Description
CAUTION: This gun is intended for use only with the following DuraBlue units:
D4L, D10L, D16L, D10 and D16. Do not use this gun with any other type of
melter.
B900-N and B900SW-N (B900) electric guns are high-speed, all-electric guns designed for
the precision placement of hot melt adhesive. The module is an electric solenoid valve
with a spring-loaded armature inside the adhesive chamber. The module stroke can be
adjusted to change and to balance the adhesive flow between modules. The module coil is
AC-powered.
The gun temperature is controlled by a resistance temperature detector (RTD). RTD
overtemperature protection is provided by a 246 _C (475 _F) overtemperature
thermoswitch.
