safety.

ion of spring return actuator:

The torque values of the ed actuator at P: 6 bar control pressure are given in Nm. In this table, according to the ed values of the ed model (according to 90º) Nm values of the appropriate valve should be ed.

Note: Please refer to the values in the above table when ing the valve for the actuator. The torque of the valve must be 25% less than the actuator torque.

Actuator:

• 0º: start, closed position actuator

• 90º: End, open position actuator

Spring:

• 0º: Spring mounting position

• 90º: Release position compression

• 1 bar: 14.5 PSI; 1 Nm: 8.85 LB-in; 1 Kgm: 9,81 Nm
