Details RRHX next shot soft sealing gate: RRHX a clear shot soft sealing valve, RRHX next shot soft sealing valve Overview: For a long time the general gate valve used on the market, the general presence of leaks, rust phenomenon, Our introduction of foreign advanced technology Produced by the soft seal valve, the valve seal to overcome the general poor elasticity fatigue, rust and other defects. Soft sealing valve gate elastic deformation generates trace compensation to achieve a good seal, the valve has a switch, lightweight, reliable sealing elastic memory good and long life and other significant advantages. Usage: can be widely used in the fluid line is used as a regulating and shutoff device running water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy system and so on. Product Features: flat-style seat - often through traditional water pipe valve after foreign objects such as stones, wood, cement, paper, and other debris deposition in the bottom of the groove in the valve, is likely to cause can not be closed tightly The formation of water leakage, soft seal gate valve at the bottom of the pipe using the same flat design, easy to cause debris deposition, fluid unobstructed. Overall package of plastic - Valves with high quality rubber within the overall outsourcing glue, valves make vulcanized rubber vulcanization domestic first-class technology to ensure accurate geometry, and then solid rubber and ductile iron valves, not falling and elastic memory Good. Corrosion resistance - the body uses epoxy powder coating to prevent corrosion and rust body, and can be used sewage system. Easy to fragmentation of traditional cast iron gate hit often due to foreign objects, collision or overlapping fracture caused by other phenomena. As the body use iron, such a situation has to be drastically reduced. Three "O" ring seals - due to the stem with three "O" ring ring seal design can reduce friction switch, significantly reduce water leakage and water can not stop construction to replace the seals. Helps to drink - because of internal body to non-toxic epoxy resin coating, inner and outer surfaces of the gate are completely covered rubber and will not appear rust or corrosion of water available to drink. Casting body - the body using precision casting, precise geometry allows the body without any internal finish to ensure that the valve seal. Light weight - body with ductile cast made of lighter weight than traditional gate about 20% to 30%, easy installation and maintenance. Rising stem resilient seated gate valve, in addition to having the advantage of the next shot outside resilient seated gate valve and the valve opening can be more intuitive, open and close quickly and reliably, so often use fire and industrial systems typically installed in a higher position from the ground. Z44X / RRHX type next shot resilient seated gate valve opening can be displayed, open and close quickly and reliably, so often use fire and industrial systems from the ground is usually installed in a higher position than the intuitive. Second, the next shot resilient seated gate valve - the main components of the material: Name Material Body gray iron, ductile iron, cast ductile iron gate + EPDM or nitrile rubber mats mouth nitrile rubber, EPDM Nitrile rubber seals bracket gray iron, ductile iron, stainless steel bolts stainless steel stem gland ductile iron, cast copper alloy stem nut hand wheel (drive cap) malleable iron three, rising stem resilient seated gate valve - the 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 ~ 400mm Medium GB13927 AP1598 four, the next shot resilient seat valve closure - main external connection size DN 50 65 80 100 125 150 200 250 300 350 400 L 178 190 203 229 254 267 292 330 356 381 406 HA 322 332 350 420 581 581 736 882 1009 1300 1380 HC 374 398 429 524 721 736 942,103,111,171,655
