Festo
The Festo 1635983 is a directly controlled piston regulator featuring a 3 mm nominal width for both pressurization and exhaust, functioning as a 3-way proportional pressure control valve closed with a soft sealing principle. This component operates within an inlet pressure range of 0 bar to 50 bar and a pressure regulation range of 0.4 bar to 40 bar, incorporating an LED indicator display and a mechanical spring reset method with reverse polarity protection for all electrical connections. Safety instructions specify that if the power supply cable breaks, the outlet pressure will drop to 0 bar, and the valve maintains a maximum pressure hysteresis of 0.4 bar.
