Festo
The Festo 8157911 is an industrial component of the MSE series in size 6, featuring a 2/2-way monostable open valve function with a mechanical spring reset and a normal nominal flow rate of 4500 l/min. This unit operates within a pressure range of 0.35 MPa to 1 MPa (3.5 bar to 10 bar / 50.75 psi to 145 psi) and a pressure regulation range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar / 36.25 psi to 145 psi), maintaining a maximum pressure hysteresis of 0.03 MPa (0.3 bar / 4.35 psi) at a 100% duty cycle. It requires a horizontal mounting position within +/- 5° and utilizes compressed air as per ISO 8573-1:2010 [7:4:4] without oil lubrication, while drawing a max load current consumption of 100 mA and a logic max current consumption of 270 mA. Certified with RCM and KC-EMV, and bearing CE and UKCA markings as per EU and UK EMC and RoHS directives, this part carries specific compliance standards.
