Quick Summary
HTW-V61 is a motorized valve assembly that combines a valve body and actuator for hydronic HVAC water systems. It is used with chilled water or hot water circuits in zone control applications such as FCU, AHU, and BMS-linked projects. This model is designed for on/off control, helping manage water flow in a clear and stable way.
This page helps us confirm whether HTW-V61 is the right motorized valve for the project. It briefly explains the valve structure, actuator matching, size options, and key technical limits, while also helping with common selection questions. OEM support can also be discussed when the project needs a specific label, package, or basic identification change.
Key Functional Highlights
(This section explains the main control functions of the motorized valve assembly and how it supports stable water control in HVAC systems.)
(01) Normally Closed Design
A normally closed motorized valve helps the system return to a safe shut-off state when power is removed. This is useful in many hydronic HVAC projects where unwanted water flow must be avoided. It can also help reduce control confusion during shutdown, maintenance, or power interruption.
(02) Flexible Power Supply Options
This motorized valve platform can be matched with 24V, 110V, or 220V actuator options. That makes project integration easier when different control panels or site standards are involved. It can help reduce field changes and simplify actuator selection during project planning.
(03) SPDT or SPST Actuator Choice
Different actuator forms can suit different control habits and wiring preferences. This matters when the project already has a defined electrical logic or replacement standard. A correct match can make installation smoother and help later service work stay simple.
(04) 2-Way and 3-Way Size Options
HTW-V61 offers 2-way and 3-way versions from 1/2 inch to 1 inch. This gives more flexibility for shut-off or diverting duties in FCU and small AHU water circuits. It also helps engineers keep one product family across different pipe sizes in the same project.
(05) BSP Thread with NPT Customisation
The standard BSP thread suits many export and HVAC water system projects. When pipe standards differ, NPT customisation can be discussed for better installation matching. This helps avoid connection mistakes and reduces adjustment work on site.

Model Code (Sizes, etc)
(This section explains how the motorized valve model code relates to size, actuator type, and configuration selection.)
| Model Code | Size |
|---|---|
| HTW-V61-215/315 | 215 = 2 way + DN15 (1/2 inch); 315 = 3 way + DN15 (1/2 inch) |
| HTW-V61-220/320 | 220 = 2 way + DN20 (3/4 inch); 320 = 3 way + DN20 (3/4 inch) |
| HTW-V61-225/325 | 225 = 2 way + DN25 (1 inch); 325 = 3 way + DN25 (1 inch) |
| B | SPST Actuator |
| HTW-V61-220 refers to a 2-way DN20 (3/4 inch) valve with a standard 220Vac power supply, BSP thread, and SPDT actuator. To confirm the sub-model that suits you, please feel free to get in touch with us directly. | |

Wiring and Flow Direction

Project Fit & Customization
(This section describes project suitability, system limitations, actuator-valve matching conditions, and available OEM options.)
This model is not suitable for steam systems or media outside its temperature and pressure limits. It should not be used where the control signal does not match on/off logic. It is also not suitable when the actuator, thread standard, or pipe size is not correctly matched.
Despite the limitations mentioned above, certain details—such as power supply, connection type, or wire length—can be evaluated based on project needs and order quantity. We can also review actuator form and thread requirements before production. This helps reduce mismatch risk before ordering.
OEM supported. OEM logo printing, label customisation, packaging adjustment, and basic appearance identification can be discussed based on order quantity. For projects with clear quantity and target market needs, we can review the practical options together.
Certificates and Compliance
(This valve product is designed for HVAC applications and can comply with CE-related requirements for the European market.)

(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. How do we know whether this motorized valve suits our actuator requirement?
We first need to confirm the control type, power supply, and actuator form. If the project needs on/off control and the matching power standard is clear, selection becomes much easier. We also suggest confirming whether SPDT or SPST is preferred.
Q2. Can this model be used for both chilled water and hot water systems?
Yes, it is suitable for cool and hot water within the stated liquid temperature range. It is commonly used in hydronic HVAC systems where water flow needs clear open and close control. It should not be used for unsuitable media.
Q3. How do we choose between 2-way and 3-way versions?
A 2-way motorized valve is usually chosen for simple shut-off control. A 3-way version is more suitable when the water circuit needs diverting or mixing logic, depending on the project design. Pipe size should also be checked at the same time.
Q4. What should we confirm before selecting the thread and size?
We should confirm the pipe standard, connection size, and installation space first. BSP is standard for this model, while NPT can be discussed if needed. A correct thread and size match helps avoid site fitting problems.
Q5. Do you support samples and what is the MOQ?
Yes, we support samples for testing and checking. The usual MOQ is 100 pieces, but sample needs can be discussed first based on the project stage.
Q6. How do we place an order and arrange shipment?
We usually confirm the model details and project needs first, then provide a PI. Payment can be arranged by TT, PayPal, Visa, and similar methods. Trade terms such as EXW, FOB, and DAP can also be discussed.
Q7. How long does it take to prepare the goods?
Non-custom samples are usually sent within 7 days. If customisation is needed, we review quantity, labels, packaging, and matching details first, and this usually takes about 3 to 5 weeks. For a batch such as 100 pieces, preparation often needs around one month.
Q8. How are the products usually shipped?
Courier delivery is often the most practical option, such as FedEx, DHL, or UPS, and it usually takes about 7 days to door. Air shipment is also possible in around 7 days, while sea shipment normally takes over one month. The final method depends on quantity and destination.
