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 h
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat
