Cylinder Valve | Core Control Component for Gas Fire Suppression System Cylinders
Cylinder Valve | Core Control Component for Gas Fire Suppression System Cylinders
Product Overview
The cylinder valve is installed on the neck of agent storage cylinders or pilot gas cylinders. Under normal conditions, it maintains a tight seal to prevent agent leakage. When a fire occurs, the valve is opened pneumatically or manually to release the extinguishing agent. Xingjin cylinder valves feature a nitrile rubber cone seal structure, equipped with a pneumatic activation port and a manual emergency opening device, suitable for various piped and pipeless fire suppression systems, meeting the high safety requirements of commercial and industrial facilities.
Applicable Places
Xingjin cylinder valves are widely used in the following commercial and industrial applications:
-
Data Centers & Server Rooms – Long-term leak-free sealing is critical for cylinder valve reliability
-
Power Distribution & Transformer Rooms – Complex environments require excellent corrosion resistance and sealing
-
Telecom Base Stations & 5G Rooms – Unattended sites require long-term stable standby
-
Generator Rooms & Oil Storage Areas – High-risk areas require reliable emergency valve opening
-
Industrial & Chemical Plants – Multiple cylinder systems require each valve to be independently reliable
-
Libraries, Archives & Valuable Storage – High-reliability systems rely on cylinder valves as core protection components
