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.
