Double injector ST-164 from R+M / Suttner
The ST-164 double injector is made of stainless steel and special high-performance plastics. The switch lever determines the dosing of one of two connected chemicals. In its possible configurations, it is suitable for metering at low pressure from approx. 5 bar to max. 350 bar. In the flushing position, up to 60 l/min. can pass through the injector unit with virtually no pressure loss.
In combination with a foam lance (ST-72, ST-74 or ST-75) or a surge control or multi-directional nozzle, the ST-164 can be used to draw in chemicals via the integrated stainless steel non-return valves and, depending on the nozzle selected, spray and foam them up.
This injector has an optional compressed air connection to supply the amount of air required for foaming already in the injector unit. A foam lance that does not suck in air itself is essential for applying the foam.
Furthermore, this double injector is suitable for low or medium pressure from 5 bar water inlet pressure and produces an excellent foam pattern with the appropriate compressed air supply.
The ST-164 injector is available in nozzle sizes 1.2 to 2.8 mm. The scope of delivery includes 10 dosing nozzle inserts for fixed dosing settings. The chemical connection is equipped with an integrated non-return valve.
