FORESPAR’S® MF 850

Forespa® 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.

Our 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 NPSM type threads. If specified, B.S.P. are available on valves sold outside of America.

The temperature range of Marelon® is -40° F to +176°        

(-40°c to +80°c).

Zero corrosion, zero electrolysis, light weight, strong marine grade

 

The temperature range of Marelon is: -40F to +176F or -40C to +80C

 

All Marelon products are carbon fiber reinforced

 

All 93 series valves are U.L. approved and ISO certified

MARELON “93” SERIES THREADED VALVES

These valves are designed to meet the needs of builders and owners who require the benefits of the Marelon® Integrated Plumbing System with “standard” female threads. These valves will work on Marelon®, bronze or stainless steel NPT threaded thru-hulls and are available with female/female (933332-8), straight tailpipe (933342-8) or 90o elbows (933352-8) already attached. All “93” series valves are full port (the I.D. of the ball is the same as the I.D of the barb).
