  • Product Info
  • Literature

Overview

VGF Flanged Globe Valves are used for 2-position or modulating control and can be operated by ML6984/7984, ML6420/6425, ML6421/7421 Actuators, MP953 Pneumatic Actuators, Modutrol™ Motors with Q5001 valve linkage, or MN/MS Direct Coupled Actuators.

Features

  • ANSI Class 125 and Class 250 cast iron bodies with flanged end connections.
  • Face-to-face flange dimensions per ANSI/ISA S75.03 standard.
  • Sizes from 2-1/2 to 6 inches.
  • Stainless steel trim standard for long life span.
  • Self-adjusting packing.
  • Accurate positioning with equal percentage and linear flow characteristics to ensure precise temperature control.
  • Universal bonnet for direct-coupled electric and pneumatic actuators for easy mounting, or linkage coupled Modutrol™ Motors and MN/MS Series direct coupled actuators.
  • Constant total flow throughout full plug travel (3-way diverting models).
  • Not suitable for combustible gasses.
