GB Flanged Butterfly Valve

If you care about specific parameters, let's talk straight: the diameter can range from DN50 to DN1200, which can basically cover pipes of all thicknesses; it can withstand pressures from PN1.0 to PN4.0MPa, meeting the pressure requirements of most industrial occasions; in terms of temperature, it can work normally in environments from -20℃ (low temperature) to 300℃ (high temperature). You can also choose the material-cast iron, cast steel, stainless steel, whatever suits you; the sealing surface is made of nitrile rubber or polytetrafluoroethylene, so you don't have to worry too much about leakage. The connection method is flange, which is fully in line with national standards such as GB/T 12238. It can be installed directly on-site without additional size modifications, saving a lot of construction time and costs.

Friends who have used butterfly valves may have encountered these troubles: difficult to open and close, poor sealing, and damage after a short period of use. Our national standard butterfly valve is designed to solve these problems specifically-it has an eccentric butterfly plate design, which reduces the force required for opening and closing by 30%, so it's easy to twist manually. If you choose the electric or pneumatic version, it can respond in 0.5 seconds with extremely high efficiency; the valve seat and butterfly plate fit very tightly, and the leakage is lower than the national standard requirement. Whether it's for clear water, oil products or gas, it can seal tightly; the inside of the valve body is also anti-corrosion treated, so even in acid-base environments, it can be used for many years, with a service life more than twice that of ordinary butterfly valves.

As for where it can be used, the range is even wider. It can be used in petrochemical plants to adjust medium flow, in municipal water supply to control water pressure, and in power plants to manage circulating water. Moreover, it works better when paired with floating ball valves. For example, in a sewage treatment plant, the butterfly valve controls the inlet flow, and the floating ball valve controls chemical dosing-with the two cooperating, the treatment efficiency is significantly improved; in a steel plant, the floating ball valve can withstand pressure in high-pressure scenarios, while the butterfly valve is responsible for stable adjustment. A complete set works like a charm, saving you a lot of hassle.
