Repeatable Dispensing for Fluid Materials
The spool valve is a great valve for dispensing materials such as masks or other fluid encapsulants. A great benefit of the spool valve’s operation is the suck-back feature. When the valve is open, it opens by pushing the sealing rod down. This action allows material to flow around the rod. At the end of the dispense cycle, the rod retracts upward, creating the suck-back which helps to break material strings ...more (pdf)

Great option for fully automatic systems
Time Pressure is a simple method of dispensing materials that may damage more expensive valves. This dispense method works by applying pressure to the syringe. This pressure pulse is controlled by the software and can be used to dispense either lines, fills, or dots. The amount of pressure is automatically controlled through the software. The amount of pressure is determined by a relationship between the material being dispensed and the application flow rate. When dispensing is finished, an adjustable vacuum is applied to the syringe that prevents material from dripping. The vacuum is adjustable to avoid pulling air into the needle ...more (pdf)
