What's new in Valves

A better butterfly valve

Siemens enhanced resilient seat butterfly valve series uses the best materials to withstand continuous high temperature operation at 250°F. The valve disc is built for high corrosion resistance and increased strength. While these valves are improved for continuous high-temperature use, every hydronic system can benefit from these butterfly valves for affordable long-lasting performance.

Rack and Pinion Spring Return Actuator for PICVs

Siemens manufacturers all sizes of spring return actuators for Pressure Independent Control Valves and serves as a single-source supplier for all types and sizes, from ½ inches to 6 inches. The pressure independent control series rack and pinion actuator couples an OpenAir™ GPC actuator to a 1 ½ or 2-inch pressure independent control series two-way valve using a linkage. The linkage transforms the actuator rotary movement into the linear motion required to position the valve.

Free factory assembly and valve tagging

Valves and valve actuators are assembled and tagged for direct delivery to any jobsite, free of charge. All you do is specify each valve’s location when placing your initial order and we will tag them before shipping to save you installation time and expense. For questions call 800-516-9964 or email bgcustomersupport.us.sbt@siemens.com

Quote that says, "If I want the leaving discharge air temperature to be 54.3 degrees Fahrenheit, I can get it to be 54.3 degrees Fahrenheit. And if I want 52.5 degrees Fahrenheit, I can get that. Before, I didn't have that kind of control." -Chief Engineer, Peachtree Center North and South Towers

Siemens pressure independent control valves reduce Peachtree Center’s energy usage by 13.8%

Commercial office buildings require a vast amount of energy and water to heat and cool the indoor environment. Peachtree Center was no exception, and the hot, humid Atlanta summers made the challenge even more daunting. Siemens presented Peachtree Center with an innovative and cost-effective solution using pressure independent control valves.
