BRAND: ArcaCATEGORY: Actuators

The Arca ARCADRIVE pneumatic actuator is a simple design with a robust rolling diaphragm makes suitable for all applications while ensuring hysteresis-free control across the entire actuating range. These pneumatic valve actuators can be opened or closed using spring force or instrument control air.

The actuator is field-reversible, making them very versatile and providing security for your investments. The integrated compression springs ensure that the pneumatic control actuator always adopts a defined fail position. This is accomplished with very short actuating times meaning that alongside their control tasks, Arca diaphragm actuators also play a key role in safeguarding your plant. Explosion protection is not an issue when configuring pneumatic diaphragm actuators. A host of accessories and options are available including a manual emergency override.

We provide full valve repair and reconditioning facilities in Secunda & Durban.
