3/4'' NBR Diaphragm For WUXI YONGDA WXYD TDF-K20 Pulse Jet Valve​

The diaphragm is the most important part of the pulse valve. When the pulse valve is energized, the trapped air above pulse valve diaphragm is quickly exhausted causing fast opening of main diaphragm valve. When the pulse valve is de-energized, air escapes through bleed hole of main pulse valve to balance the diaphragm pressure and instantly closes the pulse valve.
