There are two types of Dispensing Valves: metering pumps and spray volumetric metering valves. A metreing pump allows a constant stream of fluid to be applied to a surface. A metering pump offers the highest level of control over the dispensing process. A controller is available for the metering pump that allows the user to adjust the flow of fluid and other process parameters. Measuring pumps, on the other hand, are designed for two-k fluid and manage the proportioning of resin. In addition, a controller is provided for monitoring the process parameters.
The Augur Valve is the most common type of valve used in automatic electronics assembly. This type of valve is used with materials with a medium to high viscosity. An electric motor drives an augur inside the dispensing chamber. When the valve is opened or closed, the material flows out through the valve. The speed of the motor, the diameter of the augur, and the viscosity of the material are all factors that determine the amount of material dispensed. The Augur Valve has a lower rate than piston valves, but is still able to dispense a dot of 0806 component in 50 to 80 milliseconds.
The DOPAG valve is ideal for low-to-medium viscosity media. They are precision-machined and require high reproducibility and accuracy. The DOPAG valve is available in a variety of series, designs, and sizes. A rotary valve is the best choice for a fast opening and closing time. A needle valve is an excellent choice if you need a high speed and precision. A positive displacement valve is suitable for the application of high-viscosity materials.
The DOPAG Dispensing Valves an excellent choice for a wide range of viscosity media. They are available in multiple sizes and can be customized for high and low-viscosity media. If you're looking for a more accurate valve, consider the Ellsworth Adhesives product line. This innovative company also supplies spools, mini-spools, diaphragms, and poppets.
The DOPAG valve is an excellent choice for low to medium-viscosity media. Its precision and reproducibility make it an ideal choice for this application. Different sizes and designs of DOPAG dispensing valves have specific benefits for the application. The size of the needle is an essential factor to consider when choosing a dispense valve. If the flow rate of the medium is low, a DOPAG valve may be the best choice.
When selecting a Dispensing Valve, it is essential to choose the right model for the specific application. A high-quality valve is able to dispense high-viscosity materials with high-speed accuracy. A Pinch tube valve is not designed for low-viscosity materials. In addition to a piston, an Augur Valve has a micrometric regulator and is a great choice for filled materials.
A Pinch tube valve is the best option for applications requiring low-viscosity materials. The pinch tube is made of a single piece and makes contact with liquid only once. Typically, the operating air pressure is 50Ps. These types of metering valves are used to spray materials with a low-to-moderate viscosity. It is also possible to spray small amounts of medium-viscosity materials at a low pressure.
The metering piston valve is another positive-displacement applicator. This type of Valve consists of a matching cylinder and piston. A pump fills the cylinder from the top while the material is compressed by the piston. The pressure is enough to keep the material flowing. These pumps are the best choice for dispensed liquids and gels. They are compatible with various adhesives and are the best choice for many applications.
A metering piston valve is another type of positive-displacement applicator. It consists of a cylinder and a piston. The metering piston pump compresses the adhesive into the cylinder and releases it from the top. A metering piston valve usually operates at a pressure of two to three psi. Its positive-displacement design allows the material to flow freely without clogging.
A metering valve uses a single volumetric piston and is powered by a DAV Tech smart controller. The metering valve is used in applications where a high-volume flow of fluid is needed. A metering valve can be either one-way or two-way. The latter type is used when the pressure in a fluid is too high to pass through a nozzle. If the dispensing pressure is too high, a refractory device must be installed over the valve.
