  • Increased uptime from pressure-balanced plug design that utilizes pressure to balance the forces acting on the plug and prevent taper locking
  • Lower maintenance costs via in-line maintainable design that allows sealant to be injected with the valve in any position and under pressure
  • Longer service life through seat protection against line media while the valve line is open
