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. For toxic media, DESCOTE seat valves with bellows are available.
For emergency shut-off applications, our range includes KÜHME emergency shut-off valves (under the Gas and fuel section).
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 also supply valves with actuators from other manufacturers.
Electric actuators from other manufacturers such as AUMA, BERNARD or ROTORK are available for operation at the voltages required.
ARI’s own PREMIO actuators are dimensioned so that the force produced by the actuators corresponds precisely to the force required by the ARI valve. This delivers evident price advantages.
Actuators are available with a safety function that opens or closes the valve in the case of compressed air or power supply failure.
Position transmitters and limit switches are available as optional extras.
