Thermodynamic Steam Trap
Model: BS19H-16/25 (threaded) · BS49H-16/25 (flanged)
Disc type · one moving part · steam mains & drip legs
The best-selling steam trap in Gaoshan’s line. It uses only one moving part — a hardened stainless steel disc that cycles open and closed on the Bernoulli fluid dynamic effect. No bellows, floats, or levers to wear out, so it holds up to water hammer and works in almost any mounting orientation.
Typical Industries
Steam mains & headers
Steam tracing lines
Outdoor steam piping
Petrochemical & refinery
Power generation
Specifications
| Pressure class | PN16 (1.6 MPa) / PN25 (2.5 MPa) |
| Max temperature | 250°C |
| Body material | WCB cast steel · stainless steel disc & seat |
| Connection | DN15–DN50, threaded (NPT/BSPT) or flanged (RF) |
| Discharge type | Intermittent — cycles several times per minute |
Free Float Ball Steam Trap
Model: CS11H (threaded) · CS41H (flanged) — PN16/PN25/PN40
Continuous discharge · high pressure to PN40
A precision-ground stainless steel float ball rises and falls with the condensate level, giving smooth, continuous drainage instead of intermittent cycling — no water accumulation, maximum heat transfer. The only Gaoshan trap series rated to PN40 (4.0 MPa) and 425°C, with a built-in Y-series air vent for both cold and hot non-condensable gases.
Typical Industries
Heat exchangers
Condensate recovery systems
Air heater coils
Sterilizers & autoclaves
High-pressure process steam
Specifications
| Pressure class | PN16 / PN25 / PN40 (up to 4.0 MPa) |
| Max temperature | 300°C (PN16) / 425°C (PN25 & PN40) |
| Body material | QT450-10 ductile iron (PN16) / WCB cast steel (PN25, PN40) |
| Connection | DN15–DN50, threaded (NPT/BSPT) or flanged (RF) |
| Discharge type | Continuous — modulated by float buoyancy |
Thermostatic Steam Trap
Model: S44F-16 (flanged) · S14F-16 (threaded)
Bellows type · lowest steam loss · freeze protection
A liquid-expansion bellows element senses condensate temperature and closes tight before live steam can escape — rated at ≤0.5% no-load steam loss, among the lowest in the industry. It stays open when cold, so the trap drains completely on shutdown and needs no extra freeze protection outdoors.
Typical Industries
Petrochemical & refinery
Rubber & tire manufacturing
Pharmaceutical production
HVAC steam heating
Food & beverage processing
