VPA series pneumatic pulse valve
Introduction:
VPA series pneumatic control pulse valve is the "switch" of compressed air in the injection and dust cleaning system of pulse bag dust collector. It is suitable for the connection between air storage cylinder and dust collector injection pipe. It is controlled by pneumatic signal to spray dust on filter bag.
Features:
1.The diaphragm is made of special rubber imported from Germany, with high pressure resistance and long service life.
2.The valve body and bonnet adopt die-casting process and surface electrophoresis treatment, with good anti-corrosion performance,compact structure and easy installation.
3.The internal flow channel of the valve body is optimized for large exhaust volume and rapid exhaust. The filter can be cleaned and the objects or workpieces can be blown away.
