New Style: High Flow Rotalock Valve Range

Heldon has developed a new range of High Flow Rotalock Valves, Salt spray testing was performed in conjunction with a standard nickel plated rotalock valve,commonly used within the refrigeration industry. This displays the distinct benefits of the Zinc Blue Passivated coating.
Standard Nickel plated Rotalock valve showed obvious signs of rust after 150 hours of salt spray testing. While the New Heldon High Flow Rotalock Valve with Zinc & Blue Passivate coating showed no obvious signs of rust, even after 300 hours of salt spray testing.
