Description

The Valtek Mark One globe control valve offers superior performance in liquid and gaseous services, while also permitting easy, fast and inexpensive maintenance. The spring-cylinder actuated Mark One valve provides stiffness and maintains high positioning accuracy, repeatability, controlled high speed, and faithful response. The valve is designed so the spring, supply air pressure and fluid pressure combine to produce exceptionally tight shutoff. A self-aligning seat ring further enhances the shutoff capability. Industries the Mark One can assist are chemicals, water, oil & gas and power.

FEATURES & BENEFITS

  • Small, compact, lightweight body and actuator package
  • Stiff and high-thrust cylinder actuator offers position accuracy, repeatability, and assured response
  • Broad solutions envelope with significant flexibility

Advantages and Features:

Design lower total lifetime cost

• Factory Mutual approved as a fuel service valve (0.75–3 in/DN 20–80)

Compact and easy to install

• Cylinder actuator smaller than most competitor actuators

• Lower center of gravity than comparable actuators

• Lighter weight means less pipe stress from static and dynamic loads

• Separable end flanges allow the valve to be installed in many orientations and compensate for flange misalignment

Reliable, predictable service

• Stiff, high-thrust cylinder actuator

• Accurate positioning

• High repeatability

• Faithful response

• Controlled, high-speed stroking action
