RTC

Scotch yoke pneumatic actuators

The RTC single/double acting pneumatic low-pressure actuators, are suitable for the operation of quarter turn valves (ball valves, butterfly valves and plug valves) for on-off and modulating heavy duty service. L'attuatore è costituito da un dispositivo a glifo che trasforma il movimento lineare del cilindro pneumatico (al momento della chiusura o dell'apertura) nel movimento rotatorio necessario per azionare la valvola.
