Ball valves

Get the job done with ball valves

Siemens ball valves and valve actuators deliver comprehensive control solutions. Siemens has the highest close-off in the industry and the largest selection of valve trim finishes for chrome plated brass and 316 stainless steel. Siemens' premium grade materials and construction includes a better design blowout proof stem that withstands high pressure and a double O-ring stem packing. Every Siemens valve and actuator is factory tested and goes above and beyond with rigorous lifecycle testing for higher reliability. Create comfortable and efficient environments with the precise performance of Siemens ball valves.

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.

Better design

  • The blowout proof stem withstands high system pressure.
  • The 2-piece valve body design promotes fewer installation errors compared to 3-piece valve bodies.
  • The double O-ring stem packing prevents leaking and ensures long-lasting performance.
  • Wider material selection with trim finishes in  Chrome Plated Brass and Stainless Steel 316.

Highest close-off in the industry

Siemens ball valves provide exact control in all types of applications which provides savings and a smaller footprint.


Other valves on the market have a lower close-off which requires either a redesign or the need for a larger actuator, which increases cost and requires a larger footprint.  

Higher reliability

Every  Siemens valve and actuator is tested right from the factory line to assure longer performance. 


Siemens goes above and beyond with rigorous lifecycle testing of up to 60K full strokes and up to 1.5 million repositions for higher reliability.
