Brand: Festo

Soft-start valve VABF-S6-1-P5A4S1YE-G12-1T1L-PZ

The Festo 40 mm piston gate valve (Part Number 8161609) is an electrically actuated industrial component featuring a soft sealing principle, piloted control with an internal pilot air supply port, and a non-reversible flow direction. Designed with a mechanical spring reset method, negative overlap, and a valve function for pressurization and exhaust, it supports both detenting and self-resetting manual overrides via an electrical control signal, alongside an NC contact switching element function. This unit accommodates any mounting position and withstands vibration and shock according to severity level 2 standards per EN 60068-2-6 and EN 60068-2-27, while tolerating a max. positive test pulse with 0 signal of 2000 µs and a max. negative test pulse on 1 signal of 1200 µs.

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.

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.
