Pneumatic operated Integral One Piece Flanged Plastic Ball Valve For Chemical Industry
FREE-VALVE Pneumatic Plastic One Piece Integral Flange Ball Valve are suitable for Seawater, water treatment, water features, fountains, aquariums, landfills, power plants, mining, transportation, chemical processing.
FREE-VALVE Pneumatic Plastic One Piece Integral Flange Ball Valves are straight type integral body design and made from the highest-quality plastic resins ,and they are corrosion resistant plastic flange end design quarter within turn valves with low pressure drops and reliable sealing.The ball itself is held in place by PTFE seats,which provide permanent lubrication and keep the valve bubble-tight.
Features
- Quarter turn handle operated ball valve,integral body design for Zero external leakage & Low fluid resistance.
- PTFE seat with elastomeric backing cushions ensure bubble tight shut-off and low fixed torque, while compensating for wear.
- Double O-ring seals on the stem for added protection.
- The full bore design,no extra friction losses.
- Chemical and corrosion resistant,suitable for contaminated water or corrosive media.
- Easy remote operation and intelligent control.
