Each CHEMGUARD proportioner consists of a body, inlet nozzle, and metering orifice, all of which are corrosion-resistant brass.
The proportioner body is designed with a female NPT threaded inlet and a male NPT threaded outlet in sizes of 2 in. or 2 1/2 in. Clearly marked on the proportioner body is the flow direction arrow, and the type and percentage of concentrate that it was designed to proportion.
The inlet nozzle is secured by a stainless steel retaining ring.
The metering orifice is sized according to the type and percentage of concentrate used, and the orifice is also secured with a stainless steel retaining ring.
