Zhejiang factory direct 900X emergency shut-off valve

900X emergency shut-off valve Brand: Kim titanium valves Model: 900X Nominal Diameter: DN50 ~ DN600 Nominal pressure: 1.0 ~ 4.0Mpa Suitable medium: water, oil Suitable temperature: 0 ~ 80 ℃ Connection: Flange material: cast iron , cast steel, ductile iron, stainless steel 1. Introduction 900X emergency shut down valve emergency shut-off valve, is used for fire water with a life parallel to the water supply system in the direction of the valve used to allocate water, when the fire broke out, fire need a lot of water, 900X emergency shut-off valve immediately cut off the domestic water, enough to ensure that the main fire water, fire stops when the water pressure decreases, the valve automatically opens, showing a normally open state, domestic water supply restored. The valve of the system without having to fire a single separate dedicated water supply network, a significant reduction in construction costs and water consumption. Valve control of high sensitivity, safe, easy to debug, long service life. 2, emergency shut-off valve works when the main valve outlet pressure below the set pressure valve guide, the pilot valve in the open state at this time, the main valve chamber pressure and the main valve outlet pressure equal to the import and eating mouth existence pressure, water flowing through the outlet valve port, when the fire pump pump, or flattened pump pressure increases, more than lead valve set pressure, the main valve inlet guide valve tube control room pressure increases, the pressure increases in the spring, down pressed, drive spool down, so the pilot valve closed, then the main valve inlet pressure through the throttle supplement to the main valve cover chamber, due to valve flap downward pressure is greater than the upward thrust, the main valve closed is worth noting yes, the inlet pressure is less than the set pressure, the main valve is open, the inlet pressure is greater than the set pressure, the valve is closed. 3, emergency shut-off valve technical parameters Nominal pressure Mpa Mpa housing experiment seal test pressure Mpa Applicable media Suitable water temperature 1.0 1.5 1.1 0 ~ 80 ℃ 1.6 2.4 1.76 2.5 3.75 2.75 Zhejiang specializes in producing titanium valves hydraulic control valves, valves , the regulator valves, valve power, micro-resistance ease closure check valve, flow control valves, hydraulic automatic valves, intelligent automatic control valve, butterfly valve, mud valve, head-rotary valve and other products, widely used rise buildings, fire, water plants, power plants, metallurgical, petrochemical, coal, energy, food, medicine and other water distribution piping system.
