Data Sheet Anti-Drip Spray Nozzles Type 4023 Application Many nozzles are satisfactory for spraying liquids, but for a positive cut-off ask for the Hago type 4023 nozzle. Our exclusive design produces a precisely controlled flow rate and spray angle and includes a liquid cut-off near the orifice. Fluid cut-off near the orifice can be very important in situations where excessive after drip can damage or destroy things located beneath the nozzle. Chemicals, insecticides, and even plain water, if allowed to drip, can foul the environment or injure livestock, seedlings and industrial materials. With the type 4023 anti-drip nozzles, operators can achieve fluid cut-off near the orifice while maintaining pressure within the nozzle supply system. The type 4023 nozzle emits a finely atomized spray mist suitable for nearly all humidifying, light wetting and evaporative cooling application. This nozzle has become a nozzle of choice for the insect spray system industry.
