Multi-slotted Core Cone Spray Nozzle

Liquid flows through the nozzle's multi-slotted core, creating rotating streams. Centrifugal force forms a circular spray pattern. The core ensures uniform flow and spray, ideal for semiconductor processes, chemical distribution, cleaning, and cooling.

Full Cone Spray Nozzle Spray Pattern

Single-fluid nozzles produce a conical spray pattern, commonly referred to as full cone nozzles in the industry. The coverage shape (as seen from above after spraying onto the target) is circular.

Bell-shaped Flow Distribution

The spray volume is greatest in the middle of the spray range and gradually decreases toward the edges, forming a bell-shaped distribution curve. This makes it suitable for applications requiring concentrated impact, such as cleaning surface dirt. If uniform spraying is desired, reducing the nozzle spacing—overlapping the spray coverage of two nozzles—can improve insufficient coverage.

Multiple Flow Rates Available

The fan spray nozzle offers a wide range of flow rates. For example, at a standard design pressure of 2 Kg/cm², the flow rates range from 1 Lpm to 5.50 Lpm. (For other flow rate requirements, please refer to the specification sheet or contact us directly.)

Offers 0° to 120° Spray Angles

The solid cone nozzle offers 0° to 120° spray angles. A 0° angle provides a straight jet with a single-point spray, delivering the highest impact among all nozzle types. The 120° angle offers the widest coverage, while the standard 60° angle provides balanced impact and coverage. For specific specs, contact us.

Two-piece quick-release design

The two-piece quick-release design features three snap-lock points between the nozzle and the base, allowing for tool-free assembly and disassembly, precise positioning, and convenient maintenance.

Nozzle Tip material: PVDF
Oring material: EPDM, Viton, FEPM
Multi-slotted core center blades: PVC, PEEK (Suitable for environments below 250°C/482°F and high-corrosion chemical usage, customizable).

Installation completed.

For nozzle with QFSA Body (welding)

Step 1

Drill correspon-ding hole on your pipe.Aim the bottom of QFSA nozzle body at the hole

Step 2

Use welding torch to fix QFSA nozzle body in the pipe hole

Step 3

Aim QFH nozzle tip to nozzle body

Step 4

Put QFH nozzle tip into nozzle body.

Step 5

Fasten the tip and the body clockwise to finish the nozzle installation Finished If the neighboring nozzles stagger with each other, you should place the nozzles at least 5 degrees of declination. Otherwise, the performance might be affected.
