About Proportional control valves
Proportional valves set pressure or flow continuously from an electrical setpoint instead of only switching between open and closed. The group covers nominal sizes DN 1.2 to 8 mm on G 1/8, G 1/4 and G 3/8 threads. Some valves control pressure across 0 to 10 bar, others control flow.
What matters when choosing
- Decide on the controlled variable first: the pressure regulators are 3-way designs rated for a working pressure of 0 to 10 bar, the flow regulators are normally closed and are sized via the maximum differential pressure.
- DN 1.2 to 8 mm together with the flow rate of 470, 780 or 1750 l/min. Nominal size governs how much air passes when the valve is open and therefore the dynamics of the control loop.
- Thread G 1/8, G 1/4 or G 3/8 to suit the existing pipework. Within this group the larger nominal sizes come with the larger threads.
- Medium: part of the range is released for air, neutral gases, water and oil, the rest for air or neutral gases only, filtered to 50 µm, lubricated or unlubricated.
- Seal material FKM or NBR and housing in brass, aluminium or PA. FKM widens media compatibility, the housing material follows the installation environment and the permitted medium temperature of -10 to 0 °C at the low end and 50 to 90 °C at the top.
Typical applications
- Electronic pressure control on test benches and measuring stations
- Force and clamping pressure control on pneumatic cylinders and fixtures
- Metering and flow control of air or neutral gases in process plant
- Control loops carrying water or oil where the selected version is released for it
- Setpoint driven systems with 24 V DC control and digital communication
Sealing is by FKM or NBR, housings are brass, aluminium or PA. Versions with a filter requirement need air preparation down to 50 µm, and production takes place in Germany, Poland, Hungary and the Netherlands.
