York S1-903406 Valve
The York S1-903406 Valve is a critical discharge bypass component designed to maintain precise suction pressure during low-load conditions. As a direct equivalent to the Sporlan ADRSE-2-0/80, this 4 ODF pressure regulating valve features an external equalizer and a solenoid stop feature, making it indispensable for preventing evaporator coil freeze-up and short-cycling in commercial HVACR systems. With an adjustment range of 0/80 psi, this refrigeration bypass valve allows technicians to fine-tune system response to varying thermal loads, ensuring consistent compressor return gas temperature and oil return. The ODF solder connections provide a leak-proof, high-integrity joint suitable for high-pressure refrigerants common in York and Johnson Controls equipment. When you are troubleshooting capacity control issues or looking for an ADRSE-2-0/80 replacement, this OEM-spec discharge bypass valve offers the exact flow characteristics and mechanical reliability required to keep industrial chillers and split systems within design parameters.
Key Benefits:- Precise Pressure Regulation: Maintains stable suction pressure between 0 to 80 psi to protect against low-load evaporator icing.
- OEM Compatibility: Specifically engineered as the primary York S1-903406 service part, ensuring a perfect drop-in fit for existing piping.
- Integrated Solenoid Feature: The "S" designation indicates a solenoid stop capability, allowing for positive shut-off during pump-down or off-cycles.
- Superior Build Quality: High-grade brass body and 4 ODF (1/2" ODF) connections provide the durability needed for the rigorous environment of a mechanical room.
Is the S1-903406 interchangeable with the Sporlan ADRSE-2?
Yes, this part is identical to the Sporlan ADRSE-2-0/80. It follows the same technical specifications for pressure range, port sizing, and connection type.
What is the purpose of the external equalizer on this valve?
The external equalizer allows the valve to sense the actual pressure at the evaporator outlet, compensating for any pressure drop across the distributor or evaporator coil for more accurate modulation.
When should I replace a discharge bypass valve?
Replace the valve if you notice the system failing to maintain minimum suction pressure, evidence of refrigerant migration during the off-cycle, or mechanical sticking that leads to erratic compressor behavior.
