Actuator operated shut-off valves

All of our seat valves are available fitted with actuators. In this case, the valve can be controlled from locations other than from the immediate vicinity of the valve.

The basic model is a shut-off valve with a gland seal, but case-specifically, such as for thermal oil applications, our product range also contains an actuator operated shut-off valve with a bellows seal.

Case-specific actuator

Valves can be equipped with pneumatic or electric actuators.

A pneumatic actuator is fast and less vibration sensitive as compared to an electric actuator, for example. In our seat-type valves, we mainly use the factory’s own actuators, so that we are able to dimension an actuator of exactly the correct size for each valve type.

We can deliver electric actuators for different voltages made by the valve manufacturers themselves or by other manufacturers such as AUMA, BERNARD or ROTORK.

ARI’s own PREMIO actuator has been dimensioned so that the force produced by the actuator corresponds precisely to the force required by the ARI valve. This will also yield clear price advantages.

A safety device is available for electric actuators that will close the valve during a power failure.

Position transmitters and limit switches are available as optional extras.
