Gate valves remain the dominant isolation valve type in process plants, but the choice between solid wedge, flexible wedge, parallel slide, and expanding gate designs has profound consequences for performance…
Water utility valve selection must balance initial cost, service life, and whole-life maintenance cost across infrastructure that may remain in service for fifty years or more — the cheapest valve…
Gate valves are among the oldest and most fundamental components in industrial piping systems, yet they are frequently misspecified, misapplied, and misunderstood. As a full-bore, bidirectional isolation valve designed specifically…
Complete engineering guide to gate valves covering rising vs non-rising stem, wedge vs parallel slide vs slab gate designs, expanding gate valves, why they must not be throttled, and their…
Head-to-head comparison of cryogenic ball valves versus gate valves for LNG service. Covers thermal contraction behaviour, seat performance at -162°C, actuation requirements, extended stem design, BS 6364 testing, and total…
Complete guide to knife gate valves for slurry and wastewater service. Covers bidirectional and unidirectional designs, resilient and metal-seated options, actuator selection, and maintenance requirements for reliable operation in demanding…
Head-to-head technical comparison of gate valves versus ball valves. Covers pressure drop, shutoff performance, operating speed, temperature range, maintenance requirements, initial cost and total cost of ownership — with clear…
Choosing between globe valves and gate valves is a common challenge in piping system design. Globe valves offer superior flow control while gate valves excel in on/off applications. Learn which…
Gate valves require regular maintenance to ensure optimal performance and prevent costly failures. This guide walks you through the essential maintenance steps, including lubrication schedules, stem packing replacement, and leak…
