Parker 202942 Coil

The Parker 202942 Coil is a professional-grade electrical actuator designed specifically for the Parker Refrigerating Specialties A Series valves. Engineered for 208V solenoid operation at 60Hz, this coil provides the necessary magnetic flux to actuate refrigerant flow control valves in demanding industrial and commercial environments. The Parker A8 and A9 series compatibility ensures precise pressure regulation and reliable service in ammonia or halocarbon-based systems. A veteran technician knows that a failing coil often presents as intermittent valve sticking or a complete lack of mechanical engagement; replacing with a genuine Parker Hannifin 202942 restores the valve's ability to maintain critical temperature management without compromising system integrity. This 10.5W coil features a robust, over-molded thermoplastic construction to protect internal windings from moisture and vibration—typical challenges in industrial refrigeration plant rooms. When performing a field replacement, verify your control logic voltage matches the 208V requirement to prevent overheating or failure to pull in the plunger.

Key Benefits

• Direct Compatibility: Engineered as the standard 208V replacement coil for Parker Refrigerating Specialties A8, A9, and other A-Series valves.
• Industrial Durability: Over-molded epoxy or thermoplastic enclosure provides superior protection against environmental ingress and thermal stress.
• Optimized Performance: Maintains precise magnetic circuit alignment for reliable valve opening and closing under standard operating pressures.
• Standardized Fit: Simplifies field maintenance with a design that mounts securely to existing solenoid valve stems and enclosures.

Common Questions

Does this coil include the solenoid housing or enclosure?
This part number (202942) typically refers specifically to the electrical coil. Technicians should reuse the existing metallic solenoid enclosure, as the magnetic circuit is incomplete and the coil will likely burn out if energized without being properly housed and mounted on the valve stem.

Can I use this 208V coil on a 230V or 240V circuit?
While some tolerance exists, this coil is specifically rated for 208V at 60Hz. Continuous operation at 240V may lead to excessive heat and premature winding failure. Always match the nameplate voltage of the coil to the actual measured supply voltage of your control circuit.

How do I confirm if my Parker A-series valve needs a new coil?
Check for continuity across the coil leads with a multimeter. An open circuit indicates a failed winding. Additionally, check for a magnetic pull using a solenoid tester or a screwdriver while the circuit is energized; if voltage is present but there is no magnetic field, the coil requires replacement.
