1. DESCRIPTION
Viking Frame Style Spray Nozzles are small, directional spray
nozzles for use on water spray systems. They are thermosensitive
glass bulb style nozzles, however they may be ordered OPEN
(glass bulb and pip cap assembly removed) for use on deluge
systems.
These Frame Style Spray Nozzles are available in various
finishes, temperature ratings, orifice sizes, and spray pattern
discharge angles to meet design requirements. When spraying,
the nozzles discharge a cone-shaped spray pattern. The deflector
determines the included angle of spray pattern discharge. A
special ring provides uniform distribution throughout the spray
pattern.
Other features include the small frame, which allows proper nozzle
positioning even in congested areas, and the nominal 3 mm glass
bulb contained entirely inside the frame for protection from most
mechanical damage. The glass bulb operating elements are
resistant to more corrosive atmospheres than metal elements.
The special PTFE coating has been investigated for installation in
corrosive atmospheres and is cULus listed as corrosion resistant
as indicated in the Approval Chart.
