ShenZhen Toupwell Technology Co.,Ltd

HVAC Valves and Actuators for Heating and Cooling Systems

Toupwell supplies HVAC valves and actuators for hydronic heating, central air conditioning and chilled-water or hot-water control projects. Our range includes electrothermal actuators, motorized ball valve products and electric butterfly valve assemblies.

As a valves and actuators supplier, we help HVAC distributors, equipment manufacturers and contractors match valve connections, actuator power and control signals. Specify whether you need an actuator only or a matched valve-and-actuator assembly so we can prepare the appropriate quotation.

Our Thermostats Wholesale range also supports coordinated sourcing of room controls and compatible water-flow control components.

Choose Your Valve and Actuator Type

Thermal Actuators for Manifolds and Zone Valves

Our electric actuator range includes TPA01 and TPA02 electrothermal products for compatible valves and heating manifolds.

Available configurations include normally closed and normally open operation, with voltage choices depending on the model. These actuators provide gradual opening or closing through an electrothermal mechanism rather than rapid motor-driven movement.

For replacement orders, confirm the valve connection, closing dimension, required stroke and operating force. Matching the thread alone does not establish full compatibility.

Motorized Ball Valve Control

Toupwell offers ball valve actuator configurations for switched, floating and proportional control applications. Selected TPBA products match TPBV-series valves for chilled-water and hot-water regulation.

Our modulating valve products include options for voltage or current input signals. Select the actuator according to the valve’s torque requirement, control interface and installation conditions.

Electric Butterfly Valves

Our electric butterfly valve range serves projects requiring powered quarter-turn valve operation.

The TPA range includes on/off configurations and multiple actuator sizes. Confirm valve diameter, flange standard, required torque, seat material and working conditions before selecting an assembly.

Representative Products and Selection Parameters

These are model-specific references, not interchangeable specifications. Torque ranges cover different actuator sizes; one actuator does not suit every valve diameter or operating pressure.

Match the Control Signal to Your System

Selected TPBA models offer proportional inputs and feedback options. State the required input and feedback separately when ordering.

An analogue actuator can work with a compatible controller without having its own Modbus or BACnet connection. Confirm the complete control arrangement before planning BMS integration.

Select for Flow, Pressure and Installation Conditions

Valve selection starts with the required flow and allowable pressure drop. Pipe diameter is one factor; valve flow capacity and close-off capability also affect performance.

Provide the following information for product matching:

● Application: underfloor heating, fan coil, AHU or another hydronic circuit.

● Medium and any glycol concentration or additives.

● Required flow, working pressure and differential pressure.

● Operating temperature and required shut-off performance.

● Nominal size, connection type and flange standard.

● Actuator voltage, control signal and feedback requirements.

● Required position following loss of power.

● Ambient conditions and enclosure protection requirements.

Valve-body pressure and temperature ratings are separate from actuator enclosure ratings. Confirm both parts of the assembly against the project conditions.

Coordinate Valves with Thermostats and Wiring Centres

For room-level heating, thermal actuators can be matched with compatible water underfloor heating thermostats and wiring centres.

For fan coil projects, FCU thermostats must provide the signal required by the selected valve actuator.

Check the controller’s output rating, total connected actuator load and wiring arrangement. A shared supply voltage does not automatically make two components compatible.

Supply and Customization Support from Toupwell

Toupwell combines thermostat expertise with related HVAC control products, helping procurement teams coordinate room controls, valves and actuators within one sourcing discussion.

Our team can review product configurations, assess replacement requirements and discuss branding or packaging needs.

Customization availability varies by product. Confirm the approved scope, minimum quantity, compliance documents and delivery schedule before placing an order.

Frequently Asked Questions

Q1: Can you supply actuators separately?

Specify whether your order requires an actuator, valve body or complete assembly. For actuator replacement, provide the existing valve model and mechanical interface details.

Q2: What is the difference between NC and NO thermal actuators?

Normally closed and normally open describe the intended valve state when the matched actuator is de-energized. Select the required action for the system’s operating strategy.

Q3: Will an M30 × 1.5 actuator fit every valve with that thread?

Not necessarily. Stroke, closing dimension and operating force must also match the valve.

Q4: Can a 0–10V actuator connect to an on/off thermostat?

It requires a compatible proportional signal or an approved control arrangement. Check both devices’ wiring and interfaces before connection.

Q5: Do all actuators return to a safe position when power fails?

No. Return behaviour depends on the actuator design. Specify any spring-return or other fail-safe requirement explicitly.

Q6: What information is needed for a replacement quotation?

Send photographs, model numbers, valve dimensions, medium, pressure, temperature, supply voltage and control signal. Include quantity and delivery destination.
