Name: Festo 8177451 Shut-off valve VBOC-L2-P-M12-G18-E
Brand: Festo

Shut-off valve VBOC-L2-P-M12-G18-E

The Festo part number 8177451 is a pneumatic industrial component featuring a 2/2-way closed, monostable valve function with G1/8 pneumatic connections 1 and 2, external pilot air supply, and a mechanical spring reset method. Designed with welding spatter-resistant properties and an inductive measuring principle, it operates within a pressure range of 0.05 MPa to 1 MPa (0.5 bar to 10 bar) and an ambient temperature range of -5 °C to 60 °C using compressed air as per ISO 8573-1:2010 [7:4:4]. This screw-in component provides a nominal flow rate standardized according to ISO 8778 of 290 l/min and conforms to EU and UK EMC and RoHS directives with CE and UKCA markings.

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.
