Parker 100931 Valve

The Parker 100931 is a high-performance Flo-Con A9E series commercial pressure regulator designed for precise modulation of refrigerant gas in demanding HVACR environments. This externally equalized hot gas bypass valve is engineered with a 5/8" ODF sweat connection and a 5/8" port, facilitating seamless integration into existing lines without the need for disassembly. Utilizing a pilot-operated mechanism, the Parker A9E ensures close regulation of outlet pressure at the sensing point, effectively preventing compressor short-cycling and maintaining optimal humidity levels and oil return in commercial refrigeration systems.

Built with a durable ductile iron body and brazed copper couplings, this hot gas bypass regulator is rated for a Range A pressure adjustment from 10" Hg vacuum to 120 psig. Its unique design allows for in-line cleaning and maintenance, minimizing downtime for field technicians. The Parker 100931 valve is typically applied in suction line bypass or receiver pressure control where stable pressure management is critical for system longevity and efficiency.

• In-Line Serviceability: The Parker A9E design allows for disassembly for cleaning and inspection without removing the valve body from the refrigerant line.
• Precise Pressure Control: Pilot-operated functionality provides superior accuracy in maintaining set points under varying load conditions.
• Robust Construction: Ductile iron housing and copper sweat ends ensure reliability in high-cycle hot gas bypass applications.
• Flexible Installation: Can be mounted in either vertical or horizontal orientations to suit compact commercial equipment layouts.

• How do I adjust the pressure set point? Loosen the seal nut and turn the adjusting stem clockwise to increase pressure or counter-clockwise to decrease it; for Range A, one full turn equals approximately 16 psi.
• Can this valve be field-converted to an internal equalizer? No, the Parker 100931 is an externally equalized valve and requires the replacement of the adapter to change its equalization method.
• What is the maximum rated pressure? It features a maximum rated pressure (MRP) of 400 psig (27.5 bar).
