200X 型水用减压阀：法兰连接形式、弹簧薄膜式结构、密封面材料为丁腈橡胶铜合金、公称压力 PN10-PN25、阀体材料为灰铸铁或球墨铸铁的减压阀。
200X Water pressure reducing valve： Flange connected, Spring film structure, nitrile rubber copper alloy for sealing surface material, Nominal Pressure PN10-PN25, gray cast iron or Nodular cast iron for Valve body material of Pressure reducing valve.
The product design against for high-rise, super high-rise building, it is an idea product to solve the water demands in households in high-rise building and fire water system, the requirements of big flow, high sensitivity and such occasions. water,. Its performance is more superior, could completely replace the intermediate water tank, and save costs of intermediate water tank of building, and expand the use area of the building.
3. 进出口压力应不小于 0.2MPa，小 0.2MPa 稳压性能变差。
1.It is recommended to install exhaust valve in the pipe network system in order to make pressure reducing valve work stability.
2.When install the valve, should pay attention to the arrow of flow direction, for the convenience of maintenance,3. Import and export pressure should not be less than 0.2 MPa, 0.2 MPa regulated performance becomes poor.
3. Inlet and outlet pressure should not be less than 0.2MPa, steady pressure will deviated when pressure less than 0.2Mpa.
