Product Description

Product Overview:
1, the main function of H41H Debiao lifting check valve is to prevent the backflow of the medium in the pipeline. The bottom valve of the water pump suction close also belongs to the check valve class. The opening and closing parts rely on the flow and force of the medium to open or close, to prevent the backflow of the medium of the valve is called the check valve. The check valve belongs to the automatic valve class, which is mainly used for the one-way flow of the medium on the pipeline, and only allows the medium to flow in one direction to prevent accidents.
2, the characteristics of the standard check valve: easy maintenance, smooth appearance, exquisite beauty, durable.
3, German standard check valve application: power station, natural gas, ammonia, freezing system, hot oil system, hot water.
4, German standard check valve valve standard: structure length standard: DIN3202; Flange standard: DIN2543-DIN2546; Valve test and inspection standard: DIN3230-75
