Fushiman P260 Pressure Reducing Valves – Contained Trap
Manufacturer: Fushiman Co.,LTD.
Model: P260
| Model | Nominal Diameter (mm) | Primary Pressure | Secondary Set Pressure Range | Maximum Operating Temperature | Body Material | Connection |
|---|---|---|---|---|---|---|
| P260 (Built-in Trap) | 15〜80 | MAX. 1.0MPa | 0.03～0.8MPa | 220℃ | FC,FCD | Flange |
- The built-in trap quickly discharges steam condensate from the primary side of the pressure reducing valve.
- Eliminates the need for trap piping immediately before the pressure reducing valve.
- The trap uses a membrane, offering excellent pressure resistance and corrosion resistance, ensuring clear operation.
