These electro-pneumatic positioners are for integrated mounting on pneumatic control valves with single-acting or double-acting actuators. The control-valve systems can be used for a wide range of tasks in fluid technology and can be applied to any hygienic sanitary single-seat valve.
Charlotte, N.C.-based Bürkert Fluid Control Systems says what differentiates this positioner from the competition is that it registers the valve position without deterioration by means of a contact-free, analog position sensor. Control of a single or double-acting actuator is done without intrinsic compressed-air consumption.
Communication interfaces such as DeviceNet and analog, as well as binary feedback are available.
These electro-pneumatic positioners meet the tough requirements of hygienic process environments.
The control air-channel is actuator-integrated for air-usage efficiencies and longevity. Internal control air routing helps reduce actuator size and keeps out humid environment. No air bleeds at the rest position. Software function selection is easy, done either on a back-lit graphic keypad display or over a PC interface.
The housing is easy to clean and features proven electrical IP 67 protection and chemically resistant materials for use in hygienic processing in food, beverage and pharmaceutical industries.
