The 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.

Features and Benefits

• 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
