Festo
186514
On/off valve HE-1/2-D-MAXI
The Festo 186514 is a manually actuated piston gate valve featuring a soft sealing principle and a 3/2-way, bistable valve function with a non-reversible flow direction. This component operates across a pressure range of 0 MPa to 1.6 MPa (0 bar to 16 bar) and a medium and ambient temperature range of -10 °C to 60 °C, delivering a normal nominal flow rate of 5600 l/min with compressed air or inert gases. Designed with a CRC 2 corrosion resistance class, it allows for in-line installation or mounting with accessories in any position, and requires oil lubrication for continued operation.

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.
