Festo
187333
Proportional pressure control valve MPPES-3-1/4-10-010
The Festo part number 187333 is an electrical, pilot-controlled piston control valve featuring a soft sealing principle and a 3-way proportional pressure control valve closed function with a nominal width pressurization and exhaust of 7 mm. Operating at a DC operating voltage range of 18 V to 30 V with a 24 V nominal operating voltage DC, this component includes short-circuit and reverse polarity protection for all electrical connections, an operating pressure of 1.2 MPa (12 bar), an inlet pressure 1 ranging from 11 bar to 12 bar (1.1 MPa to 1.2 MPa), and a pressure regulation range of 0 bar to 10 bar (0 MPa to 1 MPa). It provides a maximum pressure hysteresis of 0.005 MPa (0.05 bar), an on switching time of 200 ms, a switching time off of 360 ms, and can be mounted in any position while adhering to safety instructions where a power supply cable break causes the outlet pressure to drop to 0 bar.
