Forespar MF850 Marelon Ball Valves

The Forespar MF 850 series of Ball Valves are precision moulded with high strength glass-reinforced Marelon®.

Its non-corrosive proprietary formulation of polymer composite compounds uses resin and additives to produce a superior marine-grade product that will not deteriorate like traditional bronze marine plumbing parts.

Their great strength, lightweight, and complete freedom from corrosion and electrolysis make them the ideal valve for controlling inlet and outlet water requirements above and below the waterline.

Marelon®  Ball Valves use NPSM parallel thread forms that require thread compound or Teflon® tape to seal.

  • Meet and exceed all Marine U.L., ABYC and ISO standards
  • UV stabilized
  • Operating temperature range: -40° F to +176° (-40°C to +80°C)
NOTE: Industrial or household fittings typically use the NPT (National Pipe Tapered) tapered thread. The marine valves, thru-hulls, tailpipes and seacocks used in boats employ the NPSM (National Pipe Straight Mechanical) parallel thread form. Tapered industrial fittings are not intended to be joined with parallel marine fittings.
