2-Way True Union Ball Valve

What is a Swing Type Check Valve?

Swing check valves are equipped with a disc that swings on a hinge or shaft. The flap swings away from the seat to allow forward flow of the media, and when the flow stops, the flap swings back to the seat to stop reverse flow. The weight of the valve flap and the return flow has an effect on the closing characteristics of the valve.

Swing check valves have a disc-shaped valve plate that rotates around the axis of the seat channel. Since the flow through the valve is streamlined, the flow resistance is smaller than that of lift check valves. Suitable for large diameter pipelines with small flow rates and large changes in flow compensation. Not suitable for pulsating flow, sealing performance can not be improved.

This type of valve should generally be installed horizontally in the pipeline.

Using different materials, swing check valves can be applied to a variety of media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, urea Such as chemical, pharmaceutical, fertilizer, electric power, and other pipelines.

Globe valve selection principle:

1. The check valve can be used in high-temperature and high-pressure pipelines of thermal power plants, nuclear power plants, and petrochemical systems.
2.Pipes that are not strictly required for flow resistance and have little consideration for pressure loss.
3. In urban water supply and heating, pipes with a diameter of less than 150mm can be installed with a shut-off valve to cut off and regulate.
