This article provides a comprehensive guide to gate valve installation, tailored for industrial professionals. It begins with a clear overview of gate valves—their design, types, and key functions in fluid handling systems. The guide then details the five most common installation mistakes, including improper pipe support, flange misalignment, inadequate cleaning, incorrect bolt torque, and wrong valve orientation, explaining the risks and consequences of each error. Finally, it offers practical, step-by-step best practices to avoid these mistakes, ensuring gate valves operate reliably, safely, and efficiently for long periods. Whether you’re an installer, maintenance technician, or industry professional, this guide helps prevent costly downtime and premature valve failure.

This article compares ball valves and gate valves to help industrial users make the right choice and avoid costly or safety risks. The article explains their structures and principles: A ball valve consists of a ball with a hole, a valve seat, a stem, and an actuator; a 90° rotation of the stem enables rapid opening and closing. A gate valve consists of a gate disc, a valve stem, and a handwheel; raising and lowering the gate disc provides precise linear flow control. The article also lists their applications: Ball valves are suitable for the oil/gas, water treatment, and chemical industries. Gate valves are used in power systems and municipal engineering.

This article clearly explains the core differences between brass gate valves and globe valves, covering their working principles, structural features, and applicable scenarios. Gate valves are designed for full-open/full-close isolation, providing an unobstructed flow path; while globe valves are used for precise flow regulation, offering better throttling performance. Correctly selecting the valve type is crucial for preventing leaks and ensuring long-term reliable system operation. WESDUN, as a professional valve manufacturer, provides selection guidance and high-quality industrial valve solutions.

This article focuses on the application value and development trends of butterfly valves in water and wastewater treatment, providing an in-depth analysis based on WESDUN's technological innovation practices. It begins by introducing the core principles of butterfly valves, highlighting their advantages over traditional valves, such as compact structure and quick operation, and illustrating their adaptability in scenarios like high-flow control and corrosive media transportation through practical examples. Then, it elaborates on the five core advantages of butterfly valves: space adaptability, emergency response efficiency, full life-cycle economics, multi-material compatibility, and low-resistance energy-saving characteristics. It emphasizes WESDUN's technological breakthroughs: using duplex stainless steel 2205 and tungsten carbide spraying to enhance durability, an innovative triple-seal structure to achieve zero leakage, customized solutions for high-altitude and seawater desalination applications, and global compliance certifications to ensure safety.

This article answers the question, "Can butterfly valves be used for gas?" with a definitive answer, while also clearly stating that not all butterfly valves are suitable. It categorizes gas butterfly valves based on connection method and seal type. It also details the advantages, safety requirements, practical applications, and maintenance techniques of these valves. The article concludes that, with proper selection, adjustment, and maintenance, gas butterfly valves are a safe and cost-effective option for gas systems.

This article details the working principle of a check valve, which uses fluid pressure (or gravity) to open or close internal moving parts (such as the disc and ball), similar to a one-way door. It also lists the working principles and application scenarios of different types of check valves, and cites their widespread applications in the home, automotive, and medical fields. It emphasizes their importance in preventing pollution and protecting equipment, as well as key maintenance points such as regular cleaning and component replacement.

International Water Treatment Exhibition

This article focuses on the double eccentric (double offset) butterfly valve, a high-performance flow control component widely used in global industrial sectors. It first explains the valve’s core double eccentric structural design and working principle, highlighting how its two key offsets reduce wear and improve operability. The article then details its distinct advantages, including minimal wear, low operating torque, premium sealing, wide compatibility, and cost efficiency. It also outlines core global application scenarios across water treatment, oil & gas, power generation, and chemical manufacturing, followed by practical selection guidelines to ensure optimal performance. Finally, it recommends WESDUN’s high-quality products that meet international standards, aligning with the valve’s performance and application needs.

From September 5 to 7, 2019, WESDUN participated in EXPO NACIONAL FERRETERA held at the Exhibition Center in Guadalajara, Mexico. As a leading Latin American hardware and construction exhibition, the event helped WESDUN showcase professional valve and pipe fitting products, connect with local industry buyers, expand Latin American market channels, and enhance global brand influence.

This article compares gate valves and butterfly valves, two essential components for industrial fluid control systems. It details their basic definitions, core structural features, and key advantages—covering operation speed, installation convenience, cost efficiency, sealing performance, and maintenance requirements. Additionally, it clarifies the suitable working conditions and typical application scenarios for each valve, and provides clear, practical guidance to help industrial users select the right valve based on their specific project needs and operational environments.

This specification summarizes eight standardized requirements for gate valve installation, covering hoisting protection, mounting direction, opening/closing rules, lubrication, cleaning, bolt fastening and packing inspection. It forbids lifting valves via handwheel and requires vertical installation for double gate valves. The valve can only be fully opened or closed by original handwheel instead of extra levers to protect sealing faces. Besides, cavity and sealing surface cleaning, even bolt tightening, regular lubrication on stem threads and rotating parts as well as qualified packing compression are mandatory during installation to prevent damage, corrosion and leakage of gate valves.

This document provides an overview of gate valves, which control fluid flow in pipes using a gate. It explains their components and outlines signs of damage， It also details emergency steps for a broken valve. Additionally, it offers tips for choosing a good gate valve, including considering material , proper sizing, quality brands (e.g., WESDUN), certifications (like ASME), usage frequency, and easy operation.

This article is tailored for industrial professionals, covering key aspects of globe valves including operational principles, correct installation steps, routine maintenance notes, and common fault repair methods. It elaborates on solutions to typical issues like internal/external leakage, stuck handwheels, and vibration, aiming to help professionals ensure system reliability, extend globe valve service life, and minimize downtime.
