Ball valves

2-way Ball valve

Higher shutoff, low leakage, long-lasting performance.

Designed with an internal ball that has flow paths through it and rotates 90 degrees between PTFE seals to open and close to control flow. Most ball valves have a flow characterization disk which provides an equal percentage flow characteristic. Full port ball valves provide maximum flows and do not contain a characterization disc.

Siemens 2-way and 3-way ball valves are available in ½ to 2-inch sizes with Cv ranging from 0.4 to 160. These valves can control hot and chilled water with up to 50% glycol over a temperature range.

Siemens 6-way ball valves are available in ½ to 1-inch sizes with Cv ranging from 0.3 to 4.7. Used to control hot and chilled water with up to 50% glycol over a temperature range of 35° F to 250° F. These valves couple with the Siemens GDE161.1P OpenAir™ modulating damper actuator to provide single valve and actuator changeover and control of hot and chilled water.

  • 2-way and 3-way mixing or diverting
  • Stainless steel or chrome-plated brass ball
  • ANSI 250 pressure rating
  • Characterized flow optimizers provide equal percentage flow characteristic
  • 200 psi close-off with ANSI Class IV leakage (0.01%)
  • Uses on/off fail-safe, floating and modulating fail-safe and fail-in-place actuators
  • Chrome-plated brass ball
  • 232 psi pressure rating
  • High 58 psi close-off with 0% leakage
  • Female NPT union connections
  • Uses 0-10V modulating fail-in-place OpenAir™ GDE161.1P actuator for single valve and actuator changeover and control of hot and chilled water
  • Variety of ball sizes and flow coefficients (Cv) minimizes the need for downsizing pipes and accurately controls fluid through coils
  • Close-off leakage of 3-way bypass much lower at less than 0.1% compared to competitors that can be up to 2%
  • Double O-ring blow-out proof stem ensures long life and consistent performance
  • Reduces complexity in installation, commissioning and cabling, thus lowering costs.
  • Minimizes data points and costs since only a single actuator is required
  • 0% leakage prevents hot and chilled water from mixing
  • Built-in pressure compensation function prevents over-pressurization of coil as media temperature increases
  • Air handling units
  • Baseboard/radiant heat
  • Controlled isolation
  • Convectors
  • Fan coil units
  • Heat pumps
  • Unit ventilators
  • VAV reheat
  • Chilled/heated beams
  • Any four-pipe system utilizing the same coil to heat and cool
