What Are Power Plant Ball Valves?

These are quarter-turn shut-off valves specifically designed to control water or glycol-based fluids in:

  • Heating (boilers, radiators, hot water systems)
  • Ventilation (isolation of air handler water lines)
  • Air Conditioning (chillers, cooling towers, fan coil units)
  • Plumbing (domestic water lines, tank connections, bathroom fittings)

Applications in HVAC & Plumbing Systems

  1. AHU & FCU water inlet/outlet shut-off
  2. Pump isolation in chilled water and hot water loops
  3. Water softener and filtration piping
  4. Underfloor heating or cooling circuits
  5. Domestic plumbing – bathrooms, kitchen pipelines
  6. Rooftop water tank inlet/outlet valves
  7. BMS-controlled HVAC pipelines (automated options available)

Installation & Maintenance Tips

  • Use Teflon tape or pipe sealant for threaded valves
  • For flanged models, always torque bolts diagonally for even sealing
  • Insulate valves on chilled lines to avoid condensation
  • Use lockable handles for zone control and safety
  • Test for leaks before commissioning the system
  • Operate valves quarterly to prevent sticking or scaling
