Does the phrase “dispensing valve” mean something to you? Dispensing valves are common in industries handling chemicals and other substances. These valves are used to control the flow of fluid in and out of machines. This system is so efficient in controlling the distribution of liquid chemicals that various industries used this technology. The medical industry use it in transferring medical solutions to supplies such as syringes. The food service industry uses dispensing valves to put liquid products inside packaging products. The technology sector uses dispensing valves in the creation of various gadgets like cellular phones, laptops and the like. The cosmetics industry uses dispensing valves to place soaps, shampoos, facial washes and other beauty products inside packages that can be sold on markets. Likewise, the beverage industry packages drinks inside bottles and cans.
If you own a plant and plan to have your own system complete with dispensing valves, then you should know that there are different types of dispensing valves. Not every dispensing valve can be used to filter and package products. The main objective of filtering liquids is still there but each valve has its own usage. For you to know more about it, below are the different types of dispensing valves.
Spray valves work best with materials at low viscosity, normally less than 1,000 cps. If you plan to buy a spray valve, consider looking at the angle of the spray and the control module. This ensures that atomization is possible before the actual material flow and remains on after the flow stops. The process ensures that clogging is prevented.
Diaphragm valves are used to dispense low to medium viscosity fluids like glues, solvents and other corrosive agents. These dispensing valves are notable for being lightweight and easy to maintain.
Poppet valves have functions like suck-back and works with liquids that have low to mid high viscosity. This type of valve has a smaller shot size than a spooler valve, which is another type of valve.
Spooler valve works for high viscosity liquids like pastes and gels. Spooler valves operate at high pressure necessary to transport high viscosity fluids. These valves also have snuff-back or suck-back feature. Spooler valves have an automated control system. It can transfer fluid on a gasket.
Pinch-tube valves are for dispensing fluids that are based on solvent properties. These valves have disposable wetted parts and work with moderate precision and repeatability within the pinch-tube design. This is often used for meter and mixed applications and low-cost tubes are disposed at prescribed intervals.
These are just some of the types of dispensing valves that you can look into. Whatever the type, a dispensing valve can be used to transfer liquid or liquid-like substances from one container to another. So that is a good investment.
