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.

2-Way and 3-Way 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.

6-Way Ball Valves

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.

PICVs (pressure-independent combi valves) prevent oversupply and reciprocal hydronic interference, reducing energy consumption and operational costs. Additionally, PICV enabled precise temperature control improves the comfort and wellbeing of building users. Siemens recommends PICVs especially for radiators, chilled ceilings, VAV and fan coil units.

Butterfly valves are the workhorse in a hydronic system needed to isolate flow with bubble-tight shutoff. At Siemens, we continuously challenge ourselves to improve butterfly valves to exceed hydronic system demands with improved performance, efficiency and value. So we set our sights on designing the best version of the most widely used butterfly valve type to be more robust and last even longer -- delivering better value. The valves are ideal for chilled water, hot water and open-loop cooling tower applications.

Available in 2- to 24-inch sizes (50 - 610 mm) with Cv ranging from 144 to 33,154. Siemens butterfly valves control hot and chilled water with up to 50% glycol over a temperature range of -40° F to 250° F. Used with A-Series industrial actuators and OpenAir™ damper actuators.
