G20 - Automatic Spray Nozzles, Accessories

Features and Benefits

51120 heat jacket:
- Keeps viscous fluids warm as they pass through air atomizing nozzles thus reducing clogging.
- Provides uniform temperature control.
- Easy installation by slipping over the nozzle and stays connected to heat source while the nozzle is removed for service.
- Versions for VAU, VMAU, JAU and JJAU air atomizing nozzles.
Solenoid valves:
- Designed for automatically operated systems requiring on/off flow.
- Solenoid valves are normally closed and provide dependable service in both air and liquid lines within 40°F to 165°F (5°C to 75°C).
- 10 watt class “F” coils for continuous duty and UL/CSA approved. Ambient operating temperatures range from 15°F to 122°F (–10°C to 50°C). Coils rated for dual frequency operation suitable for international use. Coil is encapsulated in a molding compound to resist high humidity and fungus growth.
- Enclosure can be rotated 360° and includes a 1/2" NPT connection.
- Solenoid valve bodies are available in stainless steel or brass.
- For high velocity flow, a stainless steel pilot orifice helps eliminate premature leaking and increases service life. Kel-F® or Viton® seals are molded into stainless steel floating bottom plungers.
- Floating plungers automatically compensate for vibration, shock, wear and deformation providing a bubble-tight seal. Buna-N material is used with diaphragm valves.
- The solenoid valves can be mounted in any position and are direct pipe mounted.
- Additional bottom mounting is provided on 11438-20, -21 and -22 by two 10-24 tapped holes.
- The valve action within these models is diaphragm, pilot-operated diaphragm or direct acting poppet.
38680 quick exhaust valve:
- Quick exhaust valve increases line exhaust to a full 1/4" port (Cv = 1.0).
- Air-actuated spray nozzles are quickly shut off without spitting, especially when the solenoid valve is mounted more than 3' (1 m) from the spray gun.
Electric band heater:
- Ensures easy and economical spraying of atomized viscous liquids.
- Trouble-free atomization of hard-to-spray liquids such as wax, adhesives, starches and syrups ensures product and process quality and minimizes maintenance time caused by nozzle clogging.
- Easily slips over the body of a VMAU variable automatic spray nozzle.
- Heat is efficiently transferred to the band heater in seconds.
- Even heating of the nozzle inlets, body and air cap assures a consistent liquid temperature and achieves optimal spray performance.
- Easy removal and disassembly for cleaning saves on maintenance time – especially important when used in dirty environments.
- Maximum operating temperature: 250°F (121°C).
- Fiberglass reinforced silicone rubber heat band.
- Silicone insulated lead wires.
- Suitable for use with all VMAU variable automatic nozzles in stand-alone and manifold configurations.
