Asco General Controls AH90 and NH90 Actuators

The Asco General Controls AH90 / AH-90 and NH90 / NH-90 Hydramotors series are electro-hydraulic actuators. The actuators are widely used in nuclear power plant systems. They provide critical safety functions such as valve and damper operation. The Hydramotor AH90 / NH90 series are very reliable but regular maintenance and overhaul is very important.

Regular maintenance and repair of the Asco Hydramotor AH-90 / NH-90 series will significantly reduce certain problems that would otherwise cause a Rule infraction or shutdown. Itt Controls can deliver the necessary parts of the Asco hydramotor AH90/NH90 series and also can deliver the complete actuator.

The Asco AH90 and NH90 Hydramotor Series of Linear Actuators features a completely self-contained, hydraulic power system that has been integrally coupled to a hydraulic cylinder. The positive, firm positioning actuators are ideal for providing efficient and
precise linear control of valves, dampers, louvers, and a wide variety of other equipment requiring an operating thrust of up to 1,500 lbs. (680 kg), 3,000 lbs (1,360kg), or 4,000 lbs. (1,800 kg).

The Asco AH-90 and NH-90 Hydramotor Series of Linear Actuators is qualified as Class IE, safety related equipment for nuclear power generating stations in accordance with IEEE standards 323, 344, 382, and 627.

Other types of the Asco General Controls Hydramotor ah series are: Asco General Controls ah90, ah-90, ah91, ah-91, ah92, ah-92, ah93, ah-93, ah94, ah-94, ah95, ah-95, ah96, ah-96, ah97, ah-97, ah98, ah-98 and ah99, ah-99.

Other types of the Asco General Controls Hydramotor nh series are: General Controls nh90, nh-90, nh91, nh-91, nh92, nh-92, nh93, nh-93, nh94, nh-94, nh95, nh-95, nh96, nh-96, nh97, nh-97, nh98, nh-98 and nh99, nh-99.
