Fushiman PHP50 Pressure Reducing Valves (High-Pressure Gas Equipment Certified Product)
Manufacturer: Fushiman Co.,LTD.
Model: PHP50
| Model | Nominal Diameter | Primary Pressure | Secondary Pressure Range | Maximum Operating Temperature | Body Material | Connection |
|---|---|---|---|---|---|---|
| PHP50 | 25〜50 | MAX. 4.0MPa | 0.2～2.5MPa | 80℃ | SUS | Flange |
New Product
- High-capacity pressure reducing valve for high-pressure applications.
- Handles high differential pressure and large flow fluctuations.
- The valve is not damaged even if primary pressure is applied to the secondary side.
