No air-bleed controllerBurkert offers the Type 1067 PID Controller/Positioner, a no-air-bleed device compatible with virtually any rising-stem or quarter-turn valve/actuator used for process control. The unit consists of the valve stem position pickup and a microprocessor-driven pneumatic controller. A valve stem-mounted potentiometer provides precise valve position data for the units electronics. The controller provides the positioning, I/P transducer and PID control functions. Operation as a PID controller or positioning device is set internally; it may be adjusted via the integral display panel or sent remotely via common current (0-20 mA, 4-20 mA) or voltage (0-10VDC) signals. The unit can be mounted integral to the valve/actuator or remotely. http://www.burkert-usa.commarketing-usa@burkert.com
