FORESPAR’S® MF 850 ball valve

Product Description

FORESPAR’S® MF 850

Forespar® MF 850 series of Ball Valves are precision molded in high strength glass-reinforced Marelon®. Great strength, light weight, easy installation and maintenance as well as freedom from corrosion and electrolysis creates the ideal valve for controlling inlet and outlet water flow above and below the waterline.

Stringent testing makes MF850 valves meet or exceed industry standards, allowing you to rely on our high quality. For instance, our engineers opened and closed a ¾” (19.05mm) valves 11,000 times, then submerged it connected to an air line pressurized to 40 p.s.i.. The result was an absolutely leak free valve with no evidence of wear on internal seals.

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

And, the operating temperature range of Marelon® is -40° F to +176°   (-40°c to +80°c), making the valves reliable in every climate and season.
