VALTEK
Linear Globe/Anger Control Valves – Mark One
High performance: Positioning
• Accuracy to 0.1% full scale.
• The spring-cylinder actuated provides stiffness and maintains high positioning accuracy, repeatability, controlled high speed, and faithful response.
Heavy Duty Design
• Double top-stem guided and completely avoids contact between the plug and seat retainer.
• Many globe valve maintenance problems can be traced to cage-guiding. The close metal-to-metal contact between the cage and plug often results in galling and sticking.
• Plug with variable material and full contour design
Easy Maintenance
• Clamped-in seat ring: Valve may be disassembled quickly and easily by removing bonnet bolts
• Variable packing design for each media. Live-Load option.
