Valve end connections establish the critical interface between valves and piping systems, and they influence how securely each valve performs in service. This article explains the major connection types and outlines when engineers should use each option based on pressure, temperature, medium, installation, and maintenance requirements.

Degassing valves automatically vent gas pockets and microbubbles while keeping liquids contained, which protects pumps and stabilizes hydraulic performance. They reduce cavitation risk, prevent airlocks, improve measurement accuracy, and slow oxygen-driven corrosion, making pipelines safer and more reliable.

Plug valves and ball valves may look similar from the outside, yet their design and sealing methods create very different performance profiles. This article highlights those differences to help engineers match each valve to the right process conditions.

Cast steel valves deliver strength, leak-tight performance, and adaptability in the most challenging industrial environments. This article explores their design, advantages, and applications.

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.
