SUMMARY:  SYDZ.-1X

Add to Cart

The pressure pre-loading is only effective within the pressure range up to 20 bar. If the operating pressure in port P1 exceeds 30 bar, the preload valve (1) is completely opened. For limitation of the maximum pressure, a pressure relief valve (2) is integrated in the pump preload valve which is fixedly set at the factory (see ordering code). An integrated check valve (3) that may be available allows for the pressure control in the range < 20 bar.

Notice:

The pressure limiting function is a pure safety function and not suitable for continuous operation!

Upon commissioning, the system is to be bled.

Only for separate order of the pump preload valve

For applications outside these parameters, please consult us!
