PCDS–Series: Anti-Corrosive Dual Valve Differential Pressure Controllers
PCDS-Series Anti-Corrosive Dual Valve Differential Pressure Controllers use two proportional valves to maintain differential pressure between any two points in processes flowing corrosive gases within dead-ended volumes.
- Aggressive gas compatibility. Wetted materials compatible with many pure corrosive gases and most refrigerant gases, in addition to all non-corrosive gases and a variety of liquids.
- Fast & accurate. Custom valve sizing and PID tuning ensure controllers reach pressure setpoints in milliseconds and maintain control with NIST-traceable accuracy to ±0.125% of full scale.
- Efficient, versatile control. Maintain differential pressure between any two points or keep one port open to atmosphere and control gauge pressure, with readings displayed in your choice of engineering units. Additionally, the second proportional valve exhausts excess pressure only when needed to maintain your setpoint, eliminating the need to continuously bleed costly gas.
- Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.
