Parker 12F23O2148A3F Solenoid Valve 2-way 3/4in Npt

Product Description

The PARKER 12F23O2148A3F is a two-way, piloted diaphragm solenoid valve designed for fluid and gas control in commercial and industrial piping systems. Configured normally open, the valve allows flow in its de-energized state and shuts off when the coil is energized. The brass body pairs with an NBR diaphragm seal for compatibility with a broad range of media. At a maximum working pressure of 125 psi and a Cv rating of 5.5, this valve handles moderate-flow applications across multiple voltage options including 12 Vdc, 24 Vdc, 24/60 Vac, 120 Vdc, 120/60 to 110/50 Vac, and 240/60 to 220/50 Vac. Weight is 2 pounds.

This valve is suited for HVAC hydronic systems, water treatment, industrial process lines, and general plumbing control circuits where a normally open two-way shutoff is required. The 3/4-inch NPT port size fits standard pipe connections common in light commercial and industrial installations. Multi-voltage coil compatibility makes it adaptable to both North American and international control circuits. The valve carries CSA, UL, and NEMA 4X ratings, supporting use in wet or washdown environments. Note that solenoid coils are not included and must be ordered separately.

Key Features

• Normally open piloted diaphragm design — opens on de-energization, closes on coil activation
• Brass body construction with NBR seal for corrosion resistance across common media
• Multi-voltage compatibility: 12 Vdc, 24 Vdc, 24/60 Vac, 120 Vdc, 120/60 to 110/50 Vac, 240/60 to 220/50 Vac
• 125 psi maximum working pressure with zero minimum operating pressure differential
• Cv rating of 5.5 supporting moderate flow capacity through 3/4-inch orifice
• NEMA 4X, CSA Certified, and UL Listed for use in demanding or wet-location environments

Compatibility

This valve is referenced under ASCO Number 8210G35 and is designed as a direct-fit two-way piloted diaphragm solenoid valve for systems requiring a 3/4-inch NPT normally open configuration.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Shut off system pressure and de-energize all control circuits before removing the existing valve or making any connections. The NPT threads require proper thread sealant per local plumbing code — do not overtighten fittings in brass-bodied valves. Verify coil voltage matches the control circuit supply before energizing, and confirm the enclosure rating meets the requirements of the installation environment per NEC guidelines.
