From Burkert USA, PI controllers Type 8623-2, 8624-2 and 8625-2 can be mounted to the company's 1" solenoid valves or any DIN 43 650-A compatible proportional solenoid valve. The units provide continuous control of level, flow, temperature or pressure in liquids and gases and accept industry-standard signals directly from process sensors to provide control loop solutions. Setpoints can be set locally or remotely via the device's standard 4 to 20 mA or 0 to 10 V external signal input.
