TruDesign Certified Ball Valves are designed and made in New Zealand for use in marine applications above and below the water line. The body of the Ball Valve is manufactured in glass-reinforced nylon composite with high impact and tensile strength resulting in a light weight unit, free from corrosion and electrolysis issues. The ball and sealing rings utilize a PTFE polymer to ensure a smooth action, and continuous ease of operation over many years. The Ball Valve is available in both BSP and NPS Parallel thread forms and can be locked in the closed position for use on toilet waste outlets.
