The body is made of high-grade ductile iron, which is about 20%~30% lighter than traditional gate valves, and is easy to install and maintain.

The pressure of the medium before and after the check valve is in a state of close balance and "sawing" with each other, the disc often beats with the valve seat, and the valve ...

In order to prevent the reverse flow of the medium, check valves should be installed on the equipment, devices and pipelines;

Do not let the check valve bear the weight in the pipeline system. Large check valves should be independently supported so that they are not affected by the pressure generated b...

The disc of the swing check valve is disc-shaped and rotates around the shaft of the valve seat channel.

Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the system pressure.

Check valve refers to a valve whose opening and closing parts are circular discs and rely on their own weight and medium pressure to act to block the reverse flow of the medium.

The main control parameters of the butterfly valve are the specifications and sizes.

The installation position, height, and entrance and exit directions must meet the design requirements, and the connections should be firm and tight.

During installation, the valve disc should stop in the closed position.

The rubber elastomer in butterfly valves will tear, wear, age, perforate and even fall off during continuous use.

Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, the robustness of the butterfly plate to w...
