Valve

HaiLin provides a complete range of valves designed for efficient fluid control in modern heating, ventilation, and air conditioning systems.

As essential components of Hcontrol systems, HaiLin control valves regulate water flow, temperature adjustment, and system balance to improve comfort, energy efficiency, and equipment performance.

The product portfolio includes thermal valves, balancing valves, electric modulating valves, fan coil motorized valves, and intelligent balance valves, supporting various applications in commercial buildings, office facilities, hotels, and smart building projects.

Reliable HVAC Control Valves for Heating and Cooling Systems

Efficient HVAC operation requires accurate control of chilled water and hot water flow within building systems.

HaiLin HVAC control valves are designed to work with:

Fan coil units (FCU)
Air conditioning systems
Heating systems
Chilled water systems
Building automation systems (BAS)

By providing precise flow regulation and automated adjustment, HaiLin valves help optimize HVAC performance and maintain stable indoor environments.

Thermal Valves for Automatic Temperature Regulation

HaiLin thermal valves provide reliable temperature-based control for heating and cooling applications.

These thermostatic valves automatically adjust water flow according to temperature changes, helping maintain comfortable indoor conditions while reducing unnecessary energy consumption.

Typical applications include:

Radiant heating systems
Fan coil systems
Room temperature control
Residential and commercial HVAC systems

Balance Valves for HVAC Water System Optimization

Proper hydraulic balance is essential for efficient HVAC operation. HaiLin balancing valves help regulate and distribute water flow throughout heating and cooling systems.

The HVAC balancing valves improve system performance by:

Maintaining consistent water flow
Reducing energy waste
Improving heating and cooling efficiency
Supporting system commissioning and adjustment

They are widely used in commercial HVAC projects, central air conditioning systems, and hydronic HVAC applications.

Electric Modulating Valves for Intelligent HVAC Control

HaiLin electric modulating valves provide accurate flow adjustment through electric actuator control.

Designed for automated HVAC applications, these modulating control valves support continuous adjustment instead of simple open/close operation, enabling more precise temperature management.

Key applications include:

AHU systems
Fan coil systems
Chilled water control
Building automation integration

These valves can work with HVAC controllers, DDC systems, and BMS platforms to achieve intelligent building management.

Fan Coil Motorized Valves for FCU Applications

HaiLin fan coil motorized valves are specially designed for fan coil unit (FCU) control in commercial and residential buildings.

These FCU motorized valves provide automatic water flow control for cooling and heating operation.

Features include:

2-way and 3-way valve options
Motorized actuator control
Fast response operation
Integration with thermostats and controllers

They are widely used in hotels, offices, apartments, and other HVAC terminal systems.

Intelligent Balance Valves for Smart HVAC Management

HaiLin intelligent balance valves combine flow regulation with advanced control functions to support modern building automation requirements.

Compared with traditional balancing solutions, smart balancing valves provide more efficient system management through intelligent adjustment and communication capabilities.

Applications include:

Smart building HVAC systems
Energy management systems
Large commercial HVAC projects
Central heating and cooling systems
