Apex (FMP85PSI) 85 PSI Filtamate Pressure Limiting Valve Filter Protection
Apex FMP85PSI Filtamate Pressure Limiting Valve
Pressure Protection for Filter Systems
Municipal water pressure fluctuates throughout the day, often exceeding 100 PSI during low-demand periods. These pressure surges stress membrane seals, crack filter housings, and reduce system lifespan. The FMP85PSI maintains a steady 85 PSI downstream, eliminating water hammer and extending component life. The valve also reduces flow surges that cause RO membranes to reject inconsistently, stabilizing production rates and TDS rejection.
Technical Details
| Model Number | FMP85PSI |
| Regulated Output Pressure | 85 PSI |
| Body Material | Acetyl Plastic |
| Connection Type | John Guest Speedfit Quick Connect |
| Port Sizes | 1/4" and 3/8" QC |
| Operating Temperature | 40°F – 100°F |
Application Fit
The FMP85PSI is designed specifically for reverse osmosis systems using 1/4" or 3/8" tubing with John Guest push-fit connections. It installs inline between the water supply shut-off valve and the RO pre-filter housing. Compatible with all Apex RO systems, as well as APEC, iSpring, Home Master, and other residential RO units using standard quick-connect plumbing. Also suitable for protecting inline sediment and carbon filter housings in high-pressure municipal water zones.
