There are two types of dispensing valves: pneumatic and electric

Pneumatic: The dispensing valve is connected up and down by the cylinder, valve body and material tank. The cylinder and valve body are separated by advanced sealing materials to prevent glue from invading the cylinder. The material cylinder and the air cylinder are connected to the main body of the dispensing valve to ensure concentricity with the air cylinder. Use the solenoid valve to move the pneumatic cylinder to drive the center rod to move up and down, and use the up and down movement of the center rod to achieve the opening and closing effect on the glue. According to the different ways of opening and closing, it can be divided into: plunger type dispensing valve, thimble type dispensing valve, lift type dispensing valve, spray dispensing valve, jet dispensing valve; different switching methods, applicable fluids are also The difference is that the back-suction dispensing valve adopts the structure of upward movement to close the glue, so that the glue is stopped and the glue is sucked back and cut off instantly, reducing the residual glue on the remaining needle, so that the dispensing does not cause leakage, stringing, etc. The body of the rubber valve is anodized by aluminum alloy, the sealing material is made of the latest PTFE material, and the parts in contact with the colloid are all corrosion-resistant materials.
Electric: Including pump body and driving part, with stator, easy to install. The stator and rotor structure design is adopted, and the sealing performance is good. The rotor and stator pairs form a self-sealing structure, which is easy to replace. Through the directional rotation of the rotor in the stator cavity, the medium conveying function is realized. The conveying process does not have any influence on the medium performance. At the same time, the reverse suction function of the medium can be easily realized through the reverse rotation of the motor to ensure the cleanliness of the medium and materials, no dripping, no pollution!
