Specializing in Air Release, Check, Butterfly & Plug Valves; our products are used in almost every application where water or liquid is moved from one place to another — from pipeworks in the municipal water industry to a wide range of applications across a variety of markets.
We look forward to putting over a century of experience to work on your next valve project.
Air Release Valves Clean Water
Air & Vacuum valves are designed to vent large quantities of air when filling pipelines, and to allow air to re-enter pipelines when draining to prevent vacuum collapse.
C Series Combination Air Valves
Combination Air Valves consist of Air and Vacuum Valves and a Pressure Valve mounted in a single body, providing the integrity of a single body casting while permitting each valve of the combination to operate as a separate unit.
M Series Midget Air Release Valves
Midget Air Valves are used on hot and cold water systems, including irrigation systems where the venting of small accumulations of air is required while the system is in service and under pressure.
PL Series Pressure Air Release Valves
Pressure Air Release Valves are used for the venting of accumulating air while the system is in service and pressurized.
AR Series LV Air Release Valve
The Crispin Low Capacity Pressure Air Release Valve continuously and automatically vents accumulations of air under pressure.
UL Series Universal Air Release Valve
Crispin Universal Air Release Valves perform the function of both Air & Vacuum and Pressure Air Valves, permitting the application of various pressure orifice sizes for a range of air volume requirements under varying pressures. The design saves space and reduces cost.
Air Release Valves Sewage
S Series Air:Vacuum Sewer Valves
Crispin Air & Vacuum Sewer Valves have a long body with a float near the bottom. The waste-containing solid remains low and away from working parts, venting the pipe line when filling, and permitting air to re-enter to relieve the vacuum.
S & US Series Sewage Air Valves
Pressure Air Release Valves have a long body to keep liquid waste and solids away from working parts. These valves vent accumulations of air and gas while the system is in operation and under pressure.
Globe Silent Check Valve
Globe Silent Check Valve Mounted vertically or horizontally, these valves are designed to close before the pump stops, preventing flow reversal, and eliminating water hammer and system surges.
RF Series Rubber Flapper CV
A versatile and cost-effective solution, the Rubber Flapper Check valve provides a smaller stroke than conventional swing check valves, reducing slamming while offering a strong, quick seal.
Wafer Style Silent Check Valve
Wafer style Silent Check Valves have the same operating principle as the Globe Check valve, but they are offered in a configuration that allows placement between two flanges.
