Product Details
Product Introduction:
The H44W check valve is generally installed in vertical pipelines. Install the arrow mark upwards and use the medium to flush the valve disc from bottom to top, allowing the medium to circulate. When the medium stops, the valve disc falls by its own weight to close the valve, or it can be closed downwards through the return medium valve disc.
Working principle:
The H44W vertical check valve is normally closed, but due to the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance and causes the valve to open. When the pressure of the medium at the inlet end is lower than that at the outlet end, the spring pushes the valve core towards the valve seat, causing the valve to close and preventing the medium from flowing back, thus acting as a check.
Product features:
1. The valve disc rotates around the pin axis outside the valve seat to reduce violent impact during closure.
2. The product design and manufacturing comply with GB12236 design standards, with a reasonable structure, reliable sealing, and beautiful appearance.
3. The pin shaft is connected to the valve disc using an internal pin shaft structure, reducing external leakage points and making it more reliable to use.
4. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
5. The sealing surfaces of the valve disc and valve seat are made of hard alloy overlay welding, which is wear-resistant, high-temperature resistant, with good scratch resistance and long service life.
6. The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
