Spray valves precisely dispense various types of liquids and gases in the form of a flat or round spray.

Spray valves can dispense low viscosity liquids (with viscosity in the range of 0-25000 cps) such as water, milk and honey; medium viscosity liquids (with viscosity in the range of 25000-100000 cps) such as mustard oil, dyes and paints; and high viscosity liquids (with viscosity of over 100000 cps) such as lubricant oils and greases.

You can use spray valves in various applications such as lubricators, paint spray guns or embossing equipment. Depending on your application needs, you can buy a water truck spray valve, an agricultural spray valve or an industrial spray valve. Each of these spray valves has different properties and abilities to handle a variety of fluids.

Some important parameters you must consider before buying spray valves are:

1. Type of fluid flowing through the spray valve
2. Operating pressure range
3. Type of material feed: continuous or batch wise
4. Required spray type: round or flat
5. Expected life of a spray valve

Action Steps
The best contacts and resources to help you get it done

Buy simple spray valves from reputable spray valve manufacturers

Once you identify your requirements, evaluate standard industrial spray valves available from reputable manufacturers to buy cost-effective devices such as rinse spray valves and low flow-pre rinse spray valves.

I recommend: I&J Fisnar, a reputable spray valve manufacturer, offers stainless steel spray valves for the conformal coating that protects electric circuit boards. Kansas City Deaerator Company supplies all types and sizes of spray valves for the utility and industrial sector. Jensen Global is another supplier of spray valves for the electronic, medical and aerospace industries. Salvarani North America, another valve manufacturer, specializes in agricultural sprayer valves providing spray guns and spray wands for agricultural applications

Buy automated spray valves

If you want to better control the dosing volume and spray density, opt for automated spray valves.

I recommend: Henkel is a reputable manufacture of both simple as well as automated spray valves. You can also buy automated spray valves from Texas Industrial Remcor, another reputable manufacturer of spray valves and accessories.

Buy specialty or customized spray valves

If standard spray valves available in the market do not meet your requirements, opt for customized spray valves.

I recommend: EFD, a Nordson company, manufactures customized spray valves with high precision. You can buy a customized water spray valve at Ecodyne, another custom manufacturer of stainless steel spray valves.
