4-9kg Powder Extinguisher Valve

The 4-9kg Powder Extinguisher Valve 1101E occupies the middle-capacity range between compact 1-2KG extinguishers and large trolley units.

For 4-9KG foam extinguishers, the valve has to provide sufficient flow connection while remaining suitable for a portable extinguisher assembly. The 1101E uses a copper-alloy construction and provides three important connection interfaces: cylinder inlet, outlet and dip tube.

Its specified connections are:

● Inlet: M30X1.5

● Outlet: M14X1.5

● Dip tube: M16X1.5

● Gauge connection: M10X1-12.5

Product Parameters

Pressure Safety as the Main Design Feature

The supplied information identifies a 22-26 bar safety-device range.

The safety device is described as activating when pressure moves outside the specified range and releasing internal pressure to reduce the risk associated with overpressure.

For an extinguisher manufacturer, this means the safety device should not be evaluated independently. It must be considered together with:

● Cylinder design

● Filling pressure

● Temperature range

● Foam-agent configuration

● Applicable certification requirements

The actual certification test conditions should always be confirmed for the complete extinguisher.

Foam System Compatibility

The 4-9kg Powder Extinguisher Valve 1101E should be matched with the complete 4-9KG foam extinguisher configuration.

During engineering review, check:

● Cylinder neck thread

● Valve inlet

● Dip tube length

● Foam-agent filling configuration

● Discharge hose/nozzle

● Pressure gauge

● Safety-device requirements

● Applicable certification standard

The valve should not be selected based solely on the 4-9KG capacity range.

Why Valve-to-Cylinder Matching Matters

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.

Installation & Maintenance

During assembly, the 4-9kg Powder Extinguisher Valve 1101E threads should be inspected and cleaned before installation. The dip tube should be correctly positioned inside the cylinder.

For maintenance, technicians should check:

● Valve-body condition

● Corrosion

● Thread damage

● Handle operation

● Gauge connection

● Safety-device condition

● Leakage around the valve/cylinder interface

If the safety device has activated or shows abnormal deformation, the complete extinguisher should be handled according to the applicable service procedure.

OEM Customization

The 4-9kg Powder Extinguisher Valve 1101E supports customization of:

● Thread configuration

● Surface treatment

● Handle style

● Other parameters

This allows the valve to be integrated into customer-specific 4-9KG foam extinguisher assemblies.
