Parker 20F24C2172A3F 2-way Solenoid Valve 1-1/4 in Npt

Product Description

The PARKER 20F24C2172A3F is a two-way, piloted diaphragm solenoid valve designed for fluid control in industrial and commercial systems. It features a 1-1/4 inch NPT port, a brass body, and an NBR seal, making it suitable for water, air, and compatible fluid service. The valve is normally closed and opens when the coil is energized. It accepts multiple voltage inputs including 12Vdc, 24Vdc, 24/60Vac, 120Vdc, 120/60 to 110/50Vac, and 240/60 to 220/50Vac, giving it broad application across different control circuits. Maximum working pressure is 125 psi, and the Cv factor is 15.0, indicating strong flow capacity for its port size.

This valve is suited for HVAC, plumbing, irrigation, and light industrial fluid control applications where a normally closed, electrically actuated shutoff is required. Its piloted diaphragm design requires a minimum operating pressure differential of 5 psi to function correctly, which is standard for this valve type. Installation is typically performed by licensed HVAC technicians, plumbers, or industrial maintenance personnel. The multi-voltage coil compatibility makes it adaptable to both AC and DC control systems commonly found in commercial building automation and process control.

Key Features

• Two-way normally closed piloted diaphragm design opens on coil energization
• 1-1/4 inch NPT port with 1-1/8 inch orifice for high flow capacity (Cv 15.0)
• Brass body and NBR seal for compatibility with water and common process fluids
• Multi-voltage coil options: 12Vdc, 24Vdc, 24/60Vac, 120Vdc, 120/60 to 110/50Vac, 240/60 to 220/50Vac
• CSA Certified, UL Listed, and NEMA 4X rated enclosure for wet or washdown environments
• Maximum working pressure 125 psi; rated to 150 degrees F

Compatibility

This valve corresponds to ASCO Number 8210G8. Designed as an OEM-style replacement or new-installation two-way piloted diaphragm solenoid valve for systems requiring a 1-1/4 inch NPT normally closed valve with multi-voltage coil compatibility. Note that solenoid coils are not included and must be ordered separately.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial technician. Shut off fluid supply and de-energize the control circuit before removing or installing the valve. Confirm minimum operating pressure differential of 5 psi is available in the system, as piloted diaphragm valves require line pressure to open fully. Coils are not included with this valve body and must be sourced and matched to the control voltage before commissioning.
