Mazzei (SPSA-1.5-A) Suction Port Screen w- Check Valve - 1.5" FNPT Connection
Mazzei SPSA-1.5-A Suction Port Screen Assembly with Check Valve
The Mazzei SPSA-1.5-A is a dual-function component that screens particulate from chemical feed lines while preventing reverse flow when the injector shuts down. This assembly threads directly onto the suction port of compatible 1.5-inch Mazzei injectors, eliminating the need for separate screen and check valve installations.
SPSA-1.5-A Component Details
| Model Number | SPSA-1.5-A |
| Connection Type | 1.5" FNPT (Female National Pipe Thread) |
| Screen Function | Filters particulate from chemical feed |
| Check Valve Function | Prevents backflow when injector stops |
| Material | Chemical-resistant polymer construction |
| Manufacturer | Mazzei Injector Corporation |
Injector Fitment
The SPSA-1.5-A is designed for use with Mazzei injectors featuring 1.5-inch suction ports. This includes select models in the Mazzei 1.5-inch chemical and air injector series. Verify your injector model's suction port threading before ordering. The assembly installs hand-tight with optional wrench flats, and should be oriented with check valve flow direction matching the injector's draw direction. Suitable for agricultural fertigation systems, municipal water treatment, aquaculture, and industrial chemical dosing applications where debris protection and backflow prevention are required.
