•  Reinforced shaft (stem).
•  Dual o-rings on shaft.
•  PTFE thrust bearing on shaft.
•  PTFE seats, pre-energized with o-rings.

•  Full concentricity and mirror smoothness of ball assures easy, smooth, leakproof operation.
•  Dual sliding seats, each with triple o-rings.
•  All three ports are true union for cost, installation time, and space savings.
