Sporlan 903322P Valve
The Sporlan 903322P is a high-performance ADRSE-2 discharge bypass valve designed for precise compressor capacity control in commercial refrigeration and air conditioning systems. This direct-acting, modulating control valve automatically diverts high-pressure discharge gas to the low side of the system, maintaining a minimum evaporator pressure even during low-load conditions. Featuring a 1/2" ODF solder connection and a 0-30 PSI pressure range, it prevents common issues such as coil icing and short-cycling, which can significantly stress the compressor. The externally equalized design uses a 1/4" ODF connection to sense suction pressure accurately, ensuring the valve modulates effectively to keep the system balanced. Built with a durable brass body and a stainless steel diaphragm, this Parker Sporlan bypass valve is a reliable alternative to complex cylinder unloaders for systems typically up to 10 HP. Its 1/4" port size is optimized for stable hot gas bypass, protecting the compressor from operating outside its design parameters while enhancing overall humidity and temperature control.
Key Benefits for HVACR Technicians:- Enhanced Compressor Protection: Prevents low suction pressure and evaporator freezing by maintaining a stable minimum pressure during reduced load cycles.
- Precise Modulation: The adjustable 0-30 PSI range allows for fine-tuning based on specific system requirements and evaporator saturation temperatures.
- Reliable Construction: Features a robust brass body and knife-edge metal-to-metal joints to ensure leak-free performance under high-pressure conditions up to 500 PSI.
- Universal Application: Compatible with various refrigerant distribution methods, including bypass to the evaporator inlet through a side connection distributor or directly into the suction line.
- Simplified Capacity Control: Offers a cost-effective solution for unloading requirements on smaller systems where mechanical cylinder unloading is impractical.
How do I set the opening point for the ADRSE-2?
Bypass valves should be set at the pressure equivalent to the minimum allowable evaporating temperature. Adjustments are made by turning the adjusting screw; clockwise increases the pressure setting, and counter-clockwise decreases it.
Does this valve require a solenoid valve for pump-down?
Yes, for systems requiring pump-down control, a solenoid valve must be installed upstream of the Sporlan 903322P, as the valve is normally closed during standard operation and Only opens when suction pressure drops below the setpoint.
Can I install this in a vertical line?
The valve can be installed in either horizontal or vertical refrigerant lines. However, technicians should ensure it is situated to prevent it from acting as an oil trap and to avoid solder flow into internal components during the brazing process.
