Quick Summary
The HTW-W27 fan coil unit motorized valve combines a forged brass valve body with an actuator for hydronic HVAC systems. It is designed for on/off control of chilled and hot water in FCU applications, supporting both 2-way shut-off and 3-way diverting control. This fan coil unit motorized valve helps maintain stable flow and reliable operation in daily use.
This page helps you understand how this fan coil unit motorized valve fits your project. It explains valve structure, actuator function, installation options, and common selection points, while also supporting OEM discussions based on project needs.
Key Functional Highlights
(This section introduces the main control functions of the fan coil unit motorized valve and actuator assembly, and their engineering value in HVAC water systems.)
(01) Spring Return Safety Design
This fan coil unit motorized valve uses a single direction motor with stainless steel spring return. When power is lost, the valve returns to its default position. This helps prevent uncontrolled water flow and improves system safety during power failure.
(02) 2-Way and 3-Way Options
The fan coil unit motorized valve is available in both 2-way and 3-way versions. 2-way is used for shut-off control, while 3-way supports diverting flow. This allows flexible use in different FCU system layouts.
(03) FCU Water Flow Control
This fan coil unit motorized valve controls the flow of chilled and hot water through the fan coil unit. It helps maintain stable room temperature and improves system response. Proper flow control also supports energy efficiency.
(04) Normally Closed Function
The 2-way version is normally closed, while the 3-way version supports diverting flow. This design helps ensure safe operation and predictable control logic. It is especially useful in building automation projects.
(05) BSP Connection with Custom Option
The valve uses standard BSP thread connection. For projects requiring NPT, customization is available. This helps match different piping standards across regions.
