Gate valves are among the most widely used isolation valves in industrial piping. When fully open, the gate lifts completely out of the flow path, so the valve offers straight-through flow with very low pressure drop. This makes gate valves the preferred choice for on-off service in water, oil and gas, steam and process lines. This guide explains the main gate valve types and gives you a practical checklist for selecting a quality valve that lasts.

Ball valves are the workhorses of modern industrial piping. With a simple 90-degree turn, they deliver tight shut-off, low pressure drop and long service life in water, oil and gas, chemical and HVAC systems. Yet not all ball valves are alike: the right choice depends on pressure, temperature, media and how the valve will be installed. This guide breaks down the main ball valve types and gives you a practical checklist for selecting a quality valve that lasts.
