Double eccentric butterfly valve price

The Double Eccentric butterfly valve adopts an elastic pressure self sealing valve seat structure, which has bidirectional zero leakage and can achieve lower torque, reducing the procurement cost of the driving device. The cam effect sealing structure separates the valve seat and disc after the valve is opened at a certain angle, reducing friction and greatly improving the service life of the valve. It is widely used for cutting off and regulating fluids in various pipelines.

Product Features

Good sealing performance: Whether in soft or hard sealing form, the double eccentric butterfly valve can tightly fit the valve plate and valve seat when closed, effectively preventing medium leakage and achieving bidirectional full pressure difference VI level sealing, suitable for occasions with high sealing requirements.

Small opening torque: The double eccentric design separates the valve plate from the valve seat at the moment of opening, avoiding sliding friction between the sealing surfaces and greatly reducing the torque required for opening, making the operation more effortless.

Long service life: reduces unnecessary excessive compression and scratching between the butterfly plate and the valve seat, reduces the degree of wear, and extends the service life of the valve seat and butterfly plate, especially suitable for frequent switching conditions.

Low fluid resistance: When the butterfly plate rotates inside the valve body, the contact area with the medium is small, and the fluid experiences less resistance when passing through the valve, which can reduce energy consumption and improve the operating efficiency of the system.

Compact structure: The design is simple and clear, with a small volume, light weight, low installation space requirements, and easy installation, disassembly, and maintenance.

Application Area 

Metallurgical industry: can be used for preheating systems and dry dust removal systems in ironmaking blast furnaces, such as combustion air shut-off valves, combustion gas shut-off valves, etc.

Power industry: suitable for power circulation water systems, steam pipelines, etc., used to control the flow and cutoff of media.

Petrochemical industry: Used in industrial pipelines such as petroleum and chemical industries to transport various corrosive and non corrosive media, such as crude oil, refined oil, chemical raw materials, etc., for the purpose of cutting off or regulating the flow of media.

Water supply and drainage engineering: can be used for urban water supply and drainage pipelines, sewage treatment plants, etc., to achieve flow control and interception of water.

Other fields: It is also widely used in gas, liquid, semi fluid, and solid powder pipelines and containers in construction, textile, papermaking, energy and other fields as regulating and intercepting equipment.
