FAQ
01.Are there different sizes of interfaces available for selection?
02.What should be noted when installing a pressure gauge?
- Use the appropriate sealing material
- Do not over tighten. The recommended torque is 15-20 N·m.
- After installation, a static pressure test should be conducted.
03.How to handle the situation when is difficult to open?
- Check if the handle is deformed or damaged
- Confirm whether the system pressure has been completely released.
- Proper lubrication should be applied to the stem area (using a dedicated silicon based lubricant)
04.Why does the safety valve frequently release pressure?
- The system pressure has exceeded the set value (check the filling pressure)
- Safety valve spring is fatigued (needs replacement)
- The valve seat sealing surface is damaged (requires professional repair)
- The change in environmental temperature leads to fluctuations in pressure (which is a normal phenomenon)
05.What should be noted when using in a low-temperature environment?
- Confirm that the sealing material is suitable for low temperatures (standard product is applicable up to -30°C)
- Check if the valve is frozen before operation
- Consider installing insulation measures
- Prevent the failure of the seal due to rapid temperature changes
06.Is it compatible with all types of fire extinguishing agents?
