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.
