Contact SupplierStainless steel AISI-316 balls are used in spray pumps as a one way valve. SS-316 (Chromium 16-18%, Nickel 10-12%) has good corrosion resistance which is essential for personal care products and cosmetics. At times, in detergent pumps, AISI-304 stainless steel ball is used.
Tolerance of the steel ball ranges from G-100 to G-500 depending upon the quality and performance specifications of the overall product.
2, 3, 4 and 5 mm or 3/32", 1/8", 5/32" and 3/16 inch diameter balls are generally used.
Micro spray pumps in which these stainless steel balls are used include deodorant spray pumps, eau-de-cologne spray pumps, viscous liquid spray pumps (for liquid soap and detergents), gel pumps, toothpaste pumps, pocket spray pumps, spray pumps for metal container (without gas pressure) and insecticide spray pumps.
