Roll Grooving Machines(Auto Operated) 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® Sludge Drainage Valve.Double chambers diaphragm actuated, without physical friction, last a long service life. The HISPEED® Sludge Drainage Valve is usually installed at the bottom outside wall of the precipitation pool.We are expecting to become your long term partner in China.

We supply Nozzles and Open Sprinklers.The HISPEED® Nozzles and Open Sprinklers are discharge devices used as part of deluge systems to protect high-hazard areas such as tunnels, oil refineries, chemical facilities, offshore platforms, and power plants. These locations frequently contain highly flammable, combustible, or explosive materials that require robust fire protection systems. The HISPEED® Nozzles and Open Sprinklers provide water flow that is controlled manually or through quick opening valves that are pneumatically, hydraulically, or electrically activated. We are expecting to become your long term partner in China.

As the professional manufacture, we would like to provide you high quality Hispeed® PN16 Resilient-Seated Swing Check Valve. We supply PN16 Resilient-Seated Swing Check Valve.The Check Valves are low friction loss check valves designed for use in fire protection systems. These are used in fire protection systems to allow water-flow in one direction only. Typical applications include connections between public water supplies and private fire systems, at the discharge from fire pumps, at gravity tank connections and at fire department pumper connections.We are expecting to become your long term partner in China.
