This \u003cstrong\u003e2-way normally closed modulating valve\u003c\/strong\u003e features a 2-inch NPT connection and is engineered with a 40 Cv linear flow characteristic to ensure stable regulation in air handling units and heat exchangers. Designed for seamless integration, the \u003cstrong\u003eSiemens actuator\u003c\/strong\u003e accepts both 0-10 VDC and 4-20 mA control signals, operating on standard 24 VAC power. The bronze body construction paired with stainless steel trim provides the necessary ruggedness for closed-loop chilled water and heating applications. Equipped with a \u003cstrong\u003espring return modulating actuator\u003c\/strong\u003e, the assembly ensures a reliable fail-safe position during power loss, protecting critical equipment. Whether managing variable flow loads or maintaining tight temperature setpoints, this \u003cstrong\u003eSiemens valve and actuator\u003c\/strong\u003e combination delivers the technical performance required by professional mechanical contractors and building automation specialists.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLinear Flow Characteristic:\u003c\/strong\u003e Optimized 40 Cv rating provides ultra-stable modulation for precise temperature maintenance in hydronic loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Signal Compatibility:\u003c\/strong\u003e Supports standard 0-10 VDC or 4-20 mA inputs for easy integration with modern Building Automation Systems (BAS).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Build Quality:\u003c\/strong\u003e High-grade bronze valve body and stainless steel trim resist corrosion and handle high-pressure differentials.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFail-Safe Logic:\u003c\/strong\u003e Integrated spring return mechanism ensures the valve returns to a normally closed position upon loss of power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimplified Installation:\u003c\/strong\u003e 2-inch NPT threaded connections allow for standard piping integration without specialized welding or flange kits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the fail-safe orientation of this Siemens assembly?\u003c\/strong\u003e\u003cbr\u003e\nThis is a normally closed (NC) assembly.
