PTFE Lined Wafer Lug Type Pneumatic Control Butterfly Valve (D671F)Â Product features
1 pneumatic butterfly valve operating torque is small, the operation torque is one of the smallest of all valves, quick open and close, powered by compressed air, through the piston rack, mechanical drive rod gear, to a rotary output torque to rotate the valve plate 0~90 °, will be able to complete the opening and closing action quick, simple structure, volume small, light weight, small flow resistance, flow coefficient, good sealing performance. The scope of regulation. Is the execution unit automation control system of the instrument;
2 the electric - gas valve positioner, the electric signal and compressed air as a driving force, receive control input 0-10mA DC or 4-20mA DC current signal, the regulator will be compressed air, into the air pressure signal input and output, the rotation angle changes the valve plate (0-90 ° arbitrary angle), which regulates the flow rate better.
3 the electromagnetic reversing valve, valve position, with a AC220V or DC24V power supply voltage and the compressed air as the power, fast two bit on the fluid medium off control.
4 pneumatic actuator using the piston and crank conversion structure, large output torque, small volume, adopts fully sealed waterproof design high protection level. The cylinder body adopts the mirror cylinder, without oil lubrication, the friction coefficient is small, corrosion resistance, with superior durability and reliability. All transmission bearings with boundary self lubrication bearing lubrication without oil, ensure that the transmission shaft does not wear.

The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
Judge good or bad
1. Look at the hue and surface roughness of the edge banding strip. The color of the surface of a good edge banding strip is also very important. Whether the color is close to the customized product and is gorgeous. If the surface is very rough and there are pull marks, the quality is definitely not much better. This is the surface quality of the edge banding strip. It has nothing to do with the quality of the inner material of the edge banding, mainly the production process of the edge banding factory and the production technical skills of the employees. A good edge banding strip is: the surface must be smooth, no blistering or seldom bubbling, no drawing or few drawing, moderate gloss, not too shiny or too matte (unless there are special requirements).
2. Check the flatness of the surface and bottom of the edge banding and whether the thickness is uniform, otherwise it will cause the joint between the edge band and the board, the glue line is too eye-catching or the gap between the board and the edge band is too large, which will affect the overall beauty. Details determine success or failure, and often a small detail problem may bring an embarrassing situation where the overall effect is not good.
3. Whether the edge trimming is whitish, whether the surface of the bent edge strip is severely whitish, and whether the ground color of the trimming strip is close to the surface color of the board in question. PVC Edge Banding strips are mainly made of PVC and Calcium Carbonate plus additives. If the calcium carbonate content is too high, whitening of the edge banding and bending will occur, which proves that the quality of such products is not good.
4. Whether the strength is okay and whether there is elasticity. High strength means good wear resistance, and the corresponding quality is better. Too high strength also means increased processing difficulty. Low elasticity means low wear resistance and low aging resistance. In addition, according to actual production needs, manual trimming is generally required, and soft spots can be made appropriately, and the automatic edge banding machine can make hard points appropriately.
5. Whether the adhesive is applied evenly and whether it is easy to fall off during use.
6. Smell whether the PVC edge banding strips taste or not. Products produced with good quality raw materials generally have a small taste. If the taste is too large, it means that the quality of the raw materials used in production is relatively poor.
