| QG-1/QG-2 |
cylinders with valves,fitted with throttle,speed regulation,buffer mechanism,are of compact structure, easy of use, resistant to high temperature, exerting great striking impact and highly reliable.These two varieties are mainly used in aluminum factory for material feed and aluminum tapping of the electrobath tank and arenecessary pneumatic elements in automated production of an aluminum factory |
| QG-22 |
This breaking cylinder have special mechanical device to avoid drop suddenly.Features automatically air pressure transfer between high pressure and lowpressure, with singnal feed back system.When the low pressure break the shell successfully,the sensor send the singnal which make the rod extension. If not,the sensor do not send the singnal. Then system willtransfer low prossure to high pressure until thecy linder breaktheshel.If it can not break the shell the system will alarm |
| QG-3/QG-4 |
Those are light anti-falling cylinders without valves fitted with auto shaft-pin locking device thatprevents piston rod from falling by itself.when the cylinder is vertcally in staled and air supply cut off the pison will not fall by itself thank to the locking device and this well meets the needs of the electrobath tank's operation. |
| QG-5/QG-6: |

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?
