Fire Fighting System Use Ductile Iron Energy-Saving Soundproof 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.
The H81X series energy-saving soundproof check valve disc adopts the central axis guidance at both ends of the inlet, which is flexible in opening and closing, accurate in positioning, and can be installed horizontally or vertically. The valve disc is spring loaded, and its rapid closing can effectively reduce water hammer pressure. The sealing surface adopts a combination sealing structure of O-ring elastic seal and metal hard seal, with good sealing performance and no noise when closed. It also has the characteristics of small volume, light weight, low fluid resistance, small structural length, fatigue resistance, and long service life. This valve can be installed at the outlet of the water pump in water supply and drainage, fire protection, and HVAC systems to prevent backflow of water and damage to the pump.

Product features:
1. Compact structure, the valve disc can be lifted and lowered flexibly without any locking phenomenon.
2. The skeleton type rubber sealing ring is directly embedded on the valve body, avoiding direct erosion of the sealing ring by the medium for a long time, significantly extending its service life, and being sturdy and durable.
3. The short opening and closing stroke of the valve disc can effectively prevent water hammer.
4. Suitable for fire fighting system, water supply and drainage systems, high-rise building pipe networks, can be installed at the outlet of pumps, with slight structural changes, can be used as a suction bottom valve, but not suitable for sewage pipe networks.
