H64Y / H national standard power station check valve

H64Y / H National Standard Power Station Check Valve Structure
H64Y / H National Standard Power Station Check Valve Structure

Scope of application

H64Y / H national standard power station check valve is suitable for pipelines with various working conditions such as nominal pressure PN1.6 ~ 16.0MPa and working temperature -29 ~ 550 ℃. Applicable media: water, oil, steam, acid media, etc.

Structural features

1. The product is designed and manufactured according to national standard GB12236, with reasonable structure, reliable seal and excellent performance.
2. The sealing surface of the valve flap and valve seat is made of iron-based alloy or stellite cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, good anti-scratch performance, and long service life.
3. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
4. The valve body has a complete range of materials. The packing and gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
5. The valve disc rotates around the pin outside the valve seat to reduce violent impact when closing.
6. The connection between the pin and the valve disc adopts a built-in structure, there is no external leakage point, and the use is more reliable.
