Quick Summary
The HTW-18C5 motorized valve combines a ball valve body with a 25Nm electric actuator for hydronic HVAC systems. It is used in chilled water and hot water loops for FCU, AHU, and zone control. This motorized valve works with on/off control, providing reliable shut-off or flow switching in building automation projects.
This page explains how the motorized valve is structured and how the actuator matches system wiring and loads. It helps confirm size selection, control logic, and installation conditions. It also supports common project questions and OEM needs, helping ensure correct selection and smooth integration.
Key Functional Highlights
(This section introduces the main control functions of the motorized valve and actuator assembly, and their engineering value in the relevant HVAC water system.)
(01) Protection Grade IP54
The IP54 protection level allows the motorized valve to work in typical mechanical rooms with dust and light moisture. This helps reduce the risk of actuator damage during operation. For projects with exposed installation, it improves reliability and lowers maintenance frequency over time.
(02) Dual Power Supply Options
This motorized valve supports both 220V and 24V power supply options. It allows easier matching with different control systems and site conditions. This flexibility helps reduce additional components and simplifies installation and commissioning work.
(03) On/Off Control for Stable Operation
The motorized valve uses simple on/off control logic for flow switching. This ensures clear control signals and reduces system complexity. It is suitable for zoning systems where stable shut-off and reliable operation are more important than modulation. For the modulating version, you can refer to this link: HTW-18C5-modulating. If you need modulating version, you can refer to this link: HTW-18C5 Modulating.
(04) Wide Size and Configuration Range
The motorized valve is available in 2-way and 3-way configurations from 1/2 inch to 2 inch. This allows proper selection based on pipe size and system layout. Correct sizing helps maintain flow balance and prevents pressure instability.
(05) BSP Thread for Easy Installation
Standard BSP thread ensures compatibility with most HVAC piping systems. It avoids the need for adapters in many cases. This helps reduce installation errors and ensures secure connection in different project environments.

Wiring and Flow Direction
(This section provides the wiring information for the actuator and the flow direction reference for the motorized valve in the relevant HVAC water system.)
Project Fit & Customization
(This section describes project suitability, system limitations, actuator-valve matching conditions, and available OEM options.)
This motorized valve is not suitable for steam systems or corrosive liquids. It should not be used beyond rated pressure or temperature limits. Unsupported control wiring or unmatched actuator conditions may affect normal operation.
Despite the limitations mentioned above, certain details—such as power supply, actuator type, connection type, or wire length—can be evaluated based on project needs and order quantity.
OEM supported, including logo printing, label customisation, packaging adjustment, and basic appearance identification. These details can be discussed based on order quantity and project requirements.
Certificates and Compliance
(This valve product is designed for HVAC applications and can comply with CE-related requirements for the European market.)

Frequently Asked Questions
Q1. How do I match the actuator with the valve?
You need to confirm the voltage, wiring type, and required control logic. The actuator and valve must match each other correctly. This helps avoid unstable switching or installation problems.
Q2. What control signal does this model use?
This model uses on/off control. It is suitable for simple open and close operation. It is not intended for modulating control applications.
Q3. How do I choose between 2-way and 3-way versions?
A 2-way version is usually used for shut-off control. A 3-way version is usually used for mixing or diverting. The correct choice depends on the piping design.
Q4. What media and pressure conditions should be checked?
This model is suitable for hot and cold water or neutral liquids. The system pressure and medium temperature must stay within the rated range. Please confirm these conditions before selection.
Q5. What is the MOQ and do you support samples?
We support samples for testing and evaluation. The typical MOQ is 100 units. Please feel free to share your project quantity with us.
Q6. How do we place an order and arrange shipment?
We first confirm your requirements and then provide a PI. Payment can be made by TT, PayPal, Visa, and similar methods. Terms such as EXW, FOB, and DAP can be discussed.
Q7. How long does product preparation usually take?
Non-customised samples are usually sent within 7 days. For customised orders, we evaluate quantity, labels, packaging, and matching details. Around 3 to 5 weeks is common, and 100 units usually need about one month.
Q8. How can the products be shipped?
Courier delivery such as FedEx, DHL, or UPS usually takes about 7 days to door. Air shipment is also about 7 days. Sea shipment usually takes one month or longer, depending on the destination.
