Rising Stem Gate Valves: OS&Y Design, Features and Selection Guide
Learn how rising stem gate valves use visible stem movement to indicate valve position and support safer pipeline isolation. The guide explains OS&Y gate valve construction, rising stem operation, differences from non-rising stem designs, space requirements, maintenance visibility, high-pressure service considerations, and key selection factors for oil and gas, steam, water, power, and above-ground industrial pipeline 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.
