The fluid drain valve assists
in relieving fluid

gun; triggering the gun to relieve pressure may
not be sufficient.
Pumps with Relax-A-Valve
An Evenflo air regulator may be installed
on pumps hav-
ing a Relax-A-Valve. This regulator prevents initial surg-
ing of non-atomized fluid when the gun is triggered. Air
pressure in the pump is relieved automatically each time
the gun trigger is released. When used with
a
Relax-A-
Valve set
in the automatic position, fluid pressure is
relieved automatically also.
