Parker 04F20C2318BDF Valve

The Parker 04F20C2318BDF Valve is a direct acting 2-way solenoid valve engineered for demanding hydronic and commercial boiler applications. This Normally Closed (N/C) unit features a 1/4" NPT port size and is built with a rugged forged brass body to ensure durability in high-cycle environments. Part of the Parker Gold Ring Series, it is specifically configured for hot water service, utilizing high-grade EPDM seals capable of managing fluid temperatures up to 185°F. With a 9/32" orifice and a 0.8 to 1.1 Cv flow coefficient, it provides precise flow regulation without the need for a minimum pressure differential to operate. This 24VAC solenoid valve is rated for a 90 PSI maximum operating pressure differential (MOPD), making it a reliable choice for HVAC contractors looking for an OEM replacement valve that meets NEMA 4X standards for environmental protection.

• Direct Acting Design: Operates reliably from zero pressure up to its maximum rating, eliminating the need for pilot pressure in low-flow systems.
• High-Temperature Resilience: The EPDM rubber seals and Class 155 (Class F) coil insulation are optimized for hot water applications.
• Environmental Protection: Encapsulated coil design allows for installation in damp or demanding locations, meeting NEMA 4 and 4X requirements.
• Fast Response Time: Provides instantaneous shut-off and opening, critical for maintainng tight control loops in HVACR systems.
• Interchangeable Coils: Compatible with Parker Gold Ring unit valves, allowing for easy field upgrades or voltage conversions if necessary.

Is this valve suitable for steam applications?
While designed for hot water at 90 PSI, this specific Parker 04F20C2318BDF model is optimized for liquid service. For high-pressure steam, always verify the seal material and pressure ratings against the specific steam schedule of the system.

Can I install this valve in any orientation?
For best performance and to prevent debris accumulation in the core tube, it is recommended to install the valve with the solenoid in a vertical, upright position. However, it can function in other orientations if space constraints require it.

What is the purpose of the manual override on this series?
This specific model usually does not include a manual override; the Normally Closed function ensures the valve returns to the closed position immediately upon loss of 24V power for system safety.
