CTB Motorized Ball Valve with Manual Override
The CTB is a 2-way motorized ball valve with a manual override lever for reliable on-site operation during power or controller failure. Designed for demanding applications in building automation, industrial fluid control, HVAC, and municipal water supply. With DN15–DN100 sizes, 6N·m torque, and IP67 protection, it delivers precise flow control and long-term outdoor durability.
Key Selling Points
- Manual Override Lever – enables on-site open/close without pipe disassembly or water shutdown (source_fact: special_requirement).
- Dual Control Options – On/Off and Modulating (4-20mA) with ≤0.5s response time (source_fact: case_study).
- IP67 Rated – suitable for outdoor municipal pits and harsh environments (source_fact: params).
- Full Bore DN15-DN100 – minimizes pressure drop, ideal for water systems (source_fact: params).
- Modular Actuator – motor/circuit board independently replaceable, reducing repair costs by over 60% (source_fact: special_requirement).
- Certified Compliance – CE (EN 60335-1) and RoHS 2.0 (IEC 62321) (source_fact: certifications).

Models and Options
CTB series available in various sizes (DN15-DN100) with voltage options AC220V or DC24V. Control mode selectable between On/Off and Modulating. Optional WRAS/FDA certification for municipal water applications.
Materials and Structure
Body made of forged brass or stainless steel (SS304). Ball and stem are chrome-plated brass or SS304 for corrosion resistance. Actuator housing is engineered plastic with anti-rust coating. Modular design allows independent replacement of motor and circuit board.
Applications
Ideal for Building Automation Systems (BAS), industrial fluid control, HVAC systems, municipal water supply and drainage networks, sewage treatment, smart water management, fire protection, solar water heating, food processing, and pharmaceutical industries.
Customization
Custom voltage, wiring, and control signals available upon request. Special certifications (WRAS/FDA) can be added for potable water use. Material variations (brass or SS304) possible. OEM/ODM packaging and labeling supported.
Case Study
A large European municipal water group ordered 10,000 units in November 2024 for water supply networks and sewage treatment. The valves achieved precise 4-20mA regulation with ≤0.5s response time, zero leakage over 16 months, and a 40% reduction in maintenance costs. The order was delivered within 3 months, with full technical support provided.
