Festo VZXF-L-M22C-M-A-N114-310-M1-V4B2T-50-9 Angle Seat Valve

Festo VZXF Angle Seat Valve Overview

The Festo VZXF-L-M22C-M-A-N114-310-M1-V4B2T-50-9 is a pneumatically actuated poppet valve designed for line installation in industrial fluid control systems. It features a 31 mm nominal width and a Kv flow rate of 18.5 m3/h, suitable for managing compressed air and compatible gaseous media. The valve housing is constructed from cast stainless steel (1.4408) with PTFE spindle and seat seals for chemical resistance. It operates within a medium pressure range of 0 to 9 bar and requires a pilot pressure of 6 to 10 bar.

Suited For Pneumatic Process Control

This valve suits engineers building or maintaining automated pneumatic circuits where a 2/2-way, normally closed, monostable function is required. The NPT 1 1/4 threaded connection and G1/8 pilot port support standard industrial piping practices. Buyers needing a reversible flow path or integrated flow control on the exhaust should look elsewhere, as this model offers non-reversible flow above the seat and no exhaust throttling option. Applications requiring actuation voltages or electrical interfaces are not addressed by this purely pneumatic unit.

Sustained High-Temperature Operation

Under continuous duty, the valve handles media temperatures from -40 °C up to 200 °C and ambient conditions between -10 °C and 60 °C. The mechanical spring reset ensures reliable return to the closed position without external power during prolonged cycles. Soft sealing with PTFE maintains leakage integrity across the full temperature and pressure envelope (PN 40 rating). The RoHS-compliant construction and paint-wetting impairment substances note confirm suitability for sensitive manufacturing environments over long service intervals.
