Generally, valve testing simulates operating conditions in a controlled environment to ensure fit for service valves. However, testing also occurs periodically after installation in line with standard practices. In this article, we will review common valve testing types and industry standards that offer guidelines for valve testing.

A swing check valve allows forward flow and blocks the reverse flow. It provides a strong option for uni-directional homogenous flow applications. In this article, you will review a swing check valve diagram, operating principles, types, k-values, installation concerns, and applications.

Valve trim refers to the operating parts of a valve that are usually exposed to the process fluid. In this article, you will learn more about the meaning of valve trim, review a valve trim chart, learn about the material selection process, and review the selection process in action by comparing two common trims: trim 5 vs. trim 8.

Hydrogen Induced Cracking is a unique mechanical failure model common in low alloys and high-hardness steel grades such as titanium. In this article, you will learn what hydrogen-induced cracking (HIC) is, how to avoid hydrogen-induced cracking, detection tests, and repair methods.

The API Monogram Program verifies that manufacturers produce equipment in accordance with applicable API specifications and maintain a quality management system that meets API Spec Q1 requirements. This article explains the certification process, the valve standards covered by the program, how to verify licensed manufacturers, and why API Monogram certification matters when selecting industrial valves.

Killed steel is fully deoxidized before casting, creating a dense, uniform material with fewer internal voids and improved structural integrity. This article explains how killed steel is produced, the role of aluminum and other deoxidizers, common carbon steel grades, and its use in industrial valve manufacturing.

Blowdown service refers to the process of removing hot water from the bottom of a boiler to reduce the accumulation of dissolved solids in the boiler water. These solids, if left unchecked, can affect boiler efficiency, therefore, cause scaling, and lead to operational issues. During this process, the hot water is rapidly vented to the

HYDRO TESTING – CLASS I to IVCLASS SEAT LEAKAGE The term “Class” seat leakage comes from ANSI/FCI 70-2, a specification that applies exclusively to control valve seat leakage. It does not apply to gate or globe valves, which typically serve in on/off service rather than throttling applications. Despite this distinction, some end users mistakenly specify

Understanding the 3-Line Bypass and Equalizer Combination in Gate Valves A 3-line bypass and equalizer combination plays a crucial role in ensuring safe, efficient valve operation in high-pressure systems. This design allows users to warm downstream piping, reduce torque requirements, and prevent overpressurization within the valve body. In this article, we will explore how the
