Description
High-pressure needle spray nozzle is a high-performance linear needle nozzle, which is precisely machined to ensure the continuity of flow and straight line and can be matched with various spray bars. High-pressure needle spray nozzles are also called papermaking nozzles and edge-cutting water needle nozzles.
Feature and Application
The high-pressure needle nozzle is that it has been adopted by the majority of paper mills in China due to the stable injection, and the design can effectively prevent the occurrence of clogging.
Its main uses are high-pressure swing cleaning of the wire section, high-pressure swing cleaning of the press section felt, blind hole roller cleaning, grooved roller cleaning, and high-impact cleaning. It is your smart choice for cleaning felts, textiles, and vacuum rolls. It can be used with the reciprocating swing spray bar and can be interchanged with other water needle nozzles.
It can also be used for paper edge cutting. It has many characteristics such as accurate and clean edge cutting. It can form a straight needle-shaped liquid column flow under different pressure conditions and can withstand pressures up to 140 bar. The nozzle material is ceramic and ruby.
In order to meet different wear resistance requirements, our company can provide all stainless steel nozzles and body stainless steel, inlaid with ceramic cores to improve the wear resistance rate of the product and prolong the service life of the nozzle.

How to Select High-Pressure Needle Spray Nozzle
high-pressure needle spray nozzle forms a concentrated liquid jet for localized impact rather than broad-area coverage. This page should be evaluated as an engineered component: final performance depends on the liquid, pressure at the nozzle, installed geometry and the selected configuration.
Technical selection criteria
- Process fluid: identify composition, temperature, specific gravity, viscosity, suspended solids and any corrosion or erosion risk.
- Required duty: state flow per nozzle, minimum and maximum inlet pressure, operating cycle and acceptable turndown.
- Spray result: define pattern, angle, coverage width or diameter, stand-off distance, droplet requirement and allowable overspray.
- Installation: confirm thread standard, connection size, orientation, header spacing, available clearance and access for inspection.
- Materials and maintenance: match body, insert, seals and accessories to the fluid and environment; include filtration and cleaning requirements.
Where this nozzle type fits
Typical evaluation areas include precision cleaning, edge trimming, descaling and targeted wash-down where a coherent jet is required. When comparing high-pressure needle spray nozzle with solid stream nozzle, needle jet nozzle, high-impact cleaning nozzle, select the pattern and construction that solve the actual process duty. A wider angle does not automatically mean better atomization, and a higher pressure does not automatically deliver the best coverage.
Engineering limits and installation checks
Published flow and spray data are normally based on defined test liquids and conditions. Viscosity, specific gravity, pressure loss, solids, temperature, nozzle wear, pulsation and nearby airflow can change field performance. Confirm the installed pressure at the nozzle—not only pump discharge pressure—and verify overlap or target coverage before finalizing a production header.
Information to include with an RFQ
Provide liquid properties, target flow, pressure range, spray angle or coverage, distance to target, material, connection, quantity, duty cycle and installation drawings. Jeltecn can use these inputs to compare the requested configuration with related spray nozzle application guidance and the complete industrial spray nozzle range.
Frequently asked questions
What determines the flow of high-pressure needle spray nozzle?
Flow depends primarily on the selected orifice and pressure differential, then must be corrected for liquid density, viscosity and the actual piping losses.
How should this nozzle be validated before production use?
Confirm the exact model and material, review the performance table, test coverage under representative conditions and document inspection or replacement criteria.
