UD Derivative Unit

Actuation Accessories

The Derivative Unit (model UD) is a specific device to amplify the exhaust. The regulating system is specifically designed for modulation and allows an accurate calibration (tuning) to maximize speed without compromising the stability of the actuator. Designed to be used with precision and easy tuning in control systems (amplification of exhaust positioner flow) and also for on/off systems.

Exclusive manifold mounting system. It is a special IMI STI application to connect our accessories. Fittings or nipples are not necessary as the connection is achieved using machined connection faces with sealing ‘o’ ring. This system saves time for assembly, reduces cost on items such as fittings, reducing inventory and the shortened dimensions save space.

• Standard, offshore, sandstorm, copper free ambient condition.
• Single and double acting actuators.
• Low and high ambient temperature.
