Festo
The Festo 1635973 is a 3-way proportional pressure control valve closed featuring a directly controlled piston regulator, an electrical actuation type, and a soft sealing principle. It offers a 3 mm nominal width for both pressurization and exhaust, operates at an inlet pressure up to 50 bar (5 MPa) with a pressure regulation range of 0.4 bar to 40 bar (0.04 MPa to 4 MPa), and incorporates a mechanical spring reset method along with an LED display indicator. Safety features include a VPPL safety position where outlet pressure drops to 0 bar if the power supply cable breaks, complemented by reverse polarity protection for all electrical connections and a maximum cable length of 30 m.
