Double Door Check Valve Manufacturers

As the professional manufacture, we would like to provide you Hispeed® 300PSI Wet System Valve. We supply 300PSI Wet System Valve.The Wet System valve works as a check valve by preventing the reverse flow of water from the system piping to the water supply. The valve is trimmed with a water bypass line,which has an in-line swing check valve. The bypass line allows pressure surges to enter the system and to be trapped above the alarm check valve's clapper without the clapper lifting and causing false alarms.When significant flow of water occurs, such as from an open sprinkler, the valve's clapper lifts and allows water to enter the system. Simultaneously, water enters an intermediate chamber, which allows the water to activate an alarm either through a water motor alarm or through a water pressure alarm. These alarms continue to sound until the flow of water is stopped.We are expecting to become your long term partner in China.

We supply Hispeed® Ductile Iron Knife Gate Valve.Its application range is very wide, from coal mining in mines and power plants, slag discharge, slag discharge, to urban sewage treatment; from cement and paper mill slurry transportation to food, sanitation, medicine and other professional pipelines. The ultra-thin design of the Knife Gate Valve completely solves the ordinary gate valve, the slab gate valve, the ball valve, the globe valve, the regulating valve, the butterfly valve and the like with the advantages of small volume, light weight, small flow resistance, no slag accumulation, easy installation and easy disassemble. The flow resistance is large, occupying space, easy to accumulate slag, and difficult to install and maintain. Therefore, a large number of general-purpose cut-off gates and regulating gates are replaced by Knife Gate Valve. We are expecting to become your long term partner in China.
