Single Disc vs Double Disc Gate Valves Explained
Compare single-disc and double-disc gate valves by disc structure, sealing mechanism, operating torque, pressure sensitivity, maintenance, and application. Single-disc gate valves offer a simpler, lower-cost design for stable high-pressure and high-temperature service, while double-disc designs provide better low-pressure and bidirectional sealing for water supply, wastewater, and other pipeline isolation systems.
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.
