SG-150 Spray Systems

Hand-held Spray Guns for Coating and Masking


Dymax SG-150 hand-held spray guns, available in both standard and high flow models, provide a solution to manually spray fluids for masking and coating applications. The SG-150-RS standard-flow spray gun is ideal for dispensing fluids with viscosity lower than 10,000 cP, while the SG-150-RH is better suited for spraying fluids with viscosity of 10,000 cP and higher.

Both SG-150 models utilize a normally closed, stainless steel needle valve to control fluid flow and have a dual-acting air cylinder that provides immediate start/stop functionality. A stroke adjustment on the valve can be used to fine-tune the flow rate and a precision air regulator/gauge assembly simultaneously activates the atomizing air while the valve is opened and fluid is flowing. Both models are delivered with a round spray cap that provides a circular spray pattern, with an optional flat spray cap available if a linear or flat spray pattern is preferred.

The guns’ design incorporates a durable, lightweight, cast metal handle with pneumatic trigger mechanism so no additional electronic controls are required to activate the spray. The operator effortlessly controls the spray by manually pulling or releasing the trigger.

Dymax spray valves provide users with manual control over the valve and its spray and are ideal for the following applications:

  • Masking of turbines or other metal surfaces before surface treatment
  • Masking medical implants before finishing treatments
  • Conformal coating of circuit boards
  • Spraying solvents for cleaning part surfaces
  • Coating large parts with grease or other lubrication before assembly
