The electric diaphragm regulating valve is composed of two parts: an electric actuator and a diaphragm valve. The diaphragm valve has a valve body cavity with a smooth flow path, and has a large flow rate. The diaphragm is an elastic element, which functions as an adjustment, sealing and cutting. Stuffing box, simple structure, convenient maintenance, etc., the valve body can be lined with a variety of corrosion-resistant lining materials, the diaphragm can be rubber, PTFE, so this product can be widely used for the adjustment of strong acid, alkali, strong corrosive medium Also suitable for high viscosity, sewage treatment with suspended solids and granular materials

○ performance indicators
Note: Standard V-type PTFE filler is used.
○ Flow characteristic curve: approximate linear shape
○ Combination of valve body lining and diaphragm material
□ Electric actuator configuration and allowable pressure difference △ P
Note: 1. △ P is determined according to the valve closing P2=0.
2. △ P must not exceed PN. According to the user's conditions of use, the actuator configuration can be reduced or increased.
