Control head for decentralised automation of ELEMENT process valves

The control head Type 8695 is designed for decentralized automation of ELEMENT Type 21xx pneumatic process valves with smaller orifice. The registration of the valve position is done through a contact-free analogue sensor element, which automatically recognises and saves the valve end position through the Teach-In function during start-up. The integrated pilot valve controls single or double-acting actuators.
