The Main Types of Dispensing Valves: Where Do They Work Best
Dispensing valves are designed to provide precise dispensing of industrial fluids depending on their applications. They provide reliability and accuracy in fluid control during fluid dispensing process. There are different types of dispensing valve systems. They can control tens of millions of trouble-free cycles before maintenance is required. Dispensing valves are ideal for bench top applications and automated dispensing systems. Check out these main dispensing valve systems and where they work best.
1.Diaphragm Valves: Diaphragm valve is designed for precise control of low to medium viscosity liquids. They are light-weight and easily maintained. They can perform high-cycle dispensing of many low-to-medium viscosity fluids such as solvents, cyanoacrylates, anaerobics, fluxes, and UV-cure adhesives. Diaphragm valves accurately place small dots and fine bead patterns.
2.Positive Displacement Valves: Positive displacement valves can drive high viscosity fluids and also meter them in very precise amounts. They are used in automated fluid dispensing system to deliver highly accurate micro deposits of fluids. Positive displacement valves can do dot dispensation, which is generally measured in mils. They can also be used to dispense glue and other cements for accurate filling applications.
3. Needle Valves: They are perfect for micro-shot deposits for industrial fluids. Needle valves can be adjusted when used for the high pressure and high viscosity materials. However, they are most suitable for applying beads of low-to-medium viscosity fluids.
4. Spray Valves: Spray valves are ideal for low-viscosity materials. They are used in spray coating systems. Spray valves ensure atomization takes place prior to material flow as it prevents clogging, which is common with industrial fluids.
Apart from above mentioned four valve systems, there are spooler valves, pinch-tube valves, and poppet valves. Dispensing valves are used for repeatable micro dispensing of a range of industrial liquids. Whether mounted on automated dispensing equipment or hand-held machine, dispensing valves are ideal for any dispensing solution. However, before purchasing valve system, do consider how the valve works, fluid characteristics, and how the material will be applied. This will simplify the dispensing valve selection process.
