How it Works Closed O-ring seal on smooth finish of stem provides leak-tight shutoff. Pressure on o-ring increases sealing effectiveness. Opening As stem is withdrawn, floating sleeve moves into position protecting the o-ring. Flow starts after 1½-turns of the handle. Throttling O-ring is protected by sleeve. Throttling is controlled across tapered section of the stem. Full Open Stem is withdrawn, permitting full flow with minimum pressure drop.
