Festo
The Festo part number 8031109 is a 3-way proportional pressure control valve featuring a pilot-controlled diaphragm regulator, soft sealing principle, and a nominal pressurization width of 6 mm with a 4.5 mm exhaust nominal width. This electrical component provides a pressure regulation range of 0.01 MPa to 1 MPa (0.1 bar to 10 bar) and supports a normal nominal flow rate of 1400 l/min based on DIN 1343, operating on an 18 V to 30 V DC voltage range with short-circuit and reverse polarity protection across all electrical connections. Safety instructions dictate that if the supply cable breaks, the outlet pressure is maintained in uncontrolled form. Submit the exact part number, quantity, and application requirements for a quote.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
