Specialty Check Valves: Single Plate, Lift, and Tilting Disc for Transient Flow

Standard Swing and Dual Plate Check Valves are common, but high-velocity, high-pressure, or slurry-laden systems demand specialized solutions. The Single Plate Check Valve offers robust, low-pressure-drop performance, while Lift Check Valves excel in small-bore, high-velocity lines. This technical guide explores advanced check valve designs engineered to manage severe transient flow and significantly reduce the damaging effects of water hammer in critical industrial pipelines.

Solving the Problem of Gland Packing Leaks in Industrial Gate Valves

Leave a Comment / Blog / Metflow Engineers

Gland packing leaks are the most frequent source of fugitive emissions and fluid loss in industrial plants, especially with high-cycle valves like Gate Valves. The root cause is rarely the packing material itself; it’s usually improper installation, thermal shock, or incorrect gland bolt torque. This guide provides maintenance engineers with actionable steps to diagnose and solve stem leakage, ensuring your Stainless Steel Gate Valves maintain a reliable seal and uphold environmental compliance.

Wafer vs. Lugged Butterfly Valves: Why Compact Valves Are Ideal for Large-Diameter Pipes

Leave a Comment / Blog / Metflow Engineers

When dealing with large-diameter pipelines carrying non-corrosive fluids at low pressure, Butterfly Valves offer a superior combination of cost-effectiveness, compact design, and ease of operation. Unlike heavy, bulky Gate Valves, the butterfly’s quarter-turn operation and lightweight profile make it the preferred choice for utilities. Compare the installation differences between Wafer Type (for cost savings) and Lugged Type (for dead-end service) to optimize your industrial utility lines.

Globe Valves: The Unmatched Champion for Throttling and Flow Regulation

Leave a Comment / Blog / Metflow Engineers

When precise control over flow rate is required (a process known as throttling), the Globe Valve is the undisputed industrial champion. Unlike Ball or Gate valves that are strictly for on/off service, the Globe Valve’s design minimizes the erosive damage typically caused by partially open flow. Learn how the globe valve’s unique internal structure makes it ideal for managing pressure drop and flow in critical applications like steam and chemical processes.
