The 200X pressure reducing and regulating valve is composed of a main valve, a pilot valve, a needle valve, a ball valve, a micro filter and a pressure gauge to form a hydraulic control takeover system. When in use, when the outlet pressure is adjusted, it can automatically maintain a stable outlet pressure. This product is self-controlled by pilot valve, does not require other devices and energy, is easy to maintain, has high pressure control accuracy, is less affected by inlet pressure and flow, and is reliable in pressure reduction and regulation.
Introduction
200X pressure reducing valve is a valve used to adjust the direction of water supply in a water supply system in which fire water and domestic water are connected in parallel. When a fire occurs, a large amount of water is urgently needed for firefighting, and the domestic water supply is immediately cut off to ensure sufficient firefighting water; when the firefighting stops and the water pressure decreases, the valve automatically opens and is in a normally open state to restore the domestic water supply. The valve eliminates the need to set up a separate special fire-fighting separate water supply pipe network, which greatly saves construction costs and water consumption. The valve control has high sensitivity, safety and reliability, easy debugging and long service life.
