Designed for its location
ANSI or PN flanges of any rating, in a standard length or custom up to 500 mm.
Removable body
High integrity strainer. The body comes out for maintenance without removing the whole assembly.
Welded and tested to ASME
Manufactured and tested to ASME standards.
Shell and tube heat exchangers
Condensate discharge from the steam side under variable load.
Air heaters
Steam coils and batteries heating process air.
Calorifiers and reboilers
Process equipment with variable steam demand.
Cooking vessels
Jacketed vessels with heating cycles.
Compare the connections
The versions share the design and main components. The connection changes, and with it the operating limits.

Frequently asked questions
What maintenance and engineering teams ask us most about the VFP trap.
What applications is the Fenix VFP steam trap designed for?
Process applications such as shell and tube heat exchangers, air heaters, calorifiers and cooking vessels, on flanged lines.
What is the maximum operating pressure of the VFP?
VFP: depends on the flange rating, from PN16 or ANSI 150 up to PN100 or ANSI 1500.
What sizes and connections does the VFP come in?
½" (DN15), ¾" (DN20), 1" (DN25). Connections: ANSI or PN flanges.
How is the VFP maintained?
The trap body can be removed for maintenance without removing the whole assembly from the pipework. The optional drain valve allows periodic strainer cleaning.
Can the VFP be made in a special length?
Yes. The standard length is 305 mm (12") and it can be made to measure up to 500 mm (20").
What warranty does the Fenix VFP trap have?
The Fenix VFP trap has a 15-year warranty. Its strainer, designed and made by Fenix, is also guaranteed for 15 years.
Why does the trap strainer matter?
Particles carried by the steam, such as rust, weld slag and scale, can block the nozzle. A robust, efficient strainer keeps the trap working properly. That is why Fenix designed and makes its own strainer and guarantees it for 15 years.
What is the drain valve for?
It is an optional accessory that allows easy strainer cleaning. When opened, line pressure blows out the sediment held in the screen without opening the cap. It is recommended for traps operating at no more than 20 barg.
What spare parts are available for the VFP?
Cap gasket (G-4), Flange gasket (G-8), Nozzle gasket (G-3).
Fenix strainer, designed and made by Fenix
A trap only works well if the condensate reaching it is clean. That is why Fenix designed and makes its own strainer, and guarantees it for 15 years, the same as the trap.
Protects the nozzle and venturis
Rust, weld slag and scale carried by the steam are among the most common causes of trap failure. The strainer holds them back before they reach the nozzle.
Robust by design
High integrity strainer: CF8M cast body and 40 mesh stainless steel screen with 10 mesh reinforcement. 304L stainless steel cap.
Cleaning without removing the trap
The screen comes out through its cap; the trap body stays installed in the line.
Optional drain valve
An accessory that allows easy strainer cleaning: when opened, line pressure blows out the sediment held in the screen without opening the cap. Recommended for traps operating at no more than 20 barg.
Trap and strainer from one maker
Both are designed and made by Fenix, and both carry a 15-year warranty. No generic third-party strainer.
