The Crispin
Company Air Valves
Sewer Air Valves
- Both
Air and Vacuum and
Pressure Sewer valves
are available. With its long body and float near the bottom, the
effluent entering the valve remains low and away from working parts.
Deep Well Air
Valves -
Deep Well Air Valves
have an adjustable top which controls the velocity of air discharged
from the valve. This causes a pressure loading on the rising column
of water which reduces shock at the check valves. Maintenance is
thereby reduced.
Slip Joints
-
Slip Joints are
adjustable cast iron units which are installed on a piping system
between a meter, fixture, gauge, etc. and the pipe. The fitting can
be removed without the necessity of breaking a joint or removing a
section of pipe.
Negative
Pressure Valves -
Negative pressure valves
are used to vent accumulated air from the high point of a siphon. |
