Product Description

Why do you need a swing check valve?

The swing check valve is used in various mediums like steam, water, nitric acid, oil, solid oxidizing media, acetic acid, and urea. These are generally used in chemical, petroleum, fertilizer, pharmaceutical, power, and other industries. However, these valves are suitable for cleaning and not for those mediums that contain very high impurities. These valves are also not recommended for mediums that are pulsating. We are one of the top swing check valve suppliers who produce superior quality valves.

The lip seal present on the disk makes sure that it is not loose.
The disc or bonnet design makes it easy to maintain
The disc on the valve can move slightly both vertically as well as horizontally close properly.
When the disk is light in weight, it requires minimum force to close or open the valve.
A hinge around the shaft with strong bones ensures the durability of the valve.
Swing type check valves are designed so as to prevent the medium in the pipe from flowing backward. When the pressure becomes zero, the valve shuts down completely, which prevents the backflow of materials inside the pipeline.
Turbulence and pressure drop in swing-type wafer check valves are very low.
These valves are to be installed horizontally in the pipes; however, they can also be vertically installed.
Equipped with a weight block, it can quickly close in the pipeline and eliminate destructive water hammer

Product wireframe

When media is being pumped from a suction reservoir to a discharge reservoir, reverse flow is highly likely to occur when the pump is stopped. Check valves are used to prevent this. The valve type commonly used for this is the foot valve.

A check valve comprises two ports – an inlet and an outlet – and a shutoff/closing mechanism. The unique characteristic of check valves that distinguishes them from other types of valves such as ball and butterfly valves is that, unlike these valves that require some form of actuation to operate, check valves are self-operating. Check valves function automatically, relying on differential pressure to effect control. In their default position, check valves are closed. When media flows in from the inlet port, its pressure opens the closing mechanism. When the inflow pressure drops below the outflow pressure due to flow being shut off, or the pressure on the outlet side becomes greater for any reason, the closing mechanism immediately closes the valve.
