Actuator operated shut-off valves

All our seat valves are available fitted with actuators. In this case, the valve can be controlled from other places 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 with an electrical actuator. In our seat type valves we use the factory’s own actuators, so we are able to dimension a correctly sized actuator for each valve type.

We can deliver electrical actuators for different voltages made by 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 give clear price advantage.

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

Position transmitters and limit switches are available as optional extras.
