Gate Valves for Water and Wastewater Systems: Applications and Selection Guide
Learn how gate valves are used in water and wastewater systems for pipeline isolation, maintenance shutdowns, low-resistance full-open flow, and reliable shutoff in municipal water networks, treatment plants, and industrial utility lines. The guide explains key selection factors such as resilient-seated design, ductile iron construction, epoxy coating, corrosion resistance, wastewater service conditions, AWWA-related standards, and proper on/off operation.
Gate Valve: 5 Types, Parts, and Working Principle
Explore the main gate valve types, components, and operating principle, including wedge, parallel-slide, resilient-seated, metal-seated, rising-stem, and non-rising-stem designs. The guide explains how gate valves provide full-open or full-closed pipeline isolation and highlights key selection factors such as seat construction, body material, pressure and temperature, media compatibility, actuation, maintenance, and applicable standards.
