High-temperature nickel alloy check valves

Detailed product information

♦ Product characteristics: To ensure high requirements for tightness, reliability, and safety of the valve, the body is manufactured using solid forging or forging with welding from nickel alloy. The sealing surfaces are hard alloyed to increase wear resistance and scratch resistance, which extends the service life of the seal. The self-sealing center cavity design ensures reliable sealing under high pressure—the higher the pressure, the better the seal.

♦ Application: The product is designed for use in the petrochemical and oil refining industries under high temperature, pressure, and aggressive environments.
