Festo
187330
Proportional pressure control valve MPPES-3-1/2-6-010
The Festo part number 187330 is an electrically actuated, pilot-controlled piston control valve featuring a 3-way proportional pressure control function with a closed design and soft sealing principle. It operates on a nominal DC voltage of 24 V within a voltage range of 18 V to 30 V, incorporating short-circuit and reverse polarity protection for all electrical connections. The unit delivers a pressure regulation range of 0 bar to 6 bar (0 MPa to 0.6 MPa) at inlet pressures between 7 bar and 8 bar, while maintaining a maximum pressure hysteresis of 0.05 bar (0.005 MPa), an 11 mm pressurization nominal width, and a 12 mm exhaust nominal width. Safety features dictate that a power supply cable break causes the outlet pressure to drop to 0 bar, and the valve can be mounted in any position with an on switching time of 230 ms and an off switching time of 660 ms.
