Cartridge proportional valve, series CP

Compact Precision for Open-Loop Control

The Series CP proportional solenoid valves are a compact and highly responsive solution for applications requiring precise open-loop flow control. These 2/2-way normally closed valves, available in 16 mm and 20 mm sizes, are directly operated and designed with a cartridge-style body—ideal for integration close to workstations or within tight system layouts.

One of the key advantages of the CP series is its pressure-compensated version, which ensures consistent output flow regardless of fluctuations in the inlet pressure. This provides stable and accurate flow rates, even in dynamic operating conditions. Furthermore, these valves do not require a minimum working pressure, making them suitable for systems operating under vacuum conditions.

Their design is optimized to reduce friction and eliminate stick-slip effects, ensuring smooth modulation and low hysteresis throughout the control range. This makes them ideal for applications involving gas mixtures, and they are also suitable for use with oxygen, under proper safety conditions.

Key Features:

• Directly operated 2/2-way NC function
• Compact cartridge design (16 & 20 mm)
•  Pressure compensated version for precise flow control
• Suitable for vacuum operation
• Compatible with oxygen
• High flow capacity with low hysteresis

The Series CP valves are built for demanding industrial applications where space, precision, and control responsiveness matter. Whether you're optimizing gas flow in medical, analytical, or automation systems, the CP series offers a reliable and efficient solution.
