Sporlan 930023 Valve

The Sporlan 930023 is a high-precision SDR-3X-10S electric discharge bypass valve designed for modulating refrigerant flow in complex HVACR systems. Utilizing a stepper motor drive, this valve provides superior hot gas bypass control and suction pressure regulation compared to traditional mechanical versions. Featuring 5/8" ODF solder connections, the SDR-3X integrates seamlessly into 3,000-step controllers, ensuring linear flow characteristics and tight seating. Built with a stainless steel body and hermetic construction, it manages discharge gas bypass to the evaporator or suction line to prevent coil icing and maintain compressor head pressure during low-load conditions. This electric expansion valve technology allows for tighter temperature swings and improved system stability in commercial refrigeration and precision cooling applications. Reliable and responsive, the SDR-3X-10S is an essential component for contractors optimizing system efficiency through electronic refrigerant injection and capacity control.

Key Benefits:

• Precise Modulation: Provides accurate hot gas bypass control via 3,000 discrete steps for stable suction pressure.
• Internal Durability: Engineered with a synthetic seating material for positive shut-off and long-term reliability.
• Compatibility: Designed for use with Sporlan Kelvin controllers and most third-party 42mA or bipolar stepper motor drivers.
• System Protection: Effectively manages compressor cycling and prevents evaporator freezing during partial load.
• Rugged Design: Corrosion-resistant SDR series construction suitable for demanding commercial environments.

Common Questions:
