Features：
● Short face-to-face length and easy installation.
● High corrosion resistance, Lightweight and cost- effective.
● UPVC, CPVC wafer check valve fully open angle is about 40°
● Due to the small inner diameter of PPH flanges, to obtain a larger opening angle, it is necessary to chamfer the flange or add a connection plate between the flange and the valve.

In modern industrial pipeline systems, reducing tees are important connecting components, and their maintenance is essential to ensure the efficient operation of the system. Regular inspection and maintenance can not only extend the service life of reducing tees, but also effectively prevent potenti...
In the modern industrial field, reducing tees, as important pipeline connection components, undertake the key functions of fluid transportation and distribution. Its design and material selection directly affect the overall performance and reliability of the pipeline system. Therefore, when selectin...
As a key component in the fluid control system, the performance of the manual diaphragm valve is directly related to the safety and efficiency of the entire system. As the core component of a manual diaphragm valve, the quality of its condition will directly affect the sealing performance and servic...
Maintenance and maintenance of manual diaphragm valves is the key to ensuring their long-term and stable operation, and regular inspections are the basis of maintenance work. It is crucial to conduct a comprehensive inspection of the valve's appearance, sealing surface, transmission components and c...
In industrial pipeline systems, stop valves are widely used in many fields such as petroleum, chemical industry, electric power, metallurgy and urban construction as a key control equipment. Stop valves are mainly used to cut off, adjust and throttle the medium in the pipeline. Their simple structur...
The superior performance of the stop valve in flow regulation is mainly due to the exquisite design of its valve disc. The valve disc moves linearly along the center line of the valve seat. This movement ensures the close fit of the sealing surface between the valve disc and the valve seat, thereby ...
