1, in order to facilitate the operation and maintenance, the valve installed in the level normally upright pipe. 2, the installation media should pay attention to the flow of the pipeline and the valve closing direction of the arrow shown on the line. 3, in order to prevent over-pressure valve after the pressure should be at least 4M away from the exit valve to install a pressure reducing valve. Valve function and use: 200X pressure reducing valve is a kind of energy to the use of media self-regulation and control of intelligent piping pressure valve. For the life of water supply, fire water supply and other industrial water supply system, through the decompression valve guide valve, you can adjust the main valve outlet pressure. Outlet pressure is not due to inlet pressure, flow of imports and change, safe and reliable way to maintain the set outlet pressure will be planted, and can adjust settings as needed to achieve the purpose of decompression. The decompression valve precision, stable performance, safe, reliable, easy to install adjustable, long service life. Regulator Technical Data: 1, Nominal pressure: 1.0MPa, 1.6MPa, 2.5MPa 2, shell test pressure: P = 1.5PN 3. Sealing test pressure: P = 1.1PN 4, outlet pressure: PN1.0MPa valve 0.09 ~ 0.8MPa PN1.6MPa regulating valve 0.10 ~ 1.2MPa PN2.5MPa regulating valve 0.15 ~ 1.6MPa 5, suitable medium: water 6, suitable temperature: 0 ℃ ~ 80 ℃ The main control valve fixed the main valve outlet pressure, the main valve outlet pressure does not change due to changes in inlet pressure is not due to changes in export flows the main valve to change its output pressure. Applies to industrial water supply, fire water supply and water distribution network systems used in daily life.
