PCD–Dual Valve Absolute and Gauge Pressure Controllers
Fast-responding pressure or vacuum control for closed volumes
Control the absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) of gases or liquids in your process. Alicat’s PCD series dual-valve pressure controllers use two proportional valves to precisely control the pressure of gases within closed or dead-ended volumes. They achieve new setpoints rapidly and stay put, even in the face of uneven feed pressure or changing temperatures. We’ll use your application parameters to customize your valve and PID tuning to ensure that your controller delivers fast and stable control.
Fast & Accurate. Very fast valves and PID control algorithms hit pressure setpoints in milliseconds with NIST-traceable accuracy.
Connected. Easy integration into your digital industrial network with Ethernet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
Efficient. The dual-valve design incorporates a second proportional valve to exhaust excess pressure, but only when needed to maintain your setpoint. This eliminates the need to continuously bleed costly gas.
