Overview

Used for proportional control of hot or chilled water and glycol solutions (to 50 percent concentration) and for two-position control of low pressure steam in closed loop HVAC systems.

Features

  • Sizes range from 2-1/2 to 6 inches.
  • Stainless steel stem with serviceable Teflon packing.
  • Valves utilize direct mounting valve actuators, Q5020/Q5022 linkages with Direct Coupled Actuators, or Pneumatic Valve Actuators to operate the valve.
  • Equal Percentage flow characteristic.
