When it all started was during World War II, when the first aerosol package arose to atomize droplets of liquid filled insecticide to protect servicemen from malaria. A few years later, Robert Aplanap, founder of the Precision Valve invented and mass produced aerosol valves and dedicated his career to being a world leader in smart, innovative, and efficient valve technology.Many people may refer to the Sprayer as the "baby sprayer" because it looks a little like an original baby bottle when baby bottles were made with Glass. "Preval" however is named after Robert Aplanaps company, Precision Valve. Preval Sprayer is sold in more than 50,000 retail stores worldwide, and can be purchased in almost every hardware, automotive and paint store in America. In June of 2009 Preval Division was acquired by Chicago Aerosol and in 2017 Chicago Aerosol was sold and We created Nakoma Products, LLC (www.nakoma.com) which proudly manufactures Preval Sprayer and other Preval Products.
