RVCX blind stem elastic seat seal gate valve

Rod elastic seat seal gate valve Overview:
For a long time, the general Z45X series of dark rod elastic seat seal gate valves used in the market generally exist water leakage and easy rust phenomenon. The Z45X-10 dark rod elastic seat seal gate valve produced by the company with the introduction of foreign advanced technology has overcome the general Z45X elastic seat seal gate valve poor seal, elastic fatigue, easy rust and other defects. The bottom of Z45X elastic seat seal gate valve adopts the same flat design as the water pipe, which is not easy to cause debris deposition, so that the fluid is unimpeded.
Z45X-10 dark rod elastic seat seal gate valve uses elastic gate plate to produce micro deformation of the taste effect, to achieve a good sealing effect, the valve has a light switch, reliable seal elastic memory and long service life and other significant advantages. It can be widely used in tap water, sewage, construction, food, power, medicine, metallurgy, textile, energy and other fluid pipelines as regulating and intercepting devices.
Z45X series can be selected according to different working conditions gray cast iron, ductile cast iron, cast steel three kinds of body material.
Z45X-10 dark rod elastic seat seal gate valve structure characteristics:
1, the whole valve cover dark rod design, compact structure; Valve stem nut and gate two-body structure, no blocking phenomenon occurs; Through the channel, no leakage cavity; Valve stem seal with "O" sealing ring.
2, has excellent anti-corrosion performance, the shell inside, the outer surface spray epoxy resin, when necessary, the inner surface lined with enamel; Connecting bolts using hex bolts, the top rubber seal.
3, reliable hygiene epoxy resin in line with the health standard GB/T17219-1998, the ram as a whole covered with rubber in line with health inspection; Valve stem, valve stem nut and other parts are made of stainless steel or bronze and other materials that are not corroded by water. Suitable for drinking water, water supply and drainage, sewage treatment, natural gas and gas, industry and food and other industries.
