Deep Well Air Valves
with stainless steel trim or bronze and stainless steel float
The Crispin Deep Well Air Valve is designed to
vent air from the pump column at the discharge point ahead of the check or control valve.
The air flow is controlled by screwing down the plunger on the deep well top to a point
where the float ceases to flutter. In the event of excessive water spillage or slamming of
the float into its seat, further adjustment may be necessary. After the correct setting
has been found, the jam nut is tightened.

*All Crispin Vlaves are designed for a
cold water working pressure of 300 PSIG
Crispin Valve provides the same unique
design in the deep well valve as in the air and vacuum valve. That is, the float is
peripherally guided to the seat whihc permits the float to self center and tightly seal
the orifice.
