DMF Electromagnetic Pneumatic Pulse Valve Air Dust Proof Valve industrial environment health Application

QD - Z - 40S / 50S Series Electromagnetic Pulse Valve GOYEN Replace G1 - 1 / 2 " , G2 " Dust proof valve Dust Control Valve



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 thebaghouse within the set range and thus guarantee the processing functions and the dust collecting efficiency of the baghouse .


Z type electromagnetic pulse valves is a right angle valve , with the 90 degree , angle between the inlet and outlet , which is suitable for the installation connection between the gas dome and the baghouse blow tube provide good air flow and dust clean pulses satisfying the requirements .

During installation and commissioning

Failure phenomena

1 . The valves cannot all be opened, but the leading part does act.
2 . Some valves do not work, but the others are normal.
3 . The valves cannot all be closed. There is leakage. There is no way to establish a gas dome.
4 . Some valves cannot be closed. There is leakage.
5 . A valve closing is slowly.

Possible Reason

1 . Check the gas dome pressure to see if it is too low.
2 . Check the valve coil connection and coil
3 ( 1 ) . Y-valve. Some valves for the same gas dome are leaking, thus causing leakage for all the valves.
3 ( 2 ) . Z-valve. The valve inlet and blowing muzzle are installed backwards.
4 . There is some dirt or debris on the membrane, ii is blocking the moving iron core.
5 . The membrane orifice is blocked.

Troubleshooting

1 . Check the leakage
2 . Replace the accessories
3 ( 1 ) . Check the leakage
3 ( 2 ) . Re-install
4 . Clean the membrane and check that the membrane is complete. Check the moving iron core and air lock.
5 . Dredge the membrane orifice


During use period

Failure phenomena

1 . Some valves are leaking. The membrane cannot close tightly and the valve is always open a
little.
2 . Coil is hot and burned out.
3 . Voltage exists but the valve does not operate.
4 . Ambient temperature is below -20℃. The valve is leaking and cannot open.

Possible Reason

1 . There is some dirt or debris on the membrane, the leading part is damaged. Moving iron core is blocked.
2 . It has been turned on for too long.
3 . Membrane is damaged and the orifice is blocked.
4 . Ambient temperature is too low and here is frost in the valve.

Troubleshooting

1 . Clean the membrane and check that the membrane piece is complete. Check the moving iron core and the air lock. Replace the accessories if necessary.
2 . Check the working condition of the control system.
3 . Replace the accessories in time.
4 . Pay attention to insulation and maintaining proper temperatures.

Q: Could you offer the free samples ?

A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055

Q: What ' s your business scope ?

A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .

Q: What types of products you can make ?

A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .

Q: Can the product be made with our logo and brand ?

A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .

Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ?

A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,Siemens,Rosemount,Marsh ,Endress+Hauser etc.

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?
