High-performance rotary valves are also called double offset or double eccentric rotary valves. Along with the ability to withstand liquids and gases, our high-performance swing gates are also manufactured with a fire-resistant design.

 The addition of stoppers to our valves increases their effectiveness in controlling fluid flow and preventing overrun. Each gate is also manufactured with a double-sided pressure of class 150-900 and adjustable oil seals to ensure zero external leaks.

 The throttle valve is suitable for operation in high temperature, high pressure, fire protection, overheating insulation and other pipes for use in enclosed or regulatory environments. Its main characteristics are as follows: Compact design, small size, light weight, flexible operation, easy to use; Sealing efficiency of three-dimensional eccentric elastic or multilayer rigid material The sealing design is reliable to achieve zero leakage; The valve does not have a flange, which gives great convenience and beauty to the thermal insulation of the pipeline; It has high temperature resistance, high pressure, corrosion resistance, wear resistance and other advantages. It has high temperature resistance, high pressure, corrosion resistance, wear resistance and other advantages.

 This product is safe and reliable, has a low flow resistance coefficient, high temperature resistance, suitable for aggressive environments, etc.

 As a regulating and shut-off equipment, it is widely used in the processes of steam, hot water, water, oil, gas, natural gas, chemicals, acids, alkalis and salts in the pipeline.

 Excellent bi-directional sealing performance and low torque, as well as high processing performance;

• Linear flow characteristic, good regulating ability.
• The flange connection is easy to install, vertical and horizontal installation is possible.
• Plenty of sealing materials for the user.
• The valve can be used as an outlet valve at the end of a pipe with adjustable capacity.
• The valve seat ring and the body are combined, which increases the service life of the valve.
• It has good anti-erosion properties, is suitable for harsh environmental conditions, and can be used to cut off and regulate the environment.

 The double eccentric, due to the formation of displacement in the single eccentric throttle valve, will be the basis of the center of rotation of the throttle plate (i.e., the center of the valve shaft) and the center line of the body, so that during the valve opening process, the sealing surface of the disc will be sealed faster than the single eccentric throttle valve. the sealing surface of the valve seat, the disc rotates 8 degrees to 12 degrees, the sealing surface of the rotary plate is completely separated from the sealing surface of the valve seat. Fully open, a larger Y gap is formed between the two sealing surfaces, according to the butterfly valve type, which significantly reduces extrusion deformation and mechanical damage between the two sealing surfaces, improving the sealing performance of the valve.

 The design characteristics of both the stem axis and the center of the butterfly plate also differed from the center of the body. The double eccentric effect causes the valve to turn, the oily plate can exit the valve seat quickly, which significantly eliminates unnecessary excessive compression of the disc and valve seat, scratches, reduces opening resistance, reduces wear and increases the service life of the valve seat, significantly reduces scraping and at the same time the metal seat of the throttle valve with The double eccentric can also be used to improve throttle operation in high temperature conditions. But because of its position, the sealing principle is to create a sealing structure, namely the oil plate and the sealing surface of the valve seat for internal contact, through the extrusion seat of the disc, caused by elastic deformation, creating a sealing effect, so the requirements for the closed position are very high (especially for the metal seat), the ability to withstand low pressure. This is why people think that a traditional butterfly valve cannot withstand high pressure and a large number of leaks.

 This butterfly valve is suitable for the production of food, beverages, pharmaceutical, chemical and other industrial pipelines, as well as for environmental protection, water supply and drainage processes as a lift or adjustment of the medium supply.

• Reasonable design, compact structure, quick opening and closing:
• Low opening torque, friction when the valve rotates, long service life;
• Various body materials and composite sandwich O-ring, suitable for different environments;
• The wedge design ensures uniform sealing of the contact.

 The throttle valve is mainly composed of a valve body, a rotating shaft, a valve plate, a seat and a drive mechanism (handle, worm and worm wheel, gas dynamic or electronic device), etc., driven by a drive shaft and the rotation of the throttle plate to achieve the purpose of opening and closing and regulating the flow.

• Simple and compact design, compact and light weight, easy to disassemble, transport and install.
• Quick on/off by 90°. Operating torque with little effort.
• Good tightness, long service life, the ability to achieve zero leakage.
• A wide range of materials suitable for different environments.
• Similar linear flow characteristics, good regulating ability.

 Valves used in pipeline systems that require double-sided sealing, frequent opening and closing, and high reliability requirements, especially in important fields such as food processing, beverage production, pharmaceuticals, chemical industry and other clean pipelines, as well as petrochemicals, electric power, metallurgy, transportation, large-scale construction and other fields. for opening and closing or regulating the media flow.

 The valve is equipped with a high-performance composite sealing material or a welded alloy steel seal, which ensures corrosion resistance, leak-free operation and long service life. The unique floating seat design, which provides a two-way valve seal, completely solves the problem of one-way eccentric throttle valve seal. This valve has all the advantages of a three-center throttle valve, as well as high tightness and reliable two-way movement.

 The valve has a universal connection with a plate and a tip of the second type; mechanical transmission, engine start and three operating modes at the user's choice. When choosing an electric throttle valve, the contract must specify all the necessary accessories, a pneumatic device with an electromagnetic check valve, gas components, a signal box, a manual mechanism locator and other accessories available for selection.
