Smart Flow for Smart Buildings: Valve & Automation Solutions for HVAC and Building Systems
—— Energy Efficiency, Comfort, and Control in Every Environment

1.Introduction

In modern architecture and HVAC (Heating, Ventilation, and Air Conditioning) systems, precise fluid control is the key to achieving comfort, energy efficiency, and sustainability. From office towers to hospitals and data centers, valves play a vital role in regulating water flow, balancing pressure, and ensuring system stability.

Tianjin Dingliu Valve Industry Co., Ltd. provides comprehensive valve and automation solutions specifically designed for HVAC and building applications — delivering reliable performance, efficient control, and easy maintenance for both new installations and retrofitting projects.

2.Product Overview

Dingliu’s HVAC and building system valves cover the entire water and heating control chain:

Butterfly valves (wafer and flanged type): lightweight, compact, and ideal for chilled and hot water pipelines, available in PN10/16 and Class 150.

Balancing valves (manual and automatic): ensure precise system flow balance for optimized energy efficiency.

Control valves: used in heating, cooling, and ventilation loops for stable temperature and flow regulation.

Electric and pneumatic actuators: enable smart building automation with real-time feedback and remote operation.

Gate and check valves: reliable isolation and backflow prevention for HVAC and plumbing systems.

Strainers and filters: protect equipment by removing impurities and maintaining clean flow.

All Dingliu valves are designed for long service life, low torque, and minimal leakage, with options for EPDM, NBR, or PTFE seats suitable for various temperature and pressure ranges.

3.Case Study

In a commercial complex and hotel project in Southeast Asia, Dingliu supplied flanged butterfly valves, control valves, and balancing valves for the central air-conditioning and hot water systems.

Working conditions: chilled water 5–12°C, hot water 80°C, PN16 pressure.

Challenge: maintaining stable temperature control and reducing energy consumption in a large, multi-zone system.

Solution:

Installed DN50–DN400 control and balancing valves integrated with the building’s automation system.

Used electric actuators with Modbus communication for centralized control.

Result:

System energy efficiency improved by 22%.

Temperature deviation in each zone reduced to less than ±0.5°C.

Maintenance frequency dropped significantly due to durable sealing and smooth operation.

4.Solutions Provided

Dingliu’s valve and automation solutions address the specific needs of HVAC and building systems:

Energy-saving design: low-flow resistance and precision control improve overall system efficiency.

Smart automation: integration with BMS (Building Management Systems) via BACnet, Modbus, or DDC protocols.

Durable materials: ductile iron, stainless steel, and brass options ensure long life in both heating and cooling systems.
