Festo
The Festo 8157909 is a size 6 industrial component of the MSE series featuring a 2/2-way monostable open valve function with a mechanical spring reset method and a horizontal +/- 5° mounting position. This unit operates within a pressure range of 0.5 MPa to 1.1 MPa (5 bar to 11 bar, 72.5 psi to 159.5 psi) and a regulation range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar, 36.25 psi to 145 psi) with a maximum pressure hysteresis of 0.03 MPa (0.3 bar, 4.35 psi). Delivering a normal nominal flow rate of 7000 l/min using compressed air as per ISO 8573-1:2010 [7:4:4], the device supports a 100% duty cycle, a max load current consumption of 260 mA, a logic max current consumption of 320 mA, and a max residual current of 1 A while carrying RCM, KC-EMV, CE, and UKCA compliance markings.
