200X vacuum regulator valve structural characteristics and uses 200X vacuum regulator valve from the main valve, pilot valves, needle valves, ball valves, micro filter and pressure gauge hydraulic control over the system. In use, when it is set outlet pressure, can automatically maintain a stable outlet pressure. This product is the use of self-control pilot valve, no other devices and energy, maintenance is simple, highly accurate pressure control by a small inlet pressure and flow impact, pressure regulator and reliable. This series of valves are widely used in high-rise buildings, living quarters and other water supply systems and urban water supply project. 200X pressure regulator valve works when the valve when the inlet water from the water flowing through the needle into the main valve control chamber, the outlet pressure to the pilot valve through the catheter effect. When the outlet pressure is higher than the pilot valve spring setting, the pilot valve is closed. Control room to stop the drain, then the main valve control chamber pressure rises and closes the main valve, the outlet pressure will not rise. When the valve outlet pressure drops the pilot valve spring set pressure, the pilot valve opens, the control room to the downstream drainage. Since the pilot valve system displacement is greater than the amount of water the needle valve, the main valve control chamber pressure drops. Open the main valve inlet pressure. At steady state, the control chamber inlet, the same as the drain, the same degree of opening of the main valve, the outlet pressure is stable. Regulating pilot valve spring can be set outlet pressure. 200X vacuum regulator valve main technical parameters Nominal pressure (Mpa) Shell test pressure (MPa) Sealing test pressure (MPa) maximum inlet pressure (MPa) adjustable outlet pressure (MPa) Applicable medium medium temperature (℃) 1.0 1.5 1.1 1.0 0.09-0.8 water 0-80 1.6 2.4 1.76 1.6 0.10-1.2 2.5 3.75 2.75 2.5 0.15-1.6 200X vacuum regulator valve main parts and materials Part Name Part Material Body WCB seat valve disc valve cover gasket O-copper alloy nitrile rubber ring 2Cr13 stem needle valve spring 50CrVA copper alloy copper alloy ball float valve copper alloy stainless steel 200X Micro filter vacuum regulator valve parts list: 1, 2 pilot valve, the main valve 3, 4 valve, pressure gauge 5 needle table 200X vacuum regulator valve connection size DN LA A1 H H1 FD mm D1 mm D2 mm n-Φd mm mm mm mm mm mm PN1.0 PN1.6 PN2.5 PN1.0 PN1.6 PN2.5 PN1 .0 PN1.6 PN2.5 PN1.0 PN1.6 PN2.5 20 180 292 136 342 247 116 105 105 105 75 75 75 58 58 56 4-13.5 4-13.5 4-14 25 180 292 136 342 247 116 115 115 115,858,585,686,865 4-13.5 4-13.5 4-14 32180292136342 247,116,140,140,140 100,100,100,787,876 4-17.5 4-17.5 4-1840240330 155,395,278,170,150 1,501,501,101,101,108,888 84 4-17.5 4-17.5 4-18 50 240,330,155,395,278 170,165,165,165,125 12512510210299 4-17.5 4-17.5 4-1865250350 165,405,298,180,185 185 185 145 145,145,122,122,118 4-17.5 4-17.5 8-18 80 285,365,175,430,313 210,200,200,200,160 160,160,133,133,132 8-17.5 8-17.5 8-18100360410 195,510,350,275,220 220 235 180 180,190,158,158,156 8-17.5 8-17.5 8-22 125 400,455,220,560,365 310,250,250,270,210 210,220,184,184,184 8-17.5 8-17.5 8-26150455475 230,585,420,355,285 285 300,240,240,250,212 2122118-228-22 8-26 200,585,530,255,675 450,460,340,340,360 295,295,310,268,268 2748-2212-22 12-26250650623 300,730,470,500,395 405,425,350,355,370 32032033012-22 12-26 12-30 300,800,700,340,760 490,580,445,460,485 400,410,430,370,370 38912-2212-26 16-30350860840 415,840,526,640,505 520,555,460,470,490 43043044816-22 16-26 16-33 400,960,880,430,910 570,715,565,580,620 515,525,550,482,482 50316-2616-30 16-364501075 9,304,601,030,610,780,615 640,670,565,585,600 53255054820-26 20-30 20-36 5001075980490 1,135,665,830,670,715,760 620,650,660,585,585 60920-2620-33 20-366001230 1060 5,301,270,725,920,780 840,845,725,770,770 68568572020-30 20-36 20-39 70016501130560 1,460,865,980,895,910,960 840,840,875,800,800 82024-3024-36 24-42 80017501230610 164,097,510,501,015 10251085950950 990 90590592824-33 24-3924-48
