PCD3–Dual Valve Absolute and Gauge Pressure Controllers with Remote Sensing
Closed-volume pressure or vacuum control, anywhere you need it
Measure absolute or gauge pressure at any point in your closed process volume, and control flow at a different point to ensure your pressure stays on target. Alicat’s PCD3 series dual-valve pressure controllers use two proportional valves to precisely control the pressure of gases within dead-ended volumes and physically isolates the pressure sensor from the valve and flow path so that you can control pressure exactly where you need it. This allows pressure control in areas where you cannot easily install a full pressure controller and reduces the effects of flow-induced pressure changes in high-flow applications. 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. Plumb the pressure sense port wherever you need to control pressure.
Alicat’s PCD3 series uses small proportional valves for control at lower flow rates and is suitable for use with non-corrosive gases.
