The 25-150KG Trolley Fire Extinguisher Valve 1100 requirements of a trolley extinguisher are different from those of a small portable extinguisher.
A 25-150KG trolley foam extinguisher contains a substantially larger quantity of extinguishing agent and is normally positioned on wheels so that the operator can move it to the fire location. The valve therefore needs to form a stable connection between the cylinder, pressure gauge, dip tube and discharge system.
The 1100 is specified for 25-150KG trolley extinguishers and provides a relatively large M52X1.5 cylinder connection.

This combination allows the valve to be integrated into a larger foam extinguisher assembly.
The product also includes a check valve. The supplied specification does not list a safety device for this model, so buyers should confirm the complete pressure-relief configuration of the finished extinguisher according to the target market's requirements.
The 25-150KG Trolley Extinguisher Valve 1100 is intended for large-capacity trolley foam extinguishers used where a portable hand-held extinguisher may not provide sufficient agent capacity.
Potential application environments include:
● Industrial facilities
● Warehouses
● Commercial premises
● Large equipment areas
● Locations requiring mobile high-capacity foam extinguishing equipment
The actual use should be determined according to the completed extinguisher's certification and foam-agent specification.
For large trolley extinguishers, dimensional compatibility becomes particularly important.
Before production, buyers should verify:
● Cylinder neck dimensions
● Inlet thread M52X1.5
● Dip tube diameter and length
● Gauge specification
● Discharge hose/nozzle connection
● Handle clearance
● Valve mounting orientation
● Complete extinguisher pressure requirements
A valve can be mechanically similar to another model while still being unsuitable for a particular cylinder. Drawing-based confirmation is therefore recommended for OEM projects.
Large trolley extinguishers are often stored for long periods before being required. Therefore, maintenance should not focus only on whether the valve can be opened.
● Inspection should include:
● External corrosion
● Thread condition
● Gauge condition
● Check-valve condition
● Discharge connection
● Signs of leakage
● Mechanical damage
Regular inspection is especially important for equipment stored in industrial or outdoor environments.
