🔧 Installation Guide

 

Quick Installation in Three Steps

 

1. Connection Diameter → Check the thread compatibility and apply sealant
2. Manual pre-tightening → Tighten by hand for 3/4 of a turn to ensure no skewing.
3. Fix the tool → Use a torque wrench (recommended 35-40 N·m)

 

Installation safety reminder

 

• Do not use regular pipe tape; instead, use fire protection-specific sealant.
• The pressure gauge must be installed vertically upwards.
• The length of the immersion tube should not exceed 1.5 meters, which is the recommended value.

Q: Which specific fire extinguishing agents does it apply to?
A: It applies to:

• Inert gases: such as IG541 (a mixture of nitrogen, argon and carbon dioxide), IG100 (nitrogen) etc.
• Chemical gases: such as heptafluoropropane (HFC-227ea).
• Water-based medium: Clear water, high-pressure fine water mist.
• Foam: Partial foam concentrate.
• Not applicable to media: highly corrosive chemicals such as strong acids and strong bases.

Q: Can it be used on mobile fire trucks or portable fire extinguishing devices?
A: It is highly suitable.
Its brass material is corrosion-resistant and vibration-resistant. The compact integrated design (including the valve body, pressure gauge interface, and safety valve) saves space and is sturdy and reliable, perfectly meeting the requirements of mobile devices for high integration and high reliability of components.

Q: How to carry out daily maintenance and inspections?
A:

1. Visual inspection: Conduct monthly checks to ensure that the valves show no obvious mechanical damage, severe corrosion or signs of leakage.
2. Pressure gauge observation: If a pressure gauge is installed, regularly record the system pressure and confirm that it is within the normal range and there is no continuous decrease (there may be a minor leak).
3. Function check: Every year or in accordance with local fire regulations, the startup pressure of the safety valve should be verified, and a simulation test should be conducted to check if its operation is sensitive.
4. Reset: If the safety valve has ever operated and released pressure, it must be manually reset by professionals after the system's overpressure fault has been eliminated. Only then can the system be refilled and put back into use.
