How can we help?

Are electric actuators as reliable as existing pneumatic actuators?Arrow

Utilizing a roller screw drive train, the Tritex EVA exceeds ISO22153 class D performance with little to no maintenance, and will last for years. 

Are electric actuators more expensive than pneumatic actuators?Arrow

When comparing actuator price to actuator price this is true. But If you compare the entire system price of a no-emissions actuation solution to a pneumatic system, electric actuators can be the more cost-effective solution.

Are electric valve actuators suitable for critical applications requiring high-speed?Arrow

The Tritex EVA electric valve actuator is as fast as pneumatic actuators, opening and closing in as little as one second.
