Embedded Type

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.

Common failure and troubleshooting                                                                                                             

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?
