Fire Fighting System Use Ductile Iron Slow Close Slient Check Valve
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
Most fire valves are connected with clamps, making the complex valve installation and pipeline connection process simple, fast, and convenient. Taking pipeline connection technology a big step forward.
8300X Series slow closing slient check valve is a common valve equipment in fire fighting system for prevention of water backflow in pipeline systems.
It adopts the principle of hydraulic slow closing, which controls the opening and closing of the valve through the pressure difference of the fluid itself. When the fluid flows normally in the pipeline, the valve is in an open state, allowing the fluid to pass through. Once the fluid flows in the opposite direction, the valve will immediately close to prevent backflow. When the valve is closed, the hydraulic slow closing device inside the valve plays a buffering role, avoiding the water hammer phenomenon that occurs when the valve is closed.

Product features:
1. The valve disc design of the slow closing check valve can effectively prevent medium backflow, thereby avoiding the reverse flow of medium in the pipeline.
2. The valve disc can slowly close when closed, avoiding the occurrence of water hammer and reducing pipeline vibration and noise.
3. The slow closing check valve has good sealing performance, which can ensure the sealing of the medium in the pipeline.
4. The flow channel design of this valve is reasonable and can ensure a large flow rate to pass through.
5. The 300X slow closing check valve has a relatively simple structure, reliable operation, long service life, and is relatively easy to maintain and repair.
