Maintain peak operational efficiency in your industrial refrigeration systems with the Parker 202066 Repair Kit. Specifically designed for the Parker Refrigerating Specialties S4A solenoid valve with a 1 1/4 inch port size, this comprehensive rebuild package contains all critical internal components required to restore factory-spec performance. The kit includes the S4A main valve plug kit (202039), the piston kit (200767), and the S6 plunger/seat kit (201630). By servicing the pilot operated mechanism with genuine solenoid replacement parts, technicians can effectively eliminate issues like internal leakage and sluggish actuation caused by mineral deposits or spring fatigue. This heavy-duty kit is compatible with systems utilizing ammonia, R-22, R-502, and other common refrigerants. Utilizing these refrigeration valve components ensures the integrity of the PTFE seat material and maintains the 400 PSIG design pressure vital for high-demand HVACR valve maintenance.

• OEM Compatibility: Exact fit for 1 1/4" S4A series solenoid valves to ensure seamless integration.
• Performance Restoration: Includes the 200767 piston and 201630 plunger kits to resolve sticking or failure to close.
• Versatile Media Support: Suitable for ammonia (NH3) and fluorinated refrigerant liquid or suction lines.
• Durable Construction: Features high-grade materials like PTFE and stainless steel to resist wear in high-cycle applications.
• Cost-Effective Maintenance: Rebuilds the internal pilot and main seat assembly without requiring full valve body replacement.

What symptoms indicate the S4A needs a 202066 repair kit?
Technicians typically look for a valve that fails to open under pressure, exhibits a chattering noise when energized, or allows refrigerant bypass when the coil is de-energized. These issues often stem from a worn main valve plug or a sticking plunger assembly contained within this kit.

Can this kit be used for ammonia service?
Yes, the components in the Parker 202066 kit are specifically designed to be compatible with ammonia, provided they are installed in a valve body with appropriate flanged or socket weld connections.

Does this kit include the solenoid coil or housing?
No, this is an internal repair kit only. It includes the plunger, piston, and seat components. If you have a electrical failure, the coil must be sourced separately.
