Wafer check valves offer a space-saving, efficient solution for backflow prevention in demanding industrial systems. This article explores how they work, their key benefits, and why QRC’s new Chaoda dual plate design is a smart addition for modern fluid applications.

Floating ball valves offer tight shutoff and cost-effective performance in gas and liquid systems across multiple industries. This article breaks down how they work, their key features, material options, benefits, and how they compare to trunnion-mounted valves. It also covers industry standards, design considerations, and maintenance best practices for long-term reliability.

This article explores the different types of shut-off valves, including manual, automatic, and excess flow valves, their applications in industrial and residential settings, and key selection factors. Additionally, we’ll discuss compliance with industry standards and how QRC Valves offers high-quality solutions for safe and efficient natural gas operations.

Valves are essential to pulp and paper operations, where harsh chemicals, abrasive slurries, and high temperatures are the norm. This article explores the most common valve types in the pulp and paper industry and their roles in pulp digestion, chemical recovery, and water treatment. We’ll also examine important selection factors, including material compatibility, durability, and maintenance requirements for maximum reliability in this demanding sector.

API 600 and API 602 are key valve specifications used in industrial applications, particularly in the oil and gas sector. This article explores the differences between these standards, including their design scope, pressure ratings, materials, and typical applications. API 600 covers larger bolted bonnet gate valves, whereas API 602 applies to compact forged steel valves. We’ll also discuss selection factors and compliance requirements.

Gaskets play a vital role in oil and gas applications by ensuring leak-proof seals in piping, flanges, and equipment, especially those that experience high pressures and extreme temperatures. This article explores the various types of gaskets in the industry, including spiral-wound, ring-type joint (RTJ), Kammprofile, and non-metallic gaskets. We’ll also discuss material selection, industry standards, and best practices for installation and maintenance. Learn how choosing the right gasket can enhance system integrity and reliability in demanding oil and gas environments.

The design of ball valves enables them to provide reliable sealing, but leakage can occur due to a variety of conditions. This article explores the common causes of ball valve leakage, leakage types, how to detect and fix them, as well as the different leakage classes.

Valves are crucial components in fluid handling systems, ensuring proper flow control and protecting equipment from damage due to backflow. Among the many types of valves, non-return valves and check valves are often mentioned together, leading to confusion about their distinctions. While both have a design to allow fluid to flow in only one direction, their construction, applications, and terminologies vary. In this article, we will explore the non-return valve vs check valve debate in depth, examining key differences, and how to select the right valve for your system.

Among the various valve types, gate valves, globe valves, and check valves are some of the most common. Each serves a unique purpose with a design to address specific operational needs. In this article, we compare the design, function and applications of the gate valve vs globe valve vs check valve.

In downstream oil and gas operations, valves are essential for controlling fluids’ flow and pressure during refining, distribution, and storage. This article reviews common types of valves for the downstream oil and gas industry, and factors influencing their selection.
