RVCX / Z45X-rising stem resilient seated gate valve utilizing plastic deformation of the overall compensation package to achieve a good sealing effect, to overcome the general bad valve seals, leaking and rusting phenomenon more effectively save installation space. Can be widely used for water , resilient seated as a regulator and shutoff device. I plant the introduction of the European high-tech valve manufacturing technology produced by the sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems and other fluid lines gate, gate utilization overall compensation package of plastic deformation to achieve a good sealing effect, to overcome the general valve seal bad, leaking and rusting phenomenon. It can be widely used for water, sewage, construction, petroleum, chemical, food, medicine, minor injuries, electric power, shipbuilding, metallurgy, energy systems and other fluid lines used as regulation and shut-off devices. Overall package of plastic: plastic gate with the overall package, its good coverage performance and precise geometry, to ensure reliable seal life. 2. Light weight: ductile iron valve body is made of light weight, easy installation. 3. Flat Seat: The bottom of the pipe the same style flat seat design, does not produce debris siltation, more reliable seal. 4. Resistance to corrosion: non-toxic epoxy resin coating shaped cavity to prevent corrosion and rust, is available not only to drink, but can be used for wastewater system. 5. The three "0" Seals: valve stem three 0-ring seal, friction resistance, switch lightweight, watertight. Technical parameters Pressure Level: 1.0MPa, 1.6MPa valve pressure: 1.5MPa, 2.4MPa seal test: 1.1MPa, 1.76MPa Operating Temperature: 0 ~ 80 ℃ Applicable medium: water, gas, etc. First, the main component material Name Material Body gray iron, ductile iron, cast ductile iron gate inside the outer cover EPDM or nitrile rubber hexagonal bolts carbonization process nitrile rubber valve cover gasket gray iron, ductile iron, stainless steel stem "O" ring Nitrile rubber thrust bearing bronze bolt stainless steel Gland ductile iron, cast steel dust cover nitrile rubber hand wheel (drive cap) cast iron main technical parameters Nominal pressure: 1.0 ~ 2.5MPa Operating Temperature: 0 ~ 80 ℃ Flange Standard: GB / T 17241.6 GB9113 Nominal by: Test standard water, oil, gas and other:: 50 ~ 600mm Medium GB13927 AP1598 three main external connection size DN 50 65 80 100 125 150 200 250 300 350 400 450 500 600 L 178 190 203 229 254 267 292 330 356 381 406 432 457 508 HA 313 332 372 424 497 562 680 837 948 1010 1220 1280 1480 1665 HC 355 375 415 476 540 600 720 875 990 1050 1245 1310 1560 1750
