Angle seat valve for pneumatic control
The Festo VZXF poppet valve uses a pneumatic piston actuator to open and close a 2/2-way circuit. It mounts directly in a pipeline with internal G1/2 threads and a G1/8 control port. The monostable design returns to the closed position by mechanical spring when pilot pressure is removed. Suitable for compressed air systems that follow ISO 8573-1:2010 quality class 7:4:4.
Pressure and flow limits defined by the standard
The valve body is rated PN 16 and handles medium pressures from 0 to 16 bar. Pilot pressure must stay between 6 and 10 bar for reliable actuation. Flow capacity is Kv 3.7 m3/h in the under-seat direction for gaseous or liquid media. Medium temperature range spans -40 °C to 200 °C while ambient temperature must remain between -10 °C and 60 °C.
Red brass housing with PTFE seals for durability
The valve housing uses red brass material CC499K with spindle and seat seals made from PTFE. This combination resists paint-wetting impairment substances and meets RoHS requirements. Line installation allows any mounting position. The threaded sleeve connection follows DIN ISO 228. Unit weight is 1200 g supplied in a single box.

Questions about this item
Should I choose the G1/2 12 mm version or a different port size for my pneumatic line?
The valve is built with a G1/2 threaded sleeve per DIN ISO 228 and a 12 mm nominal width; select this version when your piping matches those dimensions and you need the 3.7 m³/h Kv flow rate.
What does the 3.7 m³/h Kv value mean once the valve is installed in my system?
It indicates the water flow in cubic metres per hour at a 1 bar pressure drop; with compressed air at 6–10 bar operating pressure the actual throughput will be higher, but the Kv remains the sizing reference.
The pneumatic connection is G1/8 — what does that cap in practice?
The G1/8 internal thread limits the pilot air supply line to that port size, so the external control tubing or fitting must match G1/8; it does not restrict the main G1/2 process flow.
