With the mature development of dispensing valve technology, many types of dispensing valves are now available. Types of Dispensing Valves They can meet the dispensing needs of different types and requirements. Therefore, when choosing a dispensing valve, customers can choose a suitable dispensing valve equipment according to their own adhesive or needs. However, there are so many types of dispensing valves on the market now, how can we summarize them?
According to the type, dispensing valves can be divided into two types: piezoelectric valves and pneumatic valves. A dispensing valve consists of three parts: a cylinder, a valve body, and a barrel. Piezoelectric valves use a stator-rotor structure design. Through the directional rotation of the rotor in the stator cavity, the medium conveying function is realized. It is a relatively common type of dispensing valve that is still constantly developing. Pneumatic valves are connected through gas, and the pressure of the gas pushes the plunger in the valve body to squeeze the medium, thereby achieving the dispensing effect. Pneumatic valves have been developed for a long time, so the technology is relatively mature, and now many manufacturers are willing to choose to use pneumatic dispensing valve equipment.
There are many types of dispensing valves, and dispensing valves can be classified according to many standards. Therefore, to find suitable dispensing valve equipment, you need to prepare your needs in advance. Classifying and selecting dispensing valve equipment according to your needs will have good results.

The stability of the piezoelectric valve dispensing process directly determines product quality. Common issues such as uneven dispensing, stringing, and glue leakage can be effectively addressed through parameter adjustments and optimized matching. Laike’s piezoelectric valves support multi-level parameter adjustments, enabling precise matching of pressure, injection frequency, and nozzle aperture according to the specific characteristics of different fluids.
Blocking the hole is Piezoelectric valve The most common failures in dispensing operations are often caused by fluid solidification, residual impurities, and nozzle wear, which directly affect dispensing accuracy and efficiency. Given the structural characteristics of piezoelectric valves, these issues can be addressed in three steps: “diagnosis—cleaning—inspection.” First, stop the machine and visually inspect the nozzle for obvious glue deposits or foreign objects, determining whether the blockage is temporary or a persistent issue caused by nozzle wear.
Piezoelectric valve: A highly efficient core component in the field of precision automation.
Piezoelectric valves leverage the inverse piezoelectric effect of piezoceramics to achieve precise control. With advantages such as low energy consumption, silent operation, and rapid response, they have become critical equipment in the field of precision manufacturing. Unlike traditional solenoid valves, which require continuous current to maintain their operating state, piezoelectric valves consume far less energy. Moreover, they operate without generating heat or producing magnetic interference, making them well-suited for high-demand operational environments.
