Flow That Protects Cities: Advanced Valve & Automation Solutions for Water Treatment and Municipal Engineering

—— Reliability, Efficiency, and Sustainability in Every Drop

1.Introduction

Water is the lifeline of every city — and behind every stable water supply, sewage treatment plant, or municipal network, there is a reliable valve system ensuring continuous, safe, and efficient flow.

Tianjin Dingliu Valve Industry Co., Ltd. provides complete valve and automation solutions designed for the diverse needs of municipal and water treatment projects — from clean water distribution to wastewater recycling and flood control systems.

Built on years of manufacturing expertise and international certifications (CE, SIL, ISO9001, ISO14001), Dingliu’s products deliver reliability, safety, and environmental protection across global municipal infrastructures.

2.Product Overview

Dingliu offers a wide range of valves tailored for municipal and water treatment systems, including:

Resilient-seated gate valves: the backbone of water supply and distribution networks, offering tight sealing and long-term reliability.

Butterfly valves (centerline and double-eccentric): ideal for pipeline isolation and flow regulation in water plants, pumping stations, and pipelines up to DN2000.

Hydraulic control valves (200X, 300X series): ensuring automatic pressure, flow, and level regulation in water supply systems.

Check valves: preventing reverse flow and water hammer in pumping and booster systems.

Air release valves: improving system stability and reducing pressure surges.

Pneumatic and electric actuators: enabling automation and remote control for intelligent municipal networks.

All products are available with ductile iron, stainless steel, or epoxy-coated materials, ensuring durability in both clean and wastewater environments.

3.Case Study

In a municipal water distribution project in North Africa, Dingliu supplied double-eccentric butterfly valves and pressure-reducing control valves for a city water supply upgrade.

Working conditions: DN800–DN1200 pipelines, 1.6 MPa pressure, varying inlet conditions.

Challenge: unstable pressure fluctuations leading to frequent leakage and pipe stress.

Solution:

Installed 300X pressure-reducing valves with pilot control systems.

Integrated electric actuators with remote monitoring via SCADA.

Result:

Outlet pressure stability improved by 35%.

Water loss reduced by 22%.

Maintenance frequency dropped due to superior valve sealing and corrosion protection.

4.Solutions Provided

Dingliu’s valve and automation systems deliver precision, safety, and reliability for modern municipal infrastructure:

Automatic control: hydraulic and electric valves adjust flow and pressure dynamically.

Corrosion protection: fusion-bonded epoxy coatings resist rust and extend lifespan in buried or underwater environments.

Smart integration: compatible with SCADA/BMS systems for real-time pressure and flow monitoring.

Easy maintenance: modular designs and replaceable seals minimize downtime.

Comprehensive range: covering intake, transmission, treatment, and distribution systems.

5.Economic Benefits

Municipal operators adopting Dingliu’s valve solutions realize clear economic and operational gains:

Reduced pipeline leakage and water loss by 20–30%.

Extended valve life by 3×, minimizing replacement costs.

Lower energy consumption from optimized flow and reduced pump load.

Enhanced network reliability, improving public satisfaction and service continuity.

6.Environmental and Safety Impact

As cities worldwide aim for sustainability, Dingliu’s products contribute to greener, safer water management:

Leak-free operation reduces resource waste and supports water conservation goals.

Low-emission coatings and materials ensure compliance with RoHS and ISO14001.

Hydraulic and pressure-reducing valves protect pipelines and prevent bursts, ensuring operational safety.

Support for smart water systems enables predictive maintenance and reduces environmental impact.
