DB120 G3" Diaphragm Repair Kit

DB120 G3" Diaphragm Repair Kits pulse solenoid valve With SS spring

Ordering Code: DB120
Material: Nitrile/Buna
Nitrile is for -10~80°C working temperature.
FKM is for -10~200°C working temperature.
The diaphragm is fit for the FLY/AIRWOLF pusle valves: VNP220 , VEM220 , VNP320 , VEM320, VNP420, VEM420, VNP620, VEM620, VNP620, VEM720
The 200 Series is available in the following versions:
• VNP,with integrated solenoid pilot
• VEM,with remote pneumatic connection.
We use high quality material , the collection equipment efficiency can be improved , the energy loss also can be reduced.

Reminder:
* Diaphragm and pilot inspection should be conducted once a year.
* Ensure that components are completely isolated from pressure and power before any maintenance activities are performed on the system. Do not reapply pressure and power until the valve is fully assembled.

Pulse jet valve

1. Used outside of bag-type duster sack-duster’s blowing and cleaning ash.

2. Adopte this kind of structure that submerge in the air porket..

3. Compare to other structure, reduce resistance in interval channel and pressure of blowing supplier.

4. So it adapt siuation of low pressure, reduce energy consumption and prolong membrance patch using.

Metial: Nitrile or Common rubber

Use:For the Pulse Jet Valves

 

Diaphragm itself operating temperature range and pressure range depends on the types of plastic , fabric and structure. The diaphragm can be operated at -50 to 100 ° C , 0.4 ~ 0.8MPa conditions ; fluorine rubber and silicone rubber diaphragm 232 can work in -80 degrees Celsius . Epichlorohydrin rubber diaphragm can work under pressure 0.4 ~ 0.8MPa , air tightness, anti-aging , longevity and engine overhaul life equal.

Introduction
Electromagnetic pulse valve refers to the gas through the valve in instantaneous once a electrical signal received. Just like pulse phenomena, it has the change of the short fluctuation. Therefore it is calls the pulse valve. The Industry standard definition of electromagnetic pulse valve for electromagnetic pilot valve and pulse valve together, diaphragm valve controlled by electrical signals.

 

Working principle
Electrical pulse controller send input signals so that the electromagnetic armature attracts the moving bar. Unclose the balancing hole to release the pressure gas in the back cavity of diaphragm quickly; the pressure gas in the front cavity holds up the diaphragm to open the passage and the valve starts cleaning.
The pulse signal disappears and the spring of the armature works immediately to resume the moving bar so as to close the balancing hole. The pressure gas in the back cavity of the diaphragm and the spring work together to close the passage the valve stops cleaning.
The damping hole in the diaphragm functions to damp the airflow when the moving bar of armature holds up for balancing and to transit the air to the back cavity as soon as the balancing hole is shut to close the passage and stop cleaning.
