Product introduction: The H41 flanged connection check valve for traditional domestic use has the disadvantages of bulkiness, large fluid resistance, high water hammer pressure when the valve is closed, difficult installation and maintenance, and short service life. The valve supply network has developed the wafer type check valve series, H71 wafer type lifting type ..
Product introduction: Lift check valve refers to a valve that automatically opens and closes the valve flap by relying on the flow of the medium itself. It is also known as a check valve, one-way valve, and reverse flow that rely on the weight of the valve disc and the pressure difference of the fluid to automatically prevent the fluid from flowing backward Valves, and back pressure valves. Non-return valve is an automatic valve, its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor ..
Check valve: Check valve is also called check valve or check valve, its role is to prevent the medium in the pipeline from flowing backward. The bottom valve of the pump suction is also a check valve. The opening and closing parts rely on the flow of the medium and the force to open or close by itself, and the valve to prevent the medium from flowing backward is called a check valve. Non-return valve is an automatic valve. It is mainly used for pipelines with unidirectional flow of medium. Only allowed ..
