Adjustable Flow Rate Fire Nozzle (Pistol Grip)
The QLD Series is CA-FIRE's flagship adjustable flow rate fire hose nozzle — four models covering everything from 50 LPM reel-line response to 950 LPM large-flow industrial attack. Step through 4–5 flow detents and switch from straight jet to wide protective fog without leaving the line. Anodised aluminium body, DuPont™ nylon pistol grip, stainless steel spinning teeth and replaceable strainer.
One Family, Four Flow Brackets
The QLD Series adjustable flow rate fire nozzle is the everyday workhorse for municipal fire brigades and professional fire fighting teams. By rotating the flow control section, the operator changes the flow rate in 4–5 preset detents — and the same motion simultaneously transitions the spray pattern from a concentrated straight jet for direct attack to a wide fog for personnel protection, vapour mitigation and rapid heat absorption.
Four flow brackets cover every line size. The small-flow QLD6.0/4III-D (50–230 LPM, 1.2 kg) is purpose-built for high-pressure reel-line trucks and wildland response. The mid-range QLD6.0/8III-B (115–475 LPM) is the standard 1.5″/2.5″ municipal nozzle. The QLD6.0/10III-BF adds a 90° rotating rubber head that shortens operation time and reduces operator fatigue. The large-flow QLD6.0/13III-C (350–950 LPM) is designed for city fire response, petrochemical incidents and petroleum/petrochemical plant fires.
All four share the same construction core: strong lightweight anodised aluminium body, permanent laser-engraved operational markings, stainless steel spinning teeth, replaceable stainless steel strainer, rubber bumper for harsh-condition durability, and a DuPont™ nylon pistol grip. The ball valve is offered in three options — stainless steel, aluminium or brass — to match the application environment.

Built to Withstand the Fireground
Anodised Aluminium
Strong, lightweight body machined from solid aluminium billet and hard-anodised for surface hardness and corrosion resistance. Withstands cyclic impact loading and chemical exposure typical of structural firefighting environments.
Stainless Steel
The rotating tooth crown that generates the fog pattern is precision-machined stainless steel — wear-resistant against grit-laden water and dimensionally stable over the service life. The pattern stays crisp from day one to year ten.
DuPont™ Nylon
Moulded DuPont nylon handle and trigger. Engineered for impact resistance, thermal insulation against hot couplings, and grip in wet gloved hands. Replaces traditional metal grips that conduct heat and fail under drop impact.
Stainless Steel Mesh
Replaceable stainless steel strainer at the inlet filters hose debris and protects the precision-machined valve seat and orifice. Tool-free removal for in-service cleaning. Critical for hydrant-fed and reclaimed-water operations.
SS / Al / Brass Choice
Quarter-turn ball valve at the inlet — operator's choice of stainless steel (standard), aluminium (lightweight), or brass (marine and saltwater duty). Smooth on/off operation under full line pressure. Self-cleaning passage prevents debris jam.
Forged · Multi-Standard
Forged coupling rated to 7 bar working pressure. Storz, Machino, NH or NPSH thread / quick-connect available off the shelf; BS, GOST, AS and custom OEM threads available for project orders. Built-in seal eliminates field gasket failures.
QLD Series — 4 Models at a Glance
All models operate at 7 bar (≈100 PSI) working pressure. Pick by hose line size and flow requirement.
| Model | Flow Detents (LPM) | Reach | Weight | Coupling | Best For |
|---|---|---|---|---|---|
| QLD6.0/4III-D | 50 · 100 · 150 · 230 | 28 m | 1.2 kg | 1″ / 1.5″ / 2″ | Small-flow reel-line, high-pressure trucks, wildland response |
| QLD6.0/8III-BMost Popular | 115 · 230 · 360 · 475 | 34 m | 1.8 kg | 1.5″ / 2.5″ | Municipal & industrial brigades — the everyday standard |
| QLD6.0/10III-BF | 115 · 240 · 360 · 475 · 600 | 34 m | 2.13 kg | 1.5″ / 2.5″ | Crews wanting 90° rotating rubber head — easier pattern switch, less fatigue |
| QLD6.0/13III-CLarge Flow | 350 · 450 · 580 · 780 · 950 | 37 m | 2.3 kg | 1.5″ / 2.5″ | City fire response, petroleum and petrochemical plant fires |

Where Each QLD Model Earns Its Place
Structural Firefighting (Room & Contents)
The QLD6.0/8III-B at 230–360 LPM is the universal answer for a residential or small commercial structure fire. The pistol grip gives one-hand operation while the second hand manages the hose. The fog detent provides immediate gas cooling on entry; the straight jet finishes the seat of the fire.
High-Pressure Reel-Line Truck
Compact tenders and forestry trucks run a high-pressure reel line at narrow 1″ couplings. The QLD6.0/4III-D weighs 1.2 kg, opens at 50 LPM for surface cooling, and ramps to 230 LPM for active flame attack — all from a single nozzle. Compatible with 1″, 1.5″ and 2″ couplings.
Petrochemical & Plant Fires
Refinery and chemical plant fire teams need flows up to 950 LPM with a 37-metre reach to attack process-unit fires from a safe standoff. The QLD6.0/13III-C delivers that, and the wide-fog detent doubles as a heat shield for the advancing crew when paired with a curtain nozzle on a second line.
High-Rise & Compartment Fires
High-rise standpipe lines benefit from the QLD6.0/10III-BF — the 90° rotating rubber head lets the operator switch jet/fog with a single wrist motion instead of a full nozzle rotation. Reduces operator fatigue on extended interior operations and shortens decision time in narrow stairwells.
