The choice of ball valve or angle valve in the heating pipeline depends on specific needs:

Ball valve

Advantages: High flow rate, fast switching, good sealing performance, suitable for scenarios that require quick adjustment and high flow rate.

Disadvantages: Unable to finely adjust flow rate, and may require higher sealing performance under high temperature and pressure.

Applicable scenarios: The main inlet or main pipeline of the heating system, which requires high flow and fast switching.

Angle valve

Advantages: It can finely adjust the flow rate, change the direction of water flow, and is suitable for installation environments with limited space.

Disadvantages: High water flow resistance and relatively low flow rate.

Applicable scenarios: Branches of heating pipes or areas where flow needs to be adjusted, such as radiator connections.

In summary, if high flow and fast switching are required, choose a ball valve; If you need to finely adjust the flow rate or change the flow direction, choose an angle valve.
