This is the Waterline Series Two-Way, Spring-Return, Plated Brass Ball and Stem Ball Valve Assemblies without End Switches.

These Ball Valves are designed to regulate the flow of hot or chilled water and, for some models, low-pressure steam in response to the demand of a controller in HVAC systems. Available in sizes 1/2 through 2 in., this family of two-way forged brass valves is factory or field mounted Spring-Return Electric Actuators for on/off, floating, or proportional control.

  • Forged Brass Body — provides 580 psig static pressure rating.
  • Chrome-Plated Brass Ball and Stem Assembly Standard — handles both chilled water and hot water applications with a fluid temperature range of 23 to 203°F (-5 to 95°C).
  • Graphite-Reinforced Polytetrafluoroethylene (PTFE) Seats — include 15% graphite-reinforced ball seals, providing better wear resistance.
  • 500:1 Rangeability — provides accurate control under all load conditions.
  • Maintenance-Free Design — performs without failure in excess of 200,000 full stroke cycles in iron-oxide contaminated water.
