QA-Y- 76S Pneumatic Pulse Valve Similar To Asco Pulse Valve 3 " Port Size

Usage

Electromagnetic valve ( Also called diaphragm valve ) is the” switch “for compressed air in the dust clean blowing system of the pulse bag filter . Controlled by the output signals of the pulse jet control device , it makes dust clean to the filter bags cell by cell to keep the resistance of the baghouse within the set range and thus guarantee the processing functions and the dust collecting efficiency of the baghouse .

Y type electromagnetic pulse valves is a suble for the work occasions embedded valve ) , is directly installed in the gas bag , with better flow characteristics . As pressure losses drops , it will be suitable for the work occasion of loser pressure gas source .

Working Principle

The electromagnetic pulse diaphragm valve is composed of two gas cells . When the compressed air is connected , it comes into the back bags cell though the orifice , the pressure in the back gas cell pushes the diaphragm against the outlet of the valve and the electromagnetic valve stays in the “ closed ” condition .

When the electromagnetic pulse valve returns to its original position .

The air escape of the back gas cell closes and the pressure in the back gas cell cell rises , which pushes the diaphragm closely again .

The electrical signals from the pulse jet control device move the armature of the electromagnetic pulse valve . The air escape of the back gas cell opens and the back bag gas cell loses pressure quickly , thus the diaphragm moves back and the compressed air blows through the valve outlet . The electromagnetic pulse valve comes into the “ open ” condition .

Pulse valve is composed of pilot head, diaphragm and valve aluminum body. The back cavity area of diaphragm is bigger than the front one. The diaphragm is kept at the closed position due to the effect of big pressure.
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.

Q: Is there a warranty available?

A: Yes, normally products is one year quality guarantee.

Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?

A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect

G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America

Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?

A: 1MPa=10bar≈145psi≈10kg

Q:What usually causes the burnout of solenoid valve coils?

A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.

Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
