UD Derivative Unit is a specific device to amplify the exhaust. The regulating system is specifically designed for modulation and allows an accurate tuning to maximize speed without compromising the stability of the actuator.
This product is designed to be used in modulating systems (amplification of positioner exhaust flow) and also for on/off systems.
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 costs, inventory and the shortened dimensions save space.
