Eccentric Half Ball Valve Design & Industrial Applications
Quick Summary The eccentric half ball valve is a specialised industrial valve designed for demanding services where conventional ball or butterfly valves struggle. By combining an eccentric shaft with a half-ball geometry, this valve achieves low operating torque, excellent sealing performance and strong resistance to wear. In this guide, Vcore Valve explains how eccentric half […]
Lift Check Valve Structure, Working Principle & Applications
Quick Summary A lift check valve is one of the most reliable solutions for preventing reverse flow in pressurised pipeline systems. Unlike swing-type designs, it operates through vertical disc movement driven purely by flow dynamics and gravity. In this guide, Vcore Valve explains the structure, operating behaviour, performance characteristics and real-world applications of lift check […]
Single Disc vs Double Disc Gate Valves Explained
Quick Summary Discussing single disc vs double disc gate valves is not just about structure—it directly affects sealing performance, operating torque, and long-term reliability. At Vcore Valve, we often see gate valve failures caused by incorrect disc selection rather than material or pressure rating issues. This guide explains how both designs work, where each excels, and […]
V-Port Ball Valve: Advantages, Limits & Applications
Quick Summary Our V-port ball valve is widely recognised as a practical solution where accurate flow control is required but a full control valve may be unnecessary or too costly. At Vcore Valve, we often recommend V-port designs for applications demanding stable modulation, reduced cavitation, and improved controllability. This article breaks down how V-port ball […]
Rising Stem vs Non-Rising Stem Gate Valves Explained
Quick Summary Comparing rising stem vs non-rising stem gate valves is more than a visual preference—it directly affects installation space, maintenance strategy, safety, and long-term reliability. At Vcore Valve, we regularly see valve performance issues caused by incorrect stem selection. This guide explains the structural differences, operating principles, real-world applications, and selection criteria to help engineers […]
Knife Gate Valves-Everything You Need to Know
Quick Summary Knife gate valves are purpose-built for tough media such as slurry, pulp, powder and wastewater. Unlike conventional gate valves, their thin blade design allows them to cut through solids rather than fight against them. In this guide, Vcore Valve explains how knife gate valves work, where they perform best, where they fail, and […]
Wedge Gate Valve vs Slab Gate Valve: A Practical Guide
Quick Overview Discussing wedge gate valve vs slab gate valve is not just a matter of preference—it directly affects sealing reliability, maintenance cost and system uptime. At Vcore Valve, we see this decision made incorrectly far too often. This guide breaks down the real engineering differences to help you select the right solution with confidence. […]
5 Common Lug Butterfly Valve Installation Mistakes
Quick Overview Lug butterfly valves are widely used in industrial piping systems thanks to their compact design and end-of-line capability. However, many valve failures blamed on “poor quality” are actually caused by incorrect installation practices. From misalignment to improper bolt tightening, these mistakes can lead to leakage, seat damage, or premature valve failure. Drawing on […]
Industrial Valve Failures and Repair | Causes & Solutions
Quick Overview Industrial Valve Failures and Repair is important for industry. Industrial valves are designed to be robust, but they are not immune to failure. From leakage and sticking to complete operational breakdowns, industrial valve failures can disrupt production, compromise safety, and drive up maintenance costs. Understanding why valves fail—and how to repair or prevent […]
Ductile Iron vs Cast Steel Valves | Material Selection Guide
Quick Summary Comparing ductile iron vs cast steel valve in terms of pressure rating—it directly impacts safety, service life, and total operating cost. Ductile iron and cast steel are two of the most widely used materials for industrial valve bodies, yet they serve very different purposes. At Vcore Valve, we help engineers and project managers […]
