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
