Parker 12FS5C2448ACF Solenoid Valve 3/4 Inch Npt

Product Description

The PARKER 12FS5C2448ACF is a direct-acting, normally closed solenoid valve designed for controlling flow in hot water and steam systems. Built with a brass body and a polytetrafluoroethylene (PTFE) seal, this valve handles demanding temperatures up to 320 degrees F and working pressures up to 80 psi. The 3/4-inch NPT port and a Cv factor of 7.4 make it well-suited for moderate-to-high flow applications. It accepts a wide range of voltage inputs including 12 VDC, 24 VDC, 120 VDC, 24/60 VAC, 120/60 to 110/50 VAC, and 240/60 to 220/50 VAC, providing flexibility across different control systems. Licensed plumbers and HVAC technicians are the primary installers of this valve.

This solenoid valve is used in residential and commercial plumbing and HVAC systems where automated on/off control of hot water or steam is required. Typical applications include boiler feed lines, steam distribution, and hydronic heating circuits. The normally closed design ensures the valve defaults to a closed position when de-energized, which is the preferred fail-safe state in many hot water and steam control scenarios. Its multi-voltage compatibility makes it adaptable to a wide variety of control panel configurations without requiring a dedicated coil for each voltage.

Key Features

• Direct-acting, normally closed operation for reliable fail-safe shutoff
• Brass body construction rated for hot water and steam service up to 320 degrees F
• PTFE seal material for chemical resistance and high-temperature durability
• 3/4-inch NPT port with a Cv factor of 7.4 for strong flow capacity
• Multi-voltage coil compatibility: 12 VDC, 24 VDC, 120 VDC, 24/60 VAC, 120/60 to 110/50 VAC, 240/60 to 220/50 VAC
• CSA Certified, UL Listed, and NEMA 4X rated for use in wet or washdown environments

Compatibility

Designed for hot water and steam control applications. Note that solenoid coils are not included with this valve body; the appropriate coil must be selected and ordered separately to match the desired operating voltage.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes and the International Plumbing Code (IPC). Shut off system pressure and allow the line to cool before beginning any valve replacement or installation work. Verify coil voltage matches the control circuit before energizing. Apply thread sealant appropriate for steam and hot water service to all NPT connections before assembly.
