Detailed introduction to High Pressure Check Valve:
High pressure check valve - also named clack valve, non-return valve or one-way valve - allows high pressure liquid or gas to flow through it in only one direction.
| FEATURES & BENEFITS Ball Seat Poppet Check Valve - Metal-to-metal seat for rapid cycling or severe environments Soft Seat Poppet Check Valve - O-ring seat for fast shut-off and reliable seal; standard material is Nitrile. A variety of seal materials are available for even the harshest media. |
| Working Pressure: | Up to 60,000 PSI (4140 bar) |
| Temperature Ratings: | Ball Seat Poppet -420° to 1200°F (-251° to 648°C) Soft Seat Poppet -65° to 250°F (-54° to 121°C) (with standard Nitrile seal) |
| Nominal Cracking Pressure: | 15 PSI (1 bar) Optional cracking pressures up to 100 PSI (7 bar) |
| End Connections: | Female NPT,H/P Cone & Thread |

液壓閥是一種用壓力油操作的自動化元件，它受配壓閥壓力油的控制，通常與電磁配壓閥組合使用，可用于遠距離控制水電站油、氣、水管路系統的通斷。常用于夾緊、控制、潤滑等油路。有直動型與先導型之分，多用先導型。
