The company is now offering zinc-plated, corrosion-resistant refrigeration control valves as an option to its acrylic enamel valve coating. More desirable in specific applications, zinc plating comes standard for several solenoid valves including HS2, HS6, HS8A, and on all in-line HCK4 check valves. There is a small additional charge for the zinc plating option on some of the company’s 4-in. control valve product lines.
