Type H44H, H44W PN16~PN63 steel swing check valves
Product description:
H44H, flanges H44W swing check valve for pressure - 29 ~ + 1.6 ~ 25 mpa working temperature 550 ℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as the pipeline under various working conditions, its main role is to prevent the backflow medium, to prevent the pump and its pattern in reverse driving voltage, and the discharge of the containers within the medium, suitable medium such as water, oil, steam, acid medium. Widely used in petroleum, chemical, pharmaceutical, fertilizer, power industry, low temperature and other conditions of the pipeline.
Structural features:
1, the product structure is compact and reasonable, reliable sealing, excellent performance.
2. Small size and light weight.
3. Wide application scope.
4, disc close fast, sensitive action.
5, small closing impact, not easy to produce water hammer phenomenon.
6. Unobstructed flow channel and small fluid resistance.
H44H, H44Y type swing steel stop return valve is on the line by the flow of the medium itself and automatically open and close the force, belongs to an automatic valve. The check valve is used in the pipeline system, its main function is to prevent the backflow of the medium, prevent the pump and its drive motor reverse, and the discharge of the medium in the container. The check valve can also be used to supply the auxiliary system in which the pressure may rise above the pressure of the main system.
Scope of use: the product can be used in petroleum, chemical and other industries.
Products conform to the standard: GB/T 12235
