FEATURES & BENEFITS
Increased uptime from the use of anti-thrust rings in the body-guided disc, which eliminates misalignment and galling.
Greater process control due to the integral hard-surfaced seat, which allows positive shutoff and seat life
Enhanced service integrity through an optimum flow shape that minimizes flow direction changes and pressure drops.
Lower operating costs are enabled by a die-formed, flexible graphite gasket seated to a prescribed bonnet torque that provides a reliable seal.
