Three-piece Soft Sealing Ball Valve
Blowout-proof Stem and Primary Stem Seal
Stem shoulder is integral part of stem, retained internally to prevent stem blowout from pressure in body cavity. Primary stem seal prevents leakage to atmosphere, also serves as low-torque bearing.Precise, Smooth Ball
Ball sphericity and surface finish are key factors in valve life, pressure-holding capability, and operating torque. -
Floating Hard Seal Ball Valve
Rigid Split Body
Designed with extra bolts to assure positive alignment and maximum protection against bending stresses in the piping and forces produced by thermal distortion; seal is fire-safe metal-to-metal. -
Floating Soft Seal Ball Valve
Blowout-proof Stem and Primary Stem Seal
Stem shoulder is integral part of stem, retained internally to prevent stem blowout from pressure in body cavity. Primary stem seal prevents leakage to atmosphere, also serves as low-torque bearing.Fugitive Emissions Control
