MVG14HR

172,60 €

The pressure-relief valves belong to the group of pressure valves. The pressure-relief valves to avoid exceeding the maximum pressure permitted in the system. The valve sequence can generate a pressure difference constant between the inlet and outlet of the flow rate.

The type MV is a valve controlled directly which is cushioned series. For the operative relations have a special offer also variants without damping.

 

Properties and advantages:

 

■ Operating pressures up to 700 bar.

■ Various adjustment possibilities.

■ Multiple designs.

 

Areas of application:

 

■ Hydraulic systems in general.

■ Test benches.

■ Hydraulic tools.

 

 

Base model and size: MVG 14 H.

 

Pressure range (bar): 10 ... 400.

 

Flow rate (l/min): 8.
