Swing Check Valve Product model: H44T-10/16
Swing check valve, also known as one-way valve or non-return valve, is used to prevent the backflow of media in the pipeline. The opening and closing parts are opened or closed on the basis of medium flow and force. The valve that prevents the back-flow of medium is called the check valve. Check valve belongs to automatic valves. It is mainly used for pipes with unidirectional flow of media. To prevent accidents, medium is allowed to flow in only one direction.
The swing check valve is suitable for various pipelines with the nominal pressure PN0.6MPa~42.0MPa, Class150-2500, nominal diameter DN15~1200mm, NPS1/2~48, and working temperature 196~540℃, and it is used to prevent the back flow-of medium. By selecting different materials, it can be applied to many kinds of media, such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium 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 disc depending on the flow of the medium itself to prevent the backflow of the medium. It is also known as check valve, one-way valve, reverse flow valve and back pressure valve. The check valve belongs to an automatic valve, which is mainly used to prevent medium backflow, reverse rotation of pump and driving motor, and discharge of container medium. The check valve can also be used on the pipeline to supply the auxiliary system in which the pressure may rise above the system pressure. Check valves can be mainly 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: DH77X-6/10/16
The wafer butterfly plate check valve is a valve used to prevent backflow of media during usage in pipelines and equipment. The face-to-face dimension of the valve body is short series, the rigidity is good, the installation is convenient, the performance is completely reliable, and the anti-interference is great. The design of the butterfly plate uses two torsion springs on the dual plate to automatically open and close the valve plate within the pressure range. Different types of rubber 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 thread check valve are the same as the check valve described above, but its two ends are not flanged, but threaded. Generally, the specification of threaded check valve is below DN50.
