Sporlan 100939-202940 Valve

The Sporlan 100939-202940 is a high-performance A9SE solenoid operated regulator designed for precise hot gas bypass and suction pressure control in commercial refrigeration and HVAC systems. Featuring an externally equalized design and an integrated 120V electric shut-off, this valve ensures stable evaporator pressures while preventing compressor short cycling during low-load conditions. Built with a rugged ductile iron body and 5/8" ODF copper connections, the Sporlan A9SE 5/8 is engineered for extreme durability in the field.

For service technicians, the Parker Sporlan 100939-202940 offers significant installation advantages, as the A9SE series can be brazed into the line without disassembly, maintaining the integrity of internal seals. Its pilot-operated mechanism provides tight closing and accurate modulation across a range of 10" Hg to 120 psig (Range A), making it a reliable solution for maintaining humidity control and oil return. This 5/8" ODF solenoid regulator is compatible with all major CFC, HCFC, and HFC refrigerants, ensuring versatile application across diverse hardware configurations.

• Precise Pressure Regulation: Features externally equalized technology for accurate sensing and modulation of suction pressure or hot gas flow.
• Integrated Electric Shut-Off: The 120V solenoid allows for positive system pump-down or complete circuit isolation when energized.
• Contractor-Friendly Installation: Extended 5/8" ODF sweat connections permit brazing without the risk of damaging internal components or requiring teardown.
• Heavy-Duty Construction: Built with a ductile iron body and a Class H high-temperature 120V coil for reliable operation in demanding environments.
• System Protection: Eliminates rapid compressor cycling and maintains constant evaporator temperature for improved efficiency and longevity.

Is the A9SE compatible with R-410A? Yes, the Sporlan A9 series is rated for use with most modern refrigerants, provided the system's Maximum Rated Pressure (MRP) falls within the valve's 450 psig design limit.

How do I adjust the setpoint on this regulator? To adjust the pressure, loosen the seal nut and turn the adjusting stem clockwise to raise the setpoint. For Range A, a single turn typically results in a 16 psi change.

Can I use this for liquid line service? While primarily designed for hot gas bypass and suction gas modulation, the A9SE is optimized for vapor applications. For dedicated liquid line isolation, a standard solenoid valve such as the Sporlan E or ME series may be more appropriate.
