Hydronamic (CV18S-MxM) Check Valve - 1/8" MNPT x 1/8" MNPT
1/8" MNPT Check Valve
Precision-engineered stainless steel check valve prevents backflow in compact water treatment systems
The Hydronamic CV18S-MxM check valve uses 303 stainless steel construction to prevent reverse flow in pressurized water lines. The 1/8" male NPT connections on both ends fit directly into compact filtration assemblies, permeate lines, and booster pump installations where space is limited.
Technical Details
| Material | 303 Stainless Steel |
| Connection Type | 1/8" MNPT x 1/8" MNPT |
| Cracking Pressure | 1.0 psi ± 0.5 |
| O-Ring Compounds | Silicone, Buna, Viton, EPDM |
| Flow @ 5 psi | 0.35 GPM |
| Flow @ 10 psi | 0.64 GPM |
| Flow @ 15 psi | 0.73 GPM |
| Flow @ 20 psi | 0.84 GPM |
Where It Fits
The CV18S-MxM works in any 1/8" NPT threaded port on RO systems, UV housings, booster pumps, storage tanks, or pressure gauges. Common installations include permeate lines to prevent drain backflow, pump discharge ports, and atmospheric tank vents. The low 1.0 psi cracking pressure minimizes restriction in low-flow applications while still providing reliable one-way flow control.
