Forespar Marelon Ball Valve 1" BSP Female Inlet & Outlet
Forespar® 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,
This makes them the ideal valve for controlling inlet and outlet water requirements
above and below the waterline.
Marelon engineers opened and closed one of our 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 in internal seals.
Maintenance is required and activating the seals using water pump grease will lubricate the seals
