Product Description
Product Description
Butterfly valve simple structure, small size, light weight, only by a few parts. And only need to rotate 90° can quickly open and close, simple operation, while the valve has good fluid control characteristics. Butterfly valve disc is installed in the pipe diameter direction. In the butterfly valve body cylindrical channel, disc disc around the axis of rotation, rotation Angle between 0°~90°, rotation to 90°, the valve is fully open state. When the flanged butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop produced by the valve is very small, so it has good flow control characteristics. Butterfly valve has two sealing types: spring seal and metal seal. Elastic seal valve, sealing ring can be mounted on the valve body or attached to the disc periphery
Butterfly valve is also called flap valve, is a simple structure of the regulating valve, can be used for low-pressure pipeline medium switch control butterfly valve refers to the closing parts (disc or butterfly plate) for the disc, revolving around the valve shaft to open and close a valve.
Valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media and other types of fluids. It mainly plays a cutting and throttling role in the pipeline. Butterfly valve opening and closing part is a disc disc, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulating.
Because polytetrafluoron (PTFE) has strong corrosion resistance, stable performance, not easy to aging, low friction coefficient, easy to form, size stability, and can be filled, add appropriate materials to improve its comprehensive performance, get better strength, lower friction coefficient of butterfly valve sealing material, overcome the limitations of synthetic rubber, Therefore, polytetrafluoroethylene as the representative of polymer polymer materials and their filling modified materials, has been widely used in butterfly valve, so that the performance of butterfly valve has been further improved, the manufacture of a wider range of temperature and pressure, reliable sealing performance, longer service life butterfly valve

Product Parameters
The main characteristics of flanged butterfly valve are:
1, small and light, easy disassembly and maintenance, and can be installed in any position.
2, simple structure, compact, small operating torque, 90° turn to open quickly.
3, the flow characteristics of straight line, good regulation performance.
4. The connection between butterfly plate and valve stem adopts no pin structure to overcome the possible internal leakage point.
5, butterfly plate outer circle using spherical shape, improve the sealing performance and prolong the service life of the valve, with pressure open and close more than 50,000 times still maintain zero leakage.
6, the sealing parts can be replaced, and the sealing is reliable to achieve two-way sealing.
7, butterfly plate can be spraying coating according to user requirements, such as nylon or ptfe.
8, the valve can be designed as flange connection and clamping connection.
9, the driving mode can choose manual, electric or pneumatic.
Flange butterfly valve is suitable for temperature ≤120ºC or ≤150ºC, nominal pressure ≤ 1.6mpa water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy system and textile industries, especially for two-way sealing and valve corrosion occasions, as flow regulation and closure medium. | |

Installation Instructions
1. The valve must be kept in a dry and ventilated room, and the valve plate should be opened 4-5 degrees.
2. Long-term storage should be checked regularly. Machined surfaces should be cleaned of surface dirt once every 6 months.
3. When installing, carefully check whether the use of the valve is consistent with the performance specifications.
4. Before installation, installation and debugging personnel should carefully read the operation manual, electric device manual, circuit diagram, etc., and be familiar with the installation and debugging procedures.
5. Pay attention to the following items during installation:
A. Check whether there are sundries in the valve channel and sealing surface, and clean them in time. The valve should be installed in time after unpacking, and do not loosen the fastening bolts of the valve at will.
B. When butterfly valve is installed, the butterfly plate should be in the closed position.
6. The connecting bolts between the butterfly valve and the pipeline should not be tightened individually at one time, but should be tightened alternately in the corresponding direction of the circumference to prevent the flange breakage or leakage caused by uneven tightening.
7 butterfly valve is generally one-way use, installation should be noted, the direction of the arrow on the valve body represents the pressure direction of the medium when the valve is closed.
8. Butterfly valve can be installed in any Angle of the pipeline, but should not be inverted, usually vertical or horizontal installation.
9. If you need to adjust the flow during use, adjust the opening position of the driving device for control.
10. When the electric butterfly valve leaves the factory, the opening and closing stroke of the control mechanism has been adjusted well. In order to prevent the direction of the power supply from being wrong, the butterfly valve should be manually switched to the half-open position for the first time, and then switch to check whether the direction of the indicating disk is consistent with the direction of the valve.
11. Seal test must be carried out after valve repair.
