Sporlan 902929P Control

The Sporlan 902929P (Type OROA-5) is a high-performance head pressure control valve designed to maintain critical system stability during low ambient conditions. This non-adjustable regulator combines the functionality of an ORI and ORD valve into a single hermetic brass body, featuring 7/8" ODF connections and a factory-set 210 PSI operating point. By restricting liquid refrigerant flow from the condenser while simultaneously diverting hot gas to the receiver, the Sporlan OROA-5 ensures a consistent pressure differential across the thermostatic expansion valve (TXV), preventing evaporator icing and compressor short-cycling.

Engineered for contractors who require reliable HVAC head pressure control, this unit utilizes a durable stainless steel diaphragm and metal-to-metal seating to withstand a maximum rated pressure of 450 psig. The 7/8 inch ODF head pressure valve simplifies piping by eliminating the need for separate components, making it an ideal choice for commercial refrigeration and air conditioning units with remote condensers. Natural refrigerant flow modulation helps maintain refrigeration receiver pressure, ensuring the system reaches a stable steady-state even when outdoor temperatures drop significantly.

• Integrated ORD Functionality: Automatically bypasses hot gas to the receiver to ensure immediate high-side pressure recovery.
• Hermetic Construction: Robust brass body and copper connections prevent leaks in high-vibration commercial environments.
• Optimized 210# Setpoint: Specifically calibrated for high-pressure refrigerants to maintain proper liquid line subcooling.
• Reduced Installation Complexity: The three-way modulating design replaces multiple valves, reducing potential leak points and labor time.
• Stainless Steel Diaphragm: Provides superior longevity and precise response to outlet pressure variations.

Is the Sporlan OROA-5 adjustable?
No, this is a non-adjustable, factory-set control. For the 902929P model, the pressure is fixed at 210 PSI to ensure consistent performance without the risk of field tampering.

What is the maximum working pressure for this valve?
The OROA-5 series is rated for a maximum rated pressure (MRP) of 450 psig, making it suitable for a wide range of standard refrigeration applications.

Can I use this with any refrigerant?
The 210# setting is typically used with refrigerants like R-22 or R-404A depending on the desired saturated condensing temperature, but you should always verify the pressure requirements of your specific system and refrigerant type.
