Zhengmao Valve Hammer Check Valve: A "Backflow Guard" for Pipelines, More Worry-Free with Floating Ball Valves
First, let's share some solid parameters with you: the valve body is made of cast iron, WCB carbon steel, or 304 stainless steel, which can be selected according to the medium. The nominal diameter ranges from DN50 to DN600, the nominal pressure can withstand 1.0MPa to 6.4MPa, and the working temperature range covers -20℃ to 425℃. It can remain stable whether transporting water, oil, or neutral gas. The most crucial part is the seating tightness: the test pressure reaches 1.1 times the nominal pressure, so there's never a need to worry about medium backflow. Unlike some check valves that stop sealing tightly after two months of use, our valve comes with complete material reports and test data, which can be used directly during project acceptance, saving a lot of trouble.
Then let's talk about the advantages in use: it operates by weight counterbalance and lever principle-no additional power is needed to open the valve; the medium can push it open, and it closes quickly and stably. The water hammer effect is much milder than that of ordinary check valves. A water plant customer once said that after installing this valve, pipeline vibration was reduced, and the service life of the pump was even extended. The disc has a streamlined design, which minimizes medium resistance without affecting pipeline flow. It also wears slowly, so there's no need to replace core components for 5 to 6 years. If precise on-off control is needed in the pipeline, matching it with our floating ball valve is perfect: the hammer check valve guards against backflow, and the floating ball valve handles on-off control. This combination is especially reliable in continuously operating systems like chemical plants and water supply facilities.
Now this valve is used in water transmission pipelines of water plants, raw material pipelines of chemical plants, and circulating water pipelines of power plants. For example, when a water plant delivers water, it prevents pipeline water from flowing back into the water pump; when a chemical plant transports solvents, it avoids medium flowing into other sections. The most reassuring part is the after-sales service: this hammer check valve comes with a one-year warranty. Whether you need a master to provide on-site guidance during installation or encounter minor problems later, just make a call, and someone will respond within 24 hours. Spare parts are also shipped quickly, so the pipeline won't be out of service for long.
