General Description

The NH90 Hydramotor Series of Linear Actuatorsfeatures 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).

Operating Ranges

Range (Stroke) Thrust(lbs)
0-3.5 in. (89mm) 1,500 (680kg)
0-3.5 in. (89mm) 3,000 (680kg)
0-4.0 in. (102mm) 4,000 (1,800kg)
The NH90 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.

Features

• Self contained, intrinsically fail safe, sealed unit; no external pressure lines required
• Self lubrication and fewer moving parts mean less maintenance and longer service life
• Modular design speeds service and maintenance
• Infinite resolution and precise repeatability
• ""Hard positioning"" eliminates the effects of pipeline pressure surges
• Stem adapters and couplings available for a wide range of applications
• Continuous duty cycle
• Proportional or on-off operation
