150LB-2500LB API Standard Forged Steel Flange Manual Gate Valve

Product Introduction：

It is suitable for small-diameter pipelines with a working temperature of -29～425℃ (carbon steel) or -29～500℃ (stainless steel). It is used to cut off or connect the medium in the pipeline. Different materials can be selected. Itis suitable for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.

Product advantage features

1. The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium. 2. It saves effort to open and close. 3. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure. 4. The shape is simple, the length of the structure is short, the manufacturing process is good, and the scope of application is wide.

Product Description DIN3352 F5 Iron Gland Type NRS Resilient Seat Gate Valve, DN50-DN600 cast iron gate valve Features 1. The ductile iron core is fully vulcanized with EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber. 2. Guides in the wedge and on the valve body ensure a uniform closure, safe operation ensured as the guides prevent overloading of the stem. 3. Stainless steel stem with rolled threads for high strength. 4. The valve can replace stem seals under pressure. 5. Full bore. 6. Body inside and outside fusion bonded epoxy coating with excellent corrosion resistant performance. cast iron gate valve Standard Design standard DIN3352 F5, EN1171 Flange drilling standard EN1092-2 PN10/PN16 Face to face standard EN558-1 Series 15 Hydraulic test standard EN1074-1 and 2 /EN12266 Seat:1.1*PN(in bar), Body:1.5*PN(in bar) cast iron gate valve Technical Parameters Nominal diameter(mm) 50～600 50～600 Nominal pressure(Mpa) 1.0 1.6 Testing pressure Shell(Mpa) 1.5 2.4 Seal(Mpa) 1.1 1.76 Suitable temperature -40°C～150°C Suitable medium Drinking water、sewage、seawater、irrigation,or other neutral liquid. cast iron gate valve Main Raw Material 1 Body Ductile Iron 9 Gland bolt Steel gr.8.8 2 Wedge Ductile Iron+EPDM 10 Handwheel Ductile Iron 3 Wedge Nut Brass 11 Gland Ductile Iron 4 Stem Stainless steel 12 O-ring EPDM rubber 5 Bonnet gasket EPDM rubber 13 Nut Stainless steel 6 Bonnet Ductile iron 14 Washer Steel 7 Thrust collar Brass 15 Bonnet bolt Steel gr.8.8 8 O-ring EPDM rubber Components may be substituted with equivalent or higher class materials. cast iron gate valve Dimension Size L D C B n-d b f H DN50 250 165 125 99 4-19 19 3 280 DN65 270 185 145 119 4-19 19 3 305 DN80 280 200 160 133 4-19 8-19 19 3 350 DN100 300 220 180 154 8-19 19 3 390 DN125 325 250 210 184 8-19 19 3 470 DN150 350 285 240 210 8-23 19 3 525 DN200 400 340 295 265 8-23 12-23 20 3 630 DN250 450 405 350 355 319 12-23 12-28 22 3 780 DN300 500 460 400 410 370 12-23 12-28 24.5 4 870 DN350 550 520 460 470 429 16-23 16-28 26.5 4 1100 DN400 600 565 580 515 525 480 16-28 16-32 28 4 1200 DN450 650 640 565 585 548 20-28 16-32 30 4 1300 DN500 700 670 715 620 650 582 20-28 20-32 31.5 5 1450 DN600 800 780 840 725 770 682 20-31 20-37 36 5 1650
