Summary：

The diaphragm valve have a simple structure and small fulid resistance, in competence with the other types of valves, its flow capacity is larger under the same specifications; and nearly no leakage.The diaphragm isolates the powder or other materials from the stem cavity, so the leagage will not happen theoratically.

However, due to the limitations of the choices of diaphragm and lining materials, the pressure resistance and temperature resistance is only applicable under 1.6MPa nominal pressure and 150℃. The flow characteristics of the diaphragm valve is that approximately linear before 60% of the stroke, and the flow changes little after 60%.
