Product Introduction

This valve is mainly used at the outlet of industrial circulating water supply, urban water supply and drainage, and high-rise building pressurized water pumps. This product is equipped with a water hammer elimination device, which can be divided into a water pressure slow closing device and an oil pressure slow closing device. The former uses water (purified water) in the pipeline network as a damping medium to stop water backflow and eliminate water hammer to ensure the safe operation of the pipeline network; The latter uses ordinary engine oil as a damping medium, completely isolated from the medium in the pipeline network, neither polluting the water quality nor being affected by the water quality in the pipeline network. GYHH44X type is used for water purification media, while GYHH44Z type is used for source water and sewage media. For ease of installation, there are two installation forms available: vertical and horizontal.
