H42Y / W High Pressure Vertical Check Valve

H42Y / W high pressure vertical check valve structure
H42Y / W high pressure vertical check valve structure

H42Y / W high pressure vertical check valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, the spring resistance is overcome to make the valve open. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core toward the valve seat to close the valve, preventing the medium from flowing backward, so it acts as a check.

Structural features

1.The upper and lower valve bodies are connected by flanges
2. The manufacturing and acceptance conditions are in accordance with the provisions of JB450.
3. The sealing surface of the valve disc and the valve seat is made of stellite cobalt-based hard alloy, which is hard-wearing, high-temperature-resistant, corrosion-resistant, good abrasion resistance and long service life.
4. The high-temperature and pressure-resistant parts are made of high-quality heat-resistant alloy steel, which is safe and reliable, stable in performance and long in service life. High-pressure lifting check valves have been widely used in high-pressure pipelines in various chemical, metallurgical, and steel industries.
