On/off valve MS4N-EE-1/8-10V24-Z

The Festo 542591 is an electrically actuated piston gate valve featuring a 3/2-way, closed, monostable function with piloted control and a non-detenting manual override. It operates within a pressure range of 4 bar to 10 bar, providing a normal nominal flow rate of 1000 l/min, a C value of 4.5 l/sbar, a b-value of 0.5, and mechanical spring reset. The unit utilizes a 24 V DC, 1.8 W coil, supports a 100% duty cycle, and functions with compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases within a medium temperature range of -10 °C to 50 °C.

Why no listed price?

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.
