Product description

The swing check valve belongs to the automatic valve category and is mainly used in pipelines where the medium flows in one direction. It only allows the medium to flow in one direction to prevent liquid backflow.

Customer challenge

Difficult maintenance

The structure of the swing check valve is relatively complex. If maintenance is required, more parts need to be disassembled, which makes maintenance difficult, takes a long time, and has a correspondingly high cost.

Large flow resistance and pressure loss

Since the valve disc, rocker arm and connecting accessories of the swing check valve rotate together, the weight of the valve disc assembly is relatively large, and the torque required to open is large. At the same time, the assembly occupies a large space in the channel, resulting in large flow resistance of the medium and large energy loss.

Poor sealing effect

Especially for gas media, the sealing effect of the swing check valve may be worse, and leakage problems may occur easily.

Product function

Convenient online maintenance and replacement

Low flow loss

Good sealing performance

The valve disc seal uses a rubber pad, which can be replaced and repaired online

Use an integrated valve disc to minimize the weight of the valve disc and reduce flow loss while ensuring sealing and fast closing

Rubber soft seal ensures qualified sealing performance

Value advantage

Akzo Nobel non-toxic anti-corrosion coating

The inner and outer surfaces of the valve are electrostatically coated with non-toxic epoxy resin powder. The coating is uniform, has strong adhesion, is anti-corrosive, and has a long life. It meets the ANSI/AWWA C550 standard and can be directly used in drinking water, food and medicine industries.
The closing time is short

The closing time is short, and the quick closing function can be achieved, with good energy-saving effect.
The valve body is light

The valve body is light, the valve disc has a short opening and closing stroke, a streamlined structure, and low flow resistance.
All castings are made of ductile iron

All castings are made of ductile iron, and the spheroidization rate reaches the international secondary spheroidization level, with high strength and good corrosion resistance.
