Prop. Pressure Regulating Valve Series PR-U-OEM---Hoerbiger.com
A piezo valve is used as the pilot control element. The piezo valve generates a pilot pressure in the pilot chamber of the main valve proportional to the control voltage.
The supply for the piezo valve is tapped off from the control air connection 1 and passed through a pressure regurlator and filter.
Note:
The valve for the PR-U-OEM series fulfils the requirements for approval as an intrinsically saft device when used with an appropriate controller.

The operating voltage range of the
valve may fluctuate due to temper-
ature or longterm effects
