"Automatic Sprinkler Systems Part 17: Pressure Reducing Valves" released by the National Standard

The National Standards Committee issued the No. 10 announcement on July 20, 2011, approving the release of GB5135.17-2011 "Automatic Sprinkler Systems Part 17: Pressure Reducing Valves", which is a mandatory national standard and will be published in 2011. It will be implemented on November 1.

GB5135.17-2011 specifies the classification, requirements, test methods, inspection rules, signs, packaging, transportation and storage of automatic fire extinguishing system pressure relief valves. It is suitable for direct acting and pilot operated pressure reducing valves in sprinkler systems.

Relief valve is the automatic sprinkler system, through its own structural components to achieve the outlet pressure when the inlet pressure and flow rate change to a certain outlet pressure valve. With the rapid development of the national economy, more and more high-rise buildings and other multi-functional and complex buildings are also used. The pressure reducing valve serves as a pressure-reducing control valve for the partitioned water supply to equalize different differential pressures and flow rates. Extensive, role is also more and more important. This standard provides a unified stipulation on the structural components, materials, strength sealing, decompression performance, and work reliability performance of pressure reducing valve products, which will help improve the overall quality level of the product.

The standard was drafted by the Tianjin Fire Research Institute of the Ministry of Public Security. The implementation of the standard will provide a basis for the production of direct acting and pilot operated pressure reducing valves in China's automatic sprinkler systems, facilitating the design, use, and maintenance of the product and playing an important role in the stable operation of the protection system.

Electric Stacker:


We manufacture Compact Electric Stacker and full electric Stacker for market demands. Our Narrow Aisle Electric Stacker has side-driven design and maintenance free battery. It is a great walk behind forklift. Our straddle electric stacker is our client`s favorite. This ride-on electric stacker has AC brushless motor which provides more power and less maintenance required. Akodi also supplies best value counterbalance electric forklift.
