Tru-Design Ball Valves from Raritan Engineering can be assembled to a thru-hull, eliminating the need for a bonding system. They are suitable for use on all hull types, aluminum, steel, wood or FRP. Designed for marine applications above and below the waterline, the Tru-Design Ball Valves are IMCI approved to ISO standard 9093-2 (put to the test for leakage when subjected to internal water pressure). The ball valves are offered with or without position monitoring. Position monitoring allows remote monitoring of the ball valve’s position making it easy to know if the valve is opened or closed. The body of the valve is made of a glass-reinforced nylon composite with high tensile strength resulting in a lightweight unit, free from corrosion and electrolysis issues. The valves are also UV resistant. Available in six sizes ranging from 3/4″ to 2″. MRSP $74.80 for the 3/4″; raritaneng.com
