Parker 12F24C2148AAF 2-way Solenoid Valve 3/4 in Npt

Product Description

The PARKER 12F24C2148AAF is a two-way, normally closed, piloted diaphragm solenoid valve rated for 250 psi maximum working pressure. It features a brass body with an NBR seal and a 3/4-inch NPT port, making it well suited for controlling fluids, gases, and light oils in industrial and commercial HVAC, plumbing, and process systems. The valve carries a Cv rating of 6.5 and accepts a wide range of voltages including 12Vdc, 24Vdc, 24/60Vac, 120Vdc, 120/60 to 110/50Vac, and 240/60 to 220/50Vac. A licensed technician or pipefitter typically handles installation in systems requiring reliable on/off flow control.

This valve is designed for residential and commercial applications involving water, air, gases, and light oils. Its piloted diaphragm design requires a minimum operating pressure differential of 5 psi to actuate, which is standard for this valve type. The 3/4-inch NPT threaded port fits common pipe sizes found in HVAC hydronic systems, irrigation controls, compressed air lines, and light industrial fluid circuits. The brass body resists corrosion in wet service environments, and the NBR seal handles a broad range of compatible media.

Key Features

• Two-way, normally closed piloted diaphragm design for reliable on/off flow control
• Brass body construction for corrosion resistance in fluid and gas service
• NBR seal material compatible with water, air, gases, and light oils
• Multi-voltage coil compatibility: 12Vdc, 24Vdc, 24/60Vac, 120Vdc, 120/60 to 110/50Vac, 240/60 to 220/50Vac
• 250 psi maximum working pressure with a Cv rating of 6.5
• CSA Certified, UL Listed, and NEMA 4X rated for demanding installation environments

Compatibility

Designed for use with fluids, gases, and light oils in systems requiring 3/4-inch NPT two-way normally closed solenoid valve control. ASCO cross-reference number 8210G3. Note: solenoid coils are not included and must be ordered separately based on the required operating voltage.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or HVAC technician in accordance with applicable local codes and IFGC or IPC guidelines where relevant. Shut off and relieve pressure from the system before removing any existing valve or fitting. Confirm the minimum 5 psi operating pressure differential is available in the system before commissioning, as the piloted diaphragm design requires it to open. Verify coil voltage matches the control circuit before energizing.
