Parker 20F24C2172AAF Valve

The Parker 20F24C2172AAF is a heavy-duty, 2-way normally closed solenoid valve designed for high-flow industrial fluid control. Built with a rugged forged brass body and a 1-1/4" NPT connection, this pilot-operated diaphragm valve is engineered to handle demanding media, including air, water, and light oils. With a flow coefficient (Cv) of 15 and an 1-1/8" orifice, it provides the high-capacity throughput required in irrigation, fire suppression, and large-scale industrial washing systems. This Gold Ring Series unit utilizes NBR seals, supporting media temperatures up to 180°F. Note that this is a pressure vessel only part and requires a compatible Parker solenoid coil (typically 6W AC Class F) for electrification. It maintains a reliable seal under pressures up to 125 PSI for water and 150 PSI for air, requiring a minimum differential of 5 PSI for proper diaphragm actuation. For veteran contractors, the offset pilot design ensures consistent performance and simplified field maintenance in HVACR and process control environments.

• High Flow Capacity: A Cv of 15 ensures minimal pressure drop across 1.25-inch piping systems.
• Industrial Durability: Forged brass construction provides a high burst strength and long-term corrosion resistance.
• Standardized Compatibility: Part of the Gold Ring Series, making it easy to pair with a wide range of standard Parker coils and repair kits.
• Reliable NC Operation: Naturally failsafe in the closed position, preventing unauthorized fluid flow during power loss.

• Does this valve include the solenoid coil? No, the 20F24C2172AAF is the pressure vessel assembly; the electrical coil must be purchased separately based on your specific voltage requirements.
• What is the minimum pressure required? This is a pilot-operated valve and requires at least a 5 PSI pressure differential to open the diaphragm.
• Can this be used with steam? This model is rated for water, air, and light oil up to 180°F; it is not recommended for high-pressure steam applications.
