XOMOX® Lined Ball Valves Series XLB

XOMOX® XLB Lined Ball Valves offer economical solutions for the vast majority of chemical applications while maintaining the highest possible degree of performance in terms of in-line leakage and fugitive emissions with the Patented SX stem seal design.

Features And Benefits

  • Lower torque smaller actuators, reduced costs, space and weight saving.
  • Compact design allows installation in space restricted areas in parallel piping systems.
  • Actuator mounting fully compliant with ISO 5211 allowing use of standardized mounting kits.
  • The SX seal in the XLB valve moves in conjunction with the spherical portion of the stem, maintaining a constant seal.
  • The body assembly has metal-to-metal connection that offers resistance against forces that may be created in the pipework.
