Advantanges and disadvantages of PPR pipe valve stop valve


The feature of stop valve

1.beautiful appearance,easy installation,soft color,smooth inside and outside walls,small fluid resistance

2.good integrity,reliable quality,imported raw material as a whole processing,the interface is not easy to break and leakage

3.use 58 quality copper


The advantages of cut-off valve

1.In the process of opening and closing,the friction between the disc and the valve body is smaller than that of the gate valve,so it is wearable.

2.The opening height is generally only 1/4 of the seat passage,so it is much smaller than the gate valve.

3.Generally,there is only one sealing surface on the valve body and the disc,so the manufacturing process is better and the service is easy to maintain

4.Because the filling material is generally a mixture of asbestos and graphite,the temperature resistance grade is higher.Steam valves are normally used with stop valves.


Defects of stop valve

1.The medium through the flow of valve has changed,so the minimum flow resistance of the stop valve is higher than most other types of valves

2.Because the flow process is long,the opening speed is slower than the ball valve
