Parker 100997 Pilot Assembly

The Parker 100997 is a heavy-duty, pilot-operated 1/2" assembly engineered for high-demand fluid control and refrigeration applications. Originally categorized under the Jackes Evans line and often cross-referenced as the Parker S8F Solenoid Valve (model S8F13NX00X0XS), this component is built to handle Ammonia, R-12, R-22, R-502, and other common refrigerants. It features a plated ductile iron body and handles fluid regulation in liquid, suction, and hot gas lines with a 12-ton liquid capacity and a 13mm port size. For technicians working on industrial systems, the 1/2" FPT connection and 300 PSIG MOPD rating provide the robust performance required for consistent pilot operation and refrigerant flow control.

Designed for precision, the Parker 100997 Pilot Assembly utilizes a plunger-needle setup common across the S4A, S5A, and S6N series, simplifying inventory for contractors managing multiple Parker-Refrigerating Specialties valves. Its normally-closed configuration ensures a fail-safe stop in flow when de-energized. This assembly is frequently used in HVAC pilot-operated valves and boiler spark ignition systems where reliable gas or refrigerant regulation is critical to system uptime. By leveraging a replaceable piston plug and molded Class B coil construction, this unit provides long-term field serviceability without necessitating a full valve replacement.

• Compatible with Ammonia and common refrigerants including R-22 and R-502.
• Ductile iron construction with 1/2" FPT connections for industrial HVACR durability.
• High 12-ton liquid capacity suitable for large-scale pilot-operated solenoid applications.
• Interchangeable needle assembly parts help reduce downtime during valve maintenance.
• Designed for a maximum operating pressure differential (MOPD) of 300 PSIG.

What refrigerants are compatible with the Parker 100997?
This 1/2 inch pilot assembly is designed for use with Ammonia (NH3), R-12, R-22, and R-502, making it a versatile choice for both legacy and ammonia-based refrigeration plants.

Does this assembly include the solenoid coil?
The Parker 100997 is often supplied as a pilot assembly or bare valve; the Parker 100997 solenoid coil may be required separately depending on your specific voltage requirements for the S8F series.

Can I use this for hot gas line applications?
Yes, the Parker 100997 is rated for liquid, suction, and hot gas lines, providing the high-temperature resilience needed for defrost or heat reclaim cycles.
