The Mark One-X offers a cost-effective means of installing a small valve in a much larger line without line reducers or expanders. It is identical to a standard Mark One except for its body, which has expanded outlets.

  • Lower valve and installation costs made possible by using a smaller, lighter valve and eliminating line expanders and reducers (plus their associated welding and radiography requirements)

  • Reliable, predictable performance provided by the position accuracy, repeatability and assured response of the stiff and high-thrust, spring-cylinder actuator

  • Reduced downtime with clamped-in seat and self-aligning seat ring

  • Decreased inventory carrying costs from a high degree of interchangeability with Mark One Series valves
