Marelon - Marine Grade Ball Valves
Non-Corrosive Non-Conductive Fire Resistant Impact Resistant Temp. Range -40 to +176 degrees F U.V. Resistant Marelon is a formulation of glass-reinforced Dupont Zytel . It is optimized for marine use above and below the waterline with maximum U.V. inhibitors, and it will not support combustion. Additional marine benefits of the material are its extreme range of operating temperature and it's resistance to abrupt changes in temperature. VALVE MAINTENANCE:
All our valves are non-corrosive, but like any moving part in a marine environment, they required regular inspection and lubrication. Do not fail to actuate the handle and lubricate the seals on a regular schedule (water pump grease or even mineral oil will lubricate seals). Bottom and top connections are NPS (straight) thread. The use of products with NPS (straight) pipe thread is recommended only for low pressure applications, and then only with a generous application of pipe sealant or PTFE thread tape.
Marelon ballvalves work well in boat plumbing applications. No need to bond- they don't conduct electricity. Not bothered by sal water. Remember, these ballvalves are not the same as seacocks. Only seacocks should be connected to thru hull fittings.
