This HVAC motorized ball valve ensures stable operation and reliable shut-off performance under standard HVAC conditions.
This page helps you quickly understand how this motorized ball valve fits your project. It explains valve structure, actuator matching, control logic, and key selection points, while also supporting OEM and project-based customization.
Key Functional Highlights
(This section introduces the main control functions of the motorized ball valve and actuator assembly, and their engineering value in HVAC water systems.)
(01) 220Vac Power Supply
This motorized ball valve supports standard 220Vac power supply, widely used in HVAC projects. It simplifies wiring and avoids extra transformers. This improves installation efficiency and ensures stable actuator operation.
(02) 2-Way and 3-Way Options
This motorized ball valve is available in 2-way and 3-way versions. 2-way is suitable for shut-off control, while 3-way supports mixing or diverting flow. This allows flexible system design for FCU, AHU, and zone control applications.
(03) Reversible Synchronous Motor
The actuator uses a reversible synchronous motor. This ensures stable opening and closing action. It helps improve control accuracy and reduces failure risk during repeated operation.
(04) Media Temperature Range
This motorized ball valve supports 2°C to 90°C media temperature. It is suitable for chilled and hot water systems. This makes it reliable across different HVAC applications.
(05) BSP Connection
The valve uses BSP thread connection. This ensures compatibility with common piping systems. It reduces installation errors and improves sealing reliability.

Project Fit & Customization
(This section describes project suitability, system limitations, actuator-valve matching conditions, and available OEM options for this motorized ball valve.)
This motorized ball valve is suitable for standard chilled water and hot water HVAC systems, including FCU, AHU, and zone control projects. It is not suitable for steam systems or corrosive media. It should not be used beyond PN20 pressure limits.
For standard HVAC water control, this valve is usually a practical choice when the project needs reliable shut-off, simple actuator control, and stable long-term operation. For steam, corrosive media, high-temperature industrial fluid, or unsupported control signals, another valve type should be selected.
Despite these limitations, power supply, actuator type, and connection standard can be adjusted. These can be evaluated based on project needs and order quantity. We are happy to support selection.
OEM is supported. Logo printing, label customisation, and packaging adjustments are available. Appearance identification can also be discussed based on order quantity.
Certificates and Compliance
(This valve product is designed for HVAC applications and can comply with CE-related requirements for the European market.)
Exhibition Moments
(Our team regularly participates in international HVAC exhibitions such as Febrava in Brazil, The Big 5 in Dubai, and ISK-SODEX in Turkey, etc.)
Frequently Asked Questions
Q1: When should I choose a motorized ball valve?
A motorized ball valve is suitable when the project needs reliable shut-off, low leakage risk, and simple on/off or 3-point water control in FCU, AHU, or zone HVAC systems.
Q2: What is the difference between 2-way and 3-way?
2-way valves control flow on/off. 3-way valves allow mixing or diverting flow. The selection depends on system design.
Q3: Can this valve support different voltages?
Yes, 220Vac is standard, and 24Vac or 110Vac options are available. Please confirm power supply before ordering.
Q4: What media can this valve handle?
This motorized ball valve is designed for chilled and hot water. It is not suitable for steam or aggressive fluids.
