Quick Summary
The HTW-DH series motorized ball valve combines a brass valve body with an electric actuator for hydronic HVAC systems. It is used in chilled water and hot water loops for FCU and AHU zone control. The motorized ball valve operates with on/off control, providing reliable shut-off or flow switching in 2-way and 3-way configurations.
This page explains how the motorized ball valve is structured and how the actuator is matched. It helps confirm key technical points, suitable sizes, and control logic. It also supports typical selection questions and OEM requirements, so we can align the valve with your project conditions.
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) Protection Grade IP65
The IP65 protection level allows the motorized ball valve to operate in humid or dusty plant rooms. This helps avoid actuator failure caused by water splashes or particles. For projects with ceiling installation or exposed piping, this improves long-term reliability and reduces maintenance frequency.
(02) Flexible Power Supply Options
The motorized ball valve supports 24V, 110V, and 220V power supplies. This flexibility helps match different regional standards and control panels. It also avoids additional transformers or rewiring, which simplifies installation and reduces project cost and commissioning time. If you need modulating valves, you can refer to this link: HTW-MV13.
(03) SPDT and SPST Actuator Choices
Different actuator contact types allow the motorized ball valve to fit various control logics. SPST is suitable for simple on/off control, while SPDT supports more complex switching. This helps ensure correct signal matching with thermostats or controllers, avoiding control mismatch issues.
(04) Multiple Size and Flow Options
The motorized ball valve is available in 2-way and 3-way designs from 1/2 inch to 1.5 inch. This allows proper selection based on pipe size and flow requirement. Correct sizing helps maintain stable flow, reduces pressure loss, and improves overall system balance.
(05) BSP Thread with NPT Option
Standard BSP connection ensures compatibility with most international HVAC systems. For projects in the US or specific regions, NPT can be customised. This avoids installation issues and ensures the motorized ball valve fits directly into the piping system without adapters.
(06) High Differential Pressure Shut-off
The motorized ball valve supports up to 1.0 MPa differential pressure for shut-off. This ensures reliable closing even in systems with high pump pressure. It helps prevent leakage and ensures proper zoning control, which is important for energy efficiency and system stability.

Wiring and Flow Direction
(This section provides the wiring information for the actuator and the flow direction reference for the motorized ball valve in HVAC water systems.)
Project Fit & Customization
(This section describes project suitability, system limitations, actuator matching conditions, and OEM options for this motorized ball valve.)
This motorized ball valve is not suitable for steam systems or aggressive fluids. It should not be used beyond rated pressure or temperature limits. Incorrect control signals or unmatched actuators may cause failure.
Despite these limits, details such as voltage, actuator type, or connection can be adjusted. Wire length and control interface can also be evaluated. These depend on project conditions and order quantity.
OEM is supported for logo printing, labels, and packaging. Appearance details can also be adjusted. For larger orders, we can discuss actuator logic or connection requirements.

Frequently Asked Questions
Q1. How do I match the actuator with the valve?
You need to confirm voltage, control type, and wiring logic. The actuator must match the valve torque and switching requirement. This ensures stable operation.
Q2. What control signal does this valve support?
This motorized ball valve uses on/off control. It is commonly used with thermostats or relay outputs. It is not suitable for modulating systems.
Q3. How do I choose between 2-way and 3-way valves?
2-way valves are used for shut-off control. 3-way valves are used for mixing or diverting flow. The choice depends on system design.
Q4. What media and pressure conditions are allowed?
It supports water and glycol mixtures below 60%. Pressure should not exceed 2.0 MPa. Always confirm system pressure before selection.
Q5. What is the MOQ and do you support samples?
We support sample orders for testing. The typical MOQ is 100 units. Smaller trial quantities can be discussed based on project needs.
Q6. How do we place an order?
We confirm requirements first, then provide a PI. Payment can be made by TT, PayPal, or Visa. Terms like EXW, FOB, or DAP are available.
Q7. What is the lead time?
Standard samples are ready within 7 days. Custom orders need evaluation based on details. Typical production takes about 3 to 5 weeks.
Q8. What shipping options are available?
Courier delivery takes about 7 days. Air freight is similar. Sea shipping usually takes one month or more depending on destination.
