The MS Gun series are the standard applicators used in most packaging applications. The MS Guns are “air open and spring closed” and use the H-200 style gun modules. These applicators should be used with general packaging grade adhesive at temperatures from 93°C(200°F) up to 190°C(375°F).
These guns are compatible with Nordson BCS Classic Blue and Solid Blue A gun series as well as the older H-200 series. The MS Guns can be configured in various spacing configurations and have 3 available fluid ports on each gun to allow for maximum versatility when installing on the production machine.
Each MS Gun is configured with a 220-240VAC heater cartridge. The wattages vary depending on the size of each manifold. The standard heater OD is ½”.
The MS Guns come standard with a clamp for ½” round bar or hex bar stock. There are 3/8”round bar bracket clamps available and can be purchased separately. If additional brackets are required, please see the brackets section of the Valco Melton catalog.
They require compressed air at a pressure of at least 60PSI to lift the needle off of the seat which allows the adhesive to flow through the valve and onto the product. Gun configurations having 4 or more modules will require greater a higher volume of air as well as a higher pressure base no less than 80PSI. For any applicator with more than 4 modules, it’s recommended that 3/8” or 10mm air line is used to supply the compressed air. All air ports are 1/8” NPT. The MS Guns also offer various activation configurations for independent air porting. Most independent air configurations are fitted with QD fittings to allow for easy installation.
