Check Valves

Swing Check Valve

Product model: H44T-10/16

Swing check valve is also called one-way valve or check valve, its function is to prevent the medium in the pipeline from flowing back. The valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back is called a check valve. Check valves belong to the category of automatic valves. They are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents.

Swing check valve is suitable for nominal pressure PN0.6MPa~42.0MPa, Class150-2500; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540℃ on various pipelines to prevent the medium flows back. By selecting different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea.

Lift Check Valve

Product Model: H41T-6/10/16

Lift check valve refers to the valve that automatically opens and closes the valve flap depending on the flow of the medium itself, and is used to prevent the medium from flowing back. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent the medium from flowing back, preventing the pump and drive motor from reversing, as well as the release of container medium. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Wafer Butterfly Check Valve

Product Model: H77X-6/10/16

Wafer butterfly check valve is a kind of valve that is used to prevent the back flow of the medium in the use of pipelines and equipment. The structural length of the valve body is a short series, with good rigidity, easy installation, completely reliable performance and good anti-interference. The design of the butterfly plate adopts two torsion springs on the mating plate, which can make the valve plate open and close automatically within the pressure range. Different types of glue and other components can be selected according to the needs of users.

Internal Thread Swing Check Valve

Product Model: H11T-6/10/16

Internal Thread Straight-through Check Valve

Product Model: H14T-6/10/16

The nature and function of the internal threaded check valve are the same as the above-mentioned check valve, except that its two ends are not flanged, but threaded. In general, the size of the threaded check valve is below DN50.
