Brand: Festo

Selector valve VHEF-ES-M52-M-N18

The Festo 4414808 is a 20 mm wide piston gate valve featuring a 5/2-way monostable configuration, direct manual actuation, and a mechanical spring reset. Delivering a normal nominal flow rate of 750 l/min through 1/8 NPT pneumatic working ports, this component operates across a pressure range of -0.095 MPa to 1 MPa with an adjustable exhaust air function and reversible flow direction. Certified for ATEX Zone 1, 2, 21, and 22 environments, it utilizes a soft sealing principle and operates on compressed air conforming to ISO 8573-1:2010 [7:-:-] with optional oil lubrication.

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.
