Festo
1635978
Proportional pressure control valve VPPL-3Q-3-0L40H-V1-V-S1-1
The Festo 1635978 is a directly controlled piston regulator featuring an electrical actuation type and a 3-way proportional pressure control valve closed function with a soft sealing principle. It delivers a pressure regulation range of 0.4 bar to 40 bar (0.04 MPa to 4 MPa) and an inlet pressure range up to 50 bar (5 MPa), incorporating reverse polarity protection for all electrical connections and an LED indicator display type. Built with a 3 mm nominal width for both pressurization and exhaust, this unit operates with a mechanical spring reset method, a maximum pressure hysteresis of 0.4 bar (0.04 MPa), and a safety function where a broken power supply cable causes the outlet pressure to drop to 0 bar.

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.
