diaphragm valve

Descripción del producto

Type ZDGF－6/*0 pneumatic (electric) fluorine-plastic lined diaphragm valve is composed by pneumatic (electric) actuator and fluorine-plastic lined diaphragm valve. It receives air-source pressure signal (or telecom signal) of regulating instrument to open or close valve. As the parts connecting with medium adopt high-pressure plastic injection and are lined with anticorrosive, anti-aging PEP (F*6 for short) or PTFE (F4 for short), and the pump has the advantages of simple flowing route, no gland box, small resistance and large flowrate, it is widely used in chemical industry, petroleum, metallurgy, medicine, electric power and other industrial automatization system to cut off and regulate strong corrosive, high-viscidity, poisonous medium with grain or fabric. ●Characteristics： anticorrosive: Both interior cavity and globe body are lined with F*6 or F4, resistant to acid, alkali and strong corruption. good property of sealing: As adopt the structure of no gland box and use flexible diaphragm as throttling component, there is no leakage when closed. Large flow capacity: simple flowing route, small resistance, large flowing capacity; Ratio control: If matched with valve positioner, ratio control can be realized.
