Festo
161979
Proportional directional control valve MPYE-5-1/8-HF-420-B
The Festo 161979 is an electrical piston gate valve featuring a 6 mm nominal width, hard sealing principle, and any mounting position. Operating at 0 to 1 MPa with a 5/3-way closed valve function, it delivers a normal nominal flow rate of 700 l/min alongside a 95 Hz cut-off frequency and 4–20 mA setpoint/actual values. Utilizing a magnetic spring reset method and direct control, this component approaches a blocked mid-position upon power supply cable breakage based on its safety instructions.

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.
