Parker 4266-00 Valve

The Parker 4266-00 Valve is a high-performance normally closed solenoid valve engineered for precision refrigerant flow control in commercial HVACR systems. Specifically designated as the R26E63M model, this valve features 3/8" ODF solder connections, ensuring a leak-proof integration into the liquid or suction line. It serves as the direct R20E83 replacement valve, though technicians must note that transitioning to this updated series requires a new solenoid coil. When retrofitting, always verify the system voltage to select the appropriate coil for the 4266-00 assembly. Built for durability in high-pressure environments, this Parker Sporlan solenoid valve provides the reliable shut-off capability necessary for modern refrigerant flow control applications. Its robust internal construction is optimized for longevity and compatibility with standard synthetic oils and various refrigerants, making it a staple for contractors maintaining older systems requiring specific legacy part migrations.

• Direct Drop-in Compatibility: Engineered specifically to replace the R20E83, reducing field modification time.
• Superior Seal Integrity: The 3/8" ODF extended copper tails allow for easy brazing while protecting internal components from heat damage.
• High Pressure Rating: Designed to handle the rigorous demands of commercial refrigeration cycles without pilot-seat failure.
• Normally Closed Logic: Ensures positive shut-off during power loss or system standby to prevent liquid migration.
• Field Serviceable: The design allows for straightforward coil replacement and internal cleaning without removing the valve body from the line.

Can I reuse my existing coil when replacing an R20E83 with a 4266-00?
No, the 4266-00 requires a new coil compatible with the updated stem design. Always check your existing voltage before ordering the replacement coil.

What is the orientation requirement for the R26E63M valve?
The valve must be installed in a horizontal line with the coil in an upright position (within 45 degrees of vertical) to ensure proper plunger operation and drainage.

Is this valve compatible with high-pressure refrigerants?
Yes, the 4266-00 is rated for modern refrigerants, though you should always verify the Maximum Rated Pressure (MRP) against your specific system requirements.
