Marelon MF 850 Ball Valves

forespar ball valve

Marelon™ is the perfect material for marine plumbing systems. It's non-corrosive proprietary formulation of polymer composite compounds use resins and additives to produce a superior marine-grade product that will not deteriorate like traditional bronze. For use above and below the waterline. UL Approved and ISO compliant. ABYC compliant.

MF 850 series of Ball Valves are precision molded in high strength Marelon®. Their great strength, light weight, and complete freedom from corrosion and electrolysis make them the ideal valve for controlling inlet and outlet water requirements above and below the waterline.

Forespar engineers opened and closed one of our ¾” (19.05mm) valves 11,000 times, then submerged it in water with an air line pressurized to 40 p.s.i. connected to it. The result was an absolutely leak free condition with no evidence of wear on internal seals.

All valves sold throughout the U.S.A. have N.P.T. type threads. If specified, B.S.P. are available on valves sold outside of America.
