XOMOX® FK Soft Seated Ball Valve

The new XOMOX® FK Ball Valve combines all critical safety and performance features required for demanding applications in the chemical process industry.

Features And Benefits

  • Three independent stem seals offer superior fugitive emissions control, certified to the following standards: EPA Method-21, ISO-15848, and TA-Luft according to VDI 2440.
  • Self-relieving seats permit relief of excess pressure to protect the integrity of the valve while maintaining bidirectional operation.
  • Patented SX ball-stem design provides high maximum stem torque capability and built-in side load resistance for extended valve life under severe conditions including thermal-cycling.
  • Dual material spiral wound body gasket, including a PTFE chemically inert inner seal and a secondary graphite outer seal, is supplied as standard.
