Home > Corp Stops

Corporation Stops
with Injection Quills are used for injecting chemicals delivered by metering pumps or ejectors into mains, tanks, cooling towers and process water systems. The diffuser in the corp stop extends approximately a third of the way into the water stream allowing for a more uniformed dispersion of chemicals.


The use of a corporation stop valve is needed when the process water pipe cannot be drained at the diffuser to allow for maintenance and / or cleaning.
