Parker RK4001 Repair Kit

The Parker RK4001 Repair Kit is a comprehensive diagnostic and overhaul solution for Type R and Type S solenoid valves. Engineered for field service professionals, this kit replaces internal components compromised by debris or normal mechanical wear. It features a high-grade solenoid valve piston assembly, stainless steel spring, and precision-molded synthetic seating materials to ensure a bubble-tight shut-off. The RK4001 is compatible with a wide range of common HCFC and HFC refrigerants, including R-22, R-134a, and R-404A. By restoring the valve's pilot-operated functionality, technicians can eliminate solenoid valve leaking and chatter without the need for a full valve body replacement. This kit is essential for maintaining system pressure differentials and securing optimal flow control in commercial refrigeration systems. Using genuine Parker Sporlan replacement parts ensures that the valve retains its original factory performance ratings and pressure thresholds during high-demand cooling cycles.

• Full Internal Overhaul: Includes all necessary pistons, springs, and gaskets to restore Parker solenoid valves to factory specifications.
• Enhanced Durability: Constructed with materials resistant to common system contaminants and synthetic oils.
• Field Serviceable: Designed for rapid installation to minimize system downtime and labor costs during HVAC repair.
• Universal Refrigerant Compatibility: Suitable for modern high-pressure systems and legacy refrigerant applications.

Is this kit compatible with both normally open and normally closed valves?
The Parker RK4001 is specifically designed for the internal components of normally closed Type R and S valves; always verify your valve model prefix before installation.

Does this kit include the solenoid coil?
No, this is a mechanical repair kit for the internal piston and seat assembly. If the coil is burnt out, it must be purchased separately based on the required voltage.

Can I use this for liquid line and suction line applications?
Yes, provided the valve body is a matched Type R or S, this kit handles the mechanical requirements for both liquid and suction service.
