Description
The integrated pilot valve controls single or double-acting actuators. One of three communication interfaces can be selected as an option, namely AS-Interface, IO-Link or büS, which is based on CANopen. The pilot air duct runs inside the head and the actuator, with no external piping. Besides the electrical position signal, powerful coloured LEDs on the housing show the device status, even in difficult ambient conditions. The housing is easy to clean and has proven IP protection and chemically resistant materials for food, beverage and pharmaceutical processing. The head is aimed at plants that are regularly washed down, so it can be installed without worry about moisture.
How to choose
Start with the valve, because the 8691 is made for ELEMENT 21xx pneumatic valves. Then pick the interface already present on the plant network, AS-Interface, IO-Link or büS, or go without one if the electrical position signal is enough. For valves of other series, look at the universal control head for hygienic process valves.
