Description
Siemens Building Technology 656-0018 Normally Open Angle Valve
The Siemens Building Technology 656-0018 is a 3/4″ normally open (N/O) angle-body control valve engineered for dependable flow regulation in commercial and industrial HVAC hydronic systems. With a Cv flow coefficient of 4.6, this valve delivers accurate and consistent water or steam flow modulation, making it an ideal choice for heating and cooling coil applications, fan coil units, and building automation control loops.
Key Features
- 3/4″ pipe connection size for standard hydronic system compatibility
- Normally Open (N/O) operation — valve opens upon loss of actuator signal for fail-safe performance
- Angle body configuration for space-saving installation and reduced pressure drop
- Cv flow coefficient of 4.6 for precise flow capacity and system balancing
- Designed for use with compatible Siemens actuators in building automation systems
- Suitable for hot water, chilled water, and low-pressure steam applications
- Durable construction built to meet the demands of commercial HVAC environments
Application
The 656-0018 angle valve is well-suited for integration into building automation and energy management systems where reliable, normally open valve control is required. Its angle body design simplifies piping layouts in tight mechanical spaces, while the 4.6 Cv rating ensures proper flow sizing across a range of HVAC coil and terminal unit applications.
