Free Floating Lever
Product Overview
The FTGS14 is a ball float steam trap featuring an austenitic stainless steel body and stainless steel working internals. It includes an integral automatic air venting facility via the BP99/32 capsule. Designed for flanged connections, it is ideal for applications requiring high corrosion resistance and reliable condensate drainage.
Key Features
- Corrosion Resistance: Austenitic stainless steel body (1.4308) and all stainless steel internals.
- Durable Cover: Electroless nickel-plated SG iron cover for enhanced erosion resistance.
- Integral Air Vent: Automatic air venting ensures quick start-up.
- Versatile Orientation: Available for horizontal flow (R-L or L-R) and vertical flow (FTGS14V).
Sizes and Pipe Connections
Available sizes: DN15, DN20, and DN25. Standard flange connections:
- EN 1092 PN16
- ASME (ANSI) 150
- JIS/KS 10
Pressure and Temperature Limits
The FTGS14 is designed for PN16 conditions.

Dimensions and Weights (approximate)
| Size | A (PN/ASME) | A (JIS/KS) | B | B1 | C | D | E | F | G | Weight (kg) |
|---|---|---|---|---|---|---|---|---|---|---|
| DN15 | 150 | 150 | 107 | 96 | 102 | 50 | 47 | 38 | 105 | 4.7 |
| DN20 | 150 | 150 | 107 | 96 | 102 | 53 | 47 | 38 | 105 | 5.2 |
| DN25 | 160 | 170 | 107 | 119 | 65 | 100 | 10 | 38 | 120 | 6.8 |
Optional Extras
- Steam Lock Release (SLR): Designated as 'C' (e.g., FTGS14-C). Prevents steam locking in applications like siphon drainage.
- Integral Strainer: Designated as 'X' (e.g., FTGS14X).
Installation and Maintenance
The FTGS14 must be installed with the direction of flow as indicated on the body. The arrow on the nameplate must point downwards to ensure the float arm rises and falls vertically. It can be maintained without disturbing the pipework.
Spare Parts
Available spare parts include:
- Maintenance kit (Main valve assembly, gaskets, air vent)
- Main valve assembly with float
- Air vent assembly
- SLR unit (for 'C' models)
How to Order
