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 flat-faced flanges to match ANSI 150 lb flanges of the same nominal size. Clearly marked on the proportioner body is the flow direction arrow, as well as the type and percentage of the designated concentrate.
The inlet nozzle is secured by a stainless steel retaining ring that is internally concealed to prevent removal after installation.
The metering orifice is sized according to the type and percentage of concentrate used and is also secured with a stainless steel retaining ring.
Application
CHEMGUARD proportioners are specifically designed to accurately proportion and control the mixing of pressurized CHEMGUARD foam concentrates into a water stream with minimum pressure loss. CHEMGUARD proportioners are UL Listed and FM Approved with various CHEMGUARD foam concentrates and they are used in conjunction with bladder tanks. Typical applications include flammable liquid storage tanks, loading racks, aircraft hangars, heliports, and anywhere flammable liquids are used, stored, processed, or transported.
