Differences between Rising Stem Gate Valves and Non-Rising Stem Gate Valves

Differences between Rising Stem Gate Valves and Non-Rising Stem Gate Valves 2024.03.25

In a rising stem gate valve, the stem moves up and down as the valve is opened or closed. When the valve is opened, the handwheel is turned, causing the threaded stem to rise. As the stem rises, it lifts the wedge, allowing fluid to flow through the valve.

KV value flow coefficient of the stop valve

KV value flow coefficient of the stop valve 2024.02.19

The KV value (also known as the flow coefficient or CV value in some regions) of a valve is a measure of its flow capacity. Specifically, it represents the volume of water in cubic meters per hour (m³/h) that will pass through the valve with a pressure drop of 1 bar (100 KPA or approximately 14.5 psi) across the valve.
