Siemens butterfly valves are ideal for hydronic systems. We engineer them to isolate flow with bubble-tight shutoff, controlling hot and chilled water, including up to 50% glycol, from -40°F to 250°F.
Hydronic systems often struggle with inefficient flow isolation, energy waste and premature valve failure. Our butterfly valves solve these issues, delivering improved performance and efficiency. Achieve bubble-tight shutoff with zero leakage, eliminating wasted energy and extending product life.
Our valves provide bubble-tight shutoff with zero leakage, eliminating wasted energy and improving efficiency in your hydronic system.
Rely on valves designed for enhanced durability and extended service life. Benefit from robust construction and quality materials.
Take advantage of our free factory assembly and valve tagging service. We deliver pre-assembled and tagged valves directly to your jobsite, saving you valuable installation time and reducing overall expenses.
Achieve bubble-tight shutoff with zero leakage, preventing energy waste in your hydronic system. Our resilient seated valves are factory-tested for robust performance and meet ANSI 125 standards, ensuring reliable operation.
Utilize a high purity, peroxide-cured EPDM seat designed for continuous operation up to 250°F. This robust seat offers superior shape and memory retention throughout the valve's service life, ensuring consistent performance.
Rely on robust disc materials for demanding conditions. Valves 2-12 inches use 316 stainless steel. For 14-24 inch valves, electroless nickel plated ductile iron provides enhanced corrosion resistance.
