In the installation process of ppr pipelines, in different areas, it is necessary to install water circuit stop valves. Many people wonder why various stop valves are installed in the distribution of water pipes. The stop valve of the ppr pipe mainly plays the following roles.

　　 One: Tangential flow

　　 The shut-off valve can cut off the direction of the water flow, and install the shut-off valve in a space. The flow rate of the shut-off valve is better than that of the gate valve. After the installation of a water pipe is completed, the water pressure test needs to be performed. At this time, there is no need to close the main valve, just close the single stop valve. In a fixed waterway, it can cut off the flow.

　　 Two: Throttling

　　 When the pressure of the passing water flow is too high, the inner wall of the ppr pipe will bear different pressures. The function of the stop valve is to intercept a part of the passing water flow and control the flow of the water flow. When the arrangement of water pipes is too complicated, a single shut-off valve plays a role in controlling the direction of water flow and throttling.

　　 Three: Split

　　 The loop of the water flow is too complicated, and check valves are used as the sign of the branch of the water pipe, and they are often used near the connection of the three-way joint. A water circuit loop where a check valve is located has a fixed water pressure value, forming a water flow branch.

　　The advantages of the globe valve

　　1: The shut-off valve is easy to install, it only needs to use the hot melt connection to connect with the ppr pipe, and it can play the role of water flow control.

　　2: The price of the shut-off valve is low. Compared with other control devices, it has better practicability and lower cost.
