Quick Summary
The HTW-MV13 modulating valve combines a valve body with an electric actuator for hydronic HVAC systems. It is used in chilled water and hot water loops for FCU, AHU, and zone control. This modulating valve supports continuous flow adjustment using 0–10V or 4–20mA signals, enabling accurate temperature control in BMS projects.
This page explains how the modulating valve is structured and how the actuator matches system signals. It helps confirm key points such as control logic, size selection, and installation fit. It also supports common selection questions and OEM options, helping align the valve with project needs.
Key Functional Highlights
(This section introduces the main control functions of the modulating valve and actuator assembly, and their engineering value in the relevant HVAC water system.)
(01) Protection Grade IP20
The IP20 protection level is suitable for indoor installation in control panels or plant rooms. This helps protect the modulating valve from basic contact risks. For clean mechanical rooms, it ensures stable operation and reduces unnecessary enclosure cost.
(02) 24Vac Power Supply Standardisation
The modulating valve uses a 24Vac power supply, which is common in HVAC control systems. This makes integration with controllers and BMS easier. It avoids mismatch with control transformers and simplifies wiring design in most commercial projects.
(03) True Modulating Control Capability
This modulating valve supports continuous adjustment based on control signals. It allows precise flow regulation instead of simple on/off switching. This improves temperature stability, reduces energy waste, and enhances comfort in variable load conditions.
(04) Flexible Size and Valve Structure Options
The modulating valve is available in 2-way and 3-way configurations from 1/2 inch to 1-1/4 inch. This helps match different piping layouts and flow requirements. Correct selection supports stable system balance and avoids over-sizing or under-sizing issues. If you need ball valve(on/off), you can refer to this link: HTW-DH.
(05) BSP Thread with System Compatibility
Standard BSP thread ensures easy installation in most HVAC piping systems. It reduces the need for additional fittings. This helps avoid leakage risks and simplifies on-site installation for the modulating valve.
(06) Multi-Signal Input for BMS Integration
The modulating valve accepts 0(2)–10Vdc and 0(4)–20mA signals. This allows flexible connection with different controllers. It ensures compatibility with most BMS systems and improves system control accuracy.

Project Fit & Customization
(This section describes project suitability, system limitations, actuator matching conditions, and available OEM options for this modulating valve.)
This modulating valve is not suitable for steam systems or aggressive fluids. It should not be used beyond rated pressure or temperature limits. Incorrect signal type or mismatched actuator may cause unstable control.
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, and packaging adjustment. Basic appearance identification can also be discussed based on order quantity.

Frequently Asked Questions
Q1. How do I select the correct actuator signal type?
You need to confirm if your controller outputs 0–10V or 4–20mA. The modulating valve must match this signal. This ensures stable and accurate control.
Q2. How do I choose the right valve size?
Valve size depends on pipe size and flow requirement. DN15 to DN32 are common for FCU systems. Proper sizing avoids flow instability.
Q3. Can this valve be used for mixing applications?
Yes, 3-way versions support mixing or diverting flow. It depends on system design. Please confirm piping layout before selection.
Q4. What media and pressure conditions are suitable?
This modulating valve supports water systems only. Pressure should be within 2.1 MPa. Always check actual system conditions.
Q5. What is the MOQ and do you support samples?
We support sample orders for testing. The typical MOQ is 100 units. Trial orders can be discussed based on project needs.
Q6. How do we place an order?
We confirm your requirements and provide a PI. Payment supports TT, PayPal, or Visa. Terms such as EXW, FOB, or DAP are available.
Q7. What is the lead time?
Standard samples are shipped within 7 days. Custom orders take about 3–5 weeks. Batch orders like 100 units usually take around one month.
Q8. How can the products be shipped?
Courier delivery takes about 7 days to door. Air freight is similar. Sea shipping usually takes over one month depending on location.
