Manual Ball Valves in PVC, CPVC, PVDF & Polypro




Design Advantages:

    1. Heavy-duty, extra-large diameter shaft is reinforced by additional resin and eliminates stem breaks.
    2. Double shaft O-rings.
    3. PTFE shaft bearing eliminates friction and wear.
    4. PTFE seats backed up with O-rings reduce the wear and tear of repeated cycling.
    5. Trunnion Design: Upper and lower supports retain ball under pressure. Trunnion design allows multi-directional flow; means that the valve is in no danger of being installed “backwards.”
    6. Concentric machined and mirror-polished ball.
    7. Dual sliding seats use triple O-rings for balance and maximum leak protection.
    8. Smooth flow path eliminates pressure loss.
    9. True union ends for ease of piping and removal.
