Festo
4414814
Selector valve VHEF-EST-B32-N18
The Festo 4414814 is a 20 mm wide, bistable 3/2-way industrial component featuring a plate seat structural design and direct manual control with a detenting override intended strictly for hand operation. This directly controlled valve delivers a normal nominal flow rate of 750 l/min through 1/8 NPT pneumatic working ports, operating across a pressure range of -0.095 MPa to 1 MPa with an adjustable exhaust air function and zero overlap lap. Rated for use in ATEX Zone 1, Zone 2, Zone 21, and Zone 22 hazardous environments, it utilizes a soft sealing principle and accommodates any mounting position while operating on compressed air conforming to ISO 8573-1:2010 [7:-:-].

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
