The advantages of the ball valve: the structure is simple, the weight is very light, the sealing performance is good, the operation is convenient, the switch is fast, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace. Disadvantages of the ball valve: the flow cannot be adjusted, and it is not suitable for higher temperatures due to the limitation of the sealing material. The gate valve is driven by the valve stem to complete the opening and closing of the gate valve, and it has good sealing performance and small flow resistance, that is, the opening and closing speed is slow. In the ball valve, the valve plate rotates 90° around the valve shaft to complete the opening or closing, and the ball valve is not suitable for use in high temperature. If it is easy to be blocked by impurities for a long time, the valve cannot be opened. Therefore, it is recommended that you install a gate valve on the heater.
