Technical parameter and material
inside nominal diameter: DN50—500
operating temperature: -15℃—135℃
nominal pressure: PN1.0Mpa/ PN1.6Mpa/ PN2.5Mpa
1. Valve clack is designed in shape of sub warhead. The valve body is designed in shape of waist drum. These kind of design helps improve the medium flow direction and reduce the flow resistance.
2. The valve is designed in shape of short structure. Even though its water head loss is larger than that of 200H, its volume is small and the price is low.
3. The structure is compact. Non-metal lubrication set is installed between the
guiding axle and guide frame. The valve clack move up and down flexibly. It won't lock during the process.
4. The skeleton rubber ring can be directly embedded in the valve body, avoiding being directly scoured. The service life is evidently prolonged. The product is thus endurable.
5. The start-up and shutdown process is short, effectively preventing water hammer.
6. It is applicable to drainage system and high-rise drainage system. It can be installed at the exit of the pump. If modified slightly, it could be applied as the water absorption bottom valve, but it is not applicable to sewage drainage.
