Pneumatic butterfly valve is a pipeline system and fluid engineering medium with one of the pneumatic valve, typically consist of valve and butterfly Industrial Valves pneumatic actuators, it has described as the unique place: 1, small and nimble convenient, easy disassembling and maintenance, and can be installed in arbitrary position. The butterfly valve butterfly plate installed on the diameter of the pipe direction. 5, the butterfly plate the surface of the cylindrical think appropriate and use the ball shape, increased for the use of valve sealing performance and prolong the survival of fixed number of year, with pressure opening and closing more than 50000 times remains zero leakage. Understand the unique place of pneumatic butterfly valve in the future, we will be able to better engage its unique place, foster strengths and circumvent weaknesses, and to cast it the use of the advantage, completes the protection office is also in order to better ensure use effect, and then extend it using the survival of the fixed number of year, make it better for our service. 7, the butterfly plate can be spray coating according to user requirements, such as nylon or ptfe. Tightly closed metal can be suitable for high temperature, the lack of flexibility tightly closed with the temperature limit is. 8, the valve can be preset into flange a petition and petition to the clamp. 6, tightly closed parts can change, and is tightly closed good achieve bidirectional tightly closed. Butterfly valves are tightly closed and metal tightly closed two tightly closed type. Butterfly valve not only in fuel, liquefied gas, chemical industry, water treatment and other common industry wide application, and also used in thermal power plant cooling water system. 3, compared with the nature of the pneumatic valve flow especially tending to straight line regulation performance is good. Because of the structural characteristics of symbol limit, uncomfortable should be resistant to high temperature, high pressure and corrosion resistance, abrasion resistance, etc. In butterfly valve technology has been known, its tightly closed way sees fit and use more tightly closed structure, tight sealing materials for rubber, ptfe, etc. 4, pneumatic actuators crank arm to the lag structure, used for manual device is applied, the fault when removing the air supply pipe directly using hand board manual operation can be successfully implemented. 4, pneumatic butterfly valve disc and stem the petition of right and use the structure without pin, overcome the possible leak point. Butterfly valve in the full paper and position, the butterfly plate thickness is only the resistance of the medium flows through the body, because this initiation by after the valve pressure drop is small, so the good traffic have a Marine valve stem special properties. Q: pneumatic butterfly valve's unique place and protection techniques answer: so far, butterfly valve, as a kind of used to successfully implement on-off and flow stem of pipeline system device, has been in the fuel, chemical industry, smelting metal, water and electricity to get very widely used in many fields. The structure principle of butterfly valve particularly adapt to the manufacture of large diameter valves. 。 3, pneumatic butterfly valve can be in level 180 & amp; 度; Lie within the scope of vertical installation, not the pneumatic actuator down inversion. Butterfly valve has simple structure, large and small, light weight, only by a small amount of several parts. Elastic tightly closed valves, tightly closed circle can be embedded in the body or attached to the butterfly plate peripheral. 2, simple, compact structure, small operation torque, 90 & amp; 度; Turn to open a sudden. And only need to rotate for 90 & amp; 度; Can rapid opening and closing, simple operation, at the same time the valve have satisfactory curb the special nature of the fluid. Pneumatic butterfly valve protection in the following aspects: 1, pneumatic butterfly valve before use should be clearly acknowledged, and valve under the premise of the whole paper pipe break through washing, lest any welding slags sundry scratch tightly closed surface. If asked butterfly valve as a traffic stem is applied, the main is accurately select the valve size and type. 5, such as found in the process of using gland leakage, tighten gland bolts can solve at once. Two common are set the by-pass pipe, pneumatic butterfly valve, when check repair or change the pneumatic butterfly valve, can be applied using the by-pass pipe process as usual. 9, drive form can be select manual, electric or pneumatic actuators. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation character of 0 & amp; 度; - 90 & 度; Between, rotate to 90 & amp; 度; When valves are brand the whole piece of paper. See fit and use metal than ordinary elastic tightly closed tightly closed valve valve live longer, but it's hard to do absolutely tightly closed. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
