Festo
193251
On/off valve HEP-3/8-D-MIDI
The Festo 193251 is a pneumatic industrial component featuring a piston gate valve structural design with a soft sealing principle and a 3/2-way, closed, monostable valve function. It operates within a pressure range of 0 MPa to 1.6 MPa, utilizes a mechanical spring reset method, and delivers a normal nominal flow rate of 3500 l/min for compressed air and inert gases. Designed with in-line installation or accessory mounting capabilities, this RoHS-compliant unit operates across a temperature range of -10 °C to 60 °C and exhibits a moderate corrosion stress resistance class of CRC 2.

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.
