Heavy Bodied PVC or CPVC Construction
Spears® True Union Ball Valves never rust, scale, or pit, providing exceptional chemical and corrosion resistance.
Buttress Threaded Double Union Nuts
Strong Buttress type threads on union nuts and seal carriers allow higher pressure handling capability and quick in-line installation and servicing.
Stops flow in either direction, allowing safe removal of the downstream union nut for system service or modification.
PTFE Ball Seats
Spears® PTFE floating seat design reduces seat wear for extended valve life, smooth operation, and bubble-tight shut-off. 100% factory tested.
EPDM or FKM O-ring Options
Choice of high grade, abrasion resistant EPDM or FKM elastomer O-rings allows application specific selection for optimum chemical resistance.
High Impact Polypropylene Handle
Features double stop engagement and exhibits excellent resistance to most chemical environments.
Developed to help prevent line fluids from leaking out in the event of ball valve stem damage. Engineered for high strength, the stem incorporates a special shear point to control accidental breakage. Over torquing breaks occur above the stem O-ring leaving the seal intact until repair or replacement can be made.
Full Schedule 80 Bore
In full open position, full bore virtually eliminates pressure drop, providing optimum flow.
Full 235 psi Pressure Rating
Maximum Internal Pressure at 73°F for the most demanding applications of 1/2″ – 2″ valves, 150 psi for 2-1/2″ – 6″ and all flanged valves.
