Sporlan 901093P Valve

The Sporlan 901093P is a heavy-duty, direct-acting ORIT-6 evaporator pressure regulator designed specifically for commercial refrigeration and HVAC systems. Built with a 1/2" ODF solder connection and a hermetic brass construction, this valve excels at preventing coil freezing by maintaining a constant evaporator pressure regardless of fluctuations in the suction line. With an adjustment range of 0/50 psi, it allows veteran techs to dial in precise saturated temperatures, making it an essential component for multitemperature systems, food display cases, and water chillers. This EPR valve operates by modulating closed as evaporator load decreases, ensuring the system capacity remains balanced without the need for high-side pilot gas. The inclusion of a standard inlet pressure tap simplifies field diagnostics, while the extended copper leads facilitate a clean, leak-free brazing process. For contractors looking to improve humidity control or eliminate frost accumulation on air coils, the Sporlan ORIT-6 provides field-proven reliability in a compact, maintenance-free footprint.

• Precise Pressure Management: Features a 0.55 bar sensitivity for the 0-50 psi range, ensuring accurate evaporator temperature control.
• Superior Construction: Hermetic brass body with a 1/2" ODF sweat connection eliminates the risk of gasket failure and leaks.
• Integrated Service Features: Comes standard with an inlet pressure tap for rapid gauge readings and troubleshooting.
• High System Stability: Prevents low-pressure conditions that lead to compressor flooding and inefficient heat absorption.
• Broad Compatibility: Suitable for a wide range of refrigerants including R-22, R-134a, and R-404A in standard commercial applications.

• How does this valve prevent evaporator icing? By functioning as an inlet pressure regulator, it throttles the suction gas to keep the internal pressure—and thus the coil temperature—above the freezing point.
• Is this suitable for a multi-evaporator rack system? Yes, the ORIT-6 is commonly used on multi-temp racks to allow individual evaporators to run at different saturated temperatures despite sharing a common suction header.
• Can I adjust the pressure setting under load? Absolutely. The 0/50 psi adjustment range is field-tunable via the screw on the spring housing to match specific load requirements.
