Unique beveled edge ball design :
-
Minimizes pressure on seats to reduce cold flow and extend seat life
-
Prevents issues related to “breakaway torque” in valves that rest in the open position for extended periods
-
Provides positive tight shut-off at both high and low pressures.
-
Inherently prevents seat damage caused by the leading edge of the ball port cutting into the seat
-
Significantly reduces operating torque
Superior stem seal assembly:
-
Low operating torque reduces lateral loads on the stem seals for reliable performance
-
Blow-out proof stem with special attention given to surface finish.
-
Upper and lower seals provide balanced loading of stem seals
-
Standard Belleville spring washers provide constant “live load” on stem seals, assuring a tight seal under varying service parameters
In-line maintenance facilitates reduced downtime and lowers overall cost of ownership
