Automatic Spray Nozzles for Intermittent Spray Applications
Intermittent spraying solutions are ideal for precision coating, lubricating, and moistening applications in Food Processing, Building Materials Manufacturing, and any other industry looking to save resources and improve product quality. Our range of air-actuated and electrically-actuated automatic nozzles offer precise dosing for a variety of spray media, including air-atomizing options for operations that require finely atomized sprays.
BENEFITS
• Precision volume sprays directly on the target
• Reduced waste and minimal overspray maintain
a clean, safe environment
• Uniform coverage
• Each nozzle is capable of a wide range of flow rates

BETE’s electric-actuated HydroPulse Spray Nozzles assure precision volumes of expensive ingredients and compounds are sprayed directly onto your processing target, with overspray waste virtually eliminated. Pair with the
BETE FlexFlow™ Precision Spray Control System to achieve uniform coverage, even if you adjust your conveyor speed. Electric HydroPulse spray nozzles do not require a compressed air source and are capable of cycling on/off up to 150 cycles per second. These features afford the option of using high-frequency cycling known as Pulse Width Modulation (PWM) to vary the liquid spray flow rate at constant supply pressure with little change in spray performance by adjusting the duty cycle. When the spray cycles at a high enough frequency, coverage uniformity is maintained because the duration between pulses of spray is short enough to ensure there are no gaps in the spray coverage.

Air Atomizing Automatic Nozzles for Precision Spray Applications
Air atomizing nozzles use the energy in compressed air or gas to produce finely atomized liquid sprays at relatively low operating pressures.
• If you have low pressure and a smaller drop size is needed that cannot be achieved with a single fluid nozzle, an air atomizing nozzle is the perfect choice.
• When a viscous fluid needs to be sprayed/atomized that cannot be sprayed with a single fluid nozzle, an air atomizing design is the best option.
The XA nozzle system has many interchangeable components that can be assembled to achieve a variety of air atomizing spraying objectives, with a choice of internal or external mix set-ups.

Design Features of the SAM Flat Fan and Narrow Round Automatic Nozzle
• Separate atomizing and fan air lines provide variable coverage and fine control of drop size without affecting liquid flow rates. Higher atomizing air pressure yields finer drop size; higher fan air pressure yields broader patterns.
• Removable plug provided for liquid recirculation port
• External mix; allows spraying of viscous materials
• Liquid flow rates are independent of air
• Precise metering of the liquid flow rate
• Pneumatically-controlled shut-off and clean-out built in
