Festo
8181686
Proportional-pressure control valve VPPE-3-1-1/4-2-420-E1-F1A
The Festo part number 8181686 is a pilot-controlled diaphragm regulator featuring a 3-way proportional pressure control valve with electrical actuation and soft sealing. It operates within a pressure regulation range of 0.02 bar to 2 bar (0.002 MPa to 0.2 MPa), an inlet pressure of 3 bar to 4 bar (0.3 MPa to 0.4 MPa), a nominal pressurization width of 5 mm, an exhaust nominal width of 2.5 mm, and a normal nominal flow rate of 700 l/min at a DC operating voltage range of 21.6 V to 26.4 V. Additional technical characteristics include a mechanical spring reset method, piloted control, a 3-digit LED display indicator, short-circuit and reverse polarity protection for all electrical connections, and a VPPE safety position maintaining outlet pressure in uncontrolled form if the supply cable breaks.
