Pneumatic valve VL-5/2-1/8-P-B

The Festo 173170 is a 5/2 monostable industrial component utilizing a piston slide design structure with a soft sealing principle and positive overlap lap. This pneumatically actuated valve features a 17.8 mm width, an 18 mm grid dimension, a 5 mm nominal size, and a standard nominal flow rate of 600 l/min with a b value of 0.36. Operating within a working pressure range of -0.9 to 10 bar and a pilot pressure of 2.5 to 8 bar, it includes mechanical spring reset, throttleable exhaust-air function, external pilot air supply, direct piloting, and reversible flow direction for any assembly position, backed by UL recognized authorization.

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. 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
