Parker 4108-00 Valve

As an HVACR professional, you know that managing secondary coolants in a high-draw commercial setting requires hardware built for precision and durability. The Parker 4108-00 Valve is a normally closed solenoid valve specifically engineered to handle the unique demands of secondary coolant systems, including high-volume circulation of propylene glycol, ethylene glycol, and Dynalene. With its 1 3/8" ODF extended copper connections, this valve allows for fast brazing installation without the risk of internal heat damage, ensuring a tight seal in the suction or liquid lines of supermarket refrigeration racks.

Replacing the 22EH5C2-R1021E, this valve features a 12.2 Cv flow capacity and a hung diaphragm construction, which minimizes pressure drop and eliminates the need for a minimum pressure differential to remain open. The forged brass body and EPDM seals are chemically optimized for glycol service, maintaining a safe working pressure up to 250 PSIG. Designed for both low temperature and medium temperature applications, it stands as the industry standard for secondary loop cooling where system integrity and high flow rates are critical.

• Secondary Coolant Compatibility: Specialized EPDM diaphragm and seals compatible with ethylene glycol, propylene glycol, and other secondary fluids.
• High Flow Efficiency: A significant 12.2 Cv rating ensures minimal restriction in large-diameter 1 3/8 inch piping.
• Zero Differential Operation: The hung-pilot design allows the valve to operate reliably from 0 to 50 PSI MOPD.
• Installation Ready: Extended ODF connections streamline the brazing process for field technicians and reduce leak potential.
• Rugged Construction: Features a corrosion-resistant forged brass body with stainless steel internal components.

Is a coil included with this valve?
No, the 4108-00 is sold as the valve body only. It is compatible with Parker G23 or MKC-2 series coils, which must be ordered separately based on your specific supply voltage (24V, 120V, or 208/240V).

Can this valve be used for standard HFC refrigerants?
While the brass body is robust, the R1021E designation and EPDM seals are specifically verified for glycol and secondary coolant service. For standard refrigerants like R-410A or R-404A, a standard refrigeration solenoid with neoprene or synthetic seals is typically recommended.

What is the maximum operating pressure?
The valve is rated for a Maximum Operating Pressure Differential (MOPD) of 50 PSI, making it ideal for the lower pressure ranges found in secondary cooling loops.
