Multi-slotted core design

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 shape, known as solid cone nozzles, resulting in a circular pattern.

Mountain-Shaped Flow Distribution

The Full Cone Spray Nozzle has maximum spray volume in the center, decreasing towards the edges, forming a mound-shaped distribution. Ideal for concentrated impact applications like surface cleaning. For uniform spraying, install nozzles closer together to overlap coverage areas and improve uniformity.distribution.

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 2.5 Lpm to 5.5 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.

Quick-release design, snap-lock positioning, prevents water leakage

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.

Installation

For nozzle with QS Body (thread)

Step 1

Drill correspon-ding female threads on your pipe

Step 2

Aim the thread of nozzle body at the female thread. Tightening the body clockwise at the pipe hole.

Step 3

Aim QSH nozzle tip to nozzle body.

Step 4

Put QSH 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. 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.
