Flow rate Qmax: 22 l/min

More details...


275,45 €

The for pressure regulating valves belong to the group of pressure valves. Maintain nearly constant outlet pressure even when inlet pressure has changed and has increased.

Valve type CDK can be threaded onto and incorporate into blocks of command. The holes of the housing are easily confeccionables. All the versions are watertight and are exempt from the oil recovery when they are closed.

Properties and advantages:

■ Water-resistant and oil-free recovery in the closed state.

Areas of application:

■ Hydraulic systems in general.

■ Devices.

■ Test benches.
