Sporlan 901173 ORIT-6-30/100 5/8 OD Evaporator Pressure Regulating Valve

The Sporlan 901173 ORIT-6-30/100 is a heavy-duty, direct-acting evaporator pressure regulating valve engineered to maintain precise suction pressure control in commercial refrigeration and air conditioning systems. Designed for 5/8 ODF solder connections, this EPR valve features a 30 to 100 psi adjustment range and a robust 3/4-inch port to handle varying load requirements effectively. Its hermetic construction eliminates the need for gaskets or seals, significantly reducing the risk of refrigerant leaks while ensuring long-term reliability in the field. The ORIT-6 is specifically built with a corrosion-resistant brass body and a 40-mesh insertable inlet strainer to protect the internal metal-to-metal seat from debris. Whether you are managing multi-temperature evaporator systems or preventing coil icing in water chillers, this Sporlan valve provides the accurate modulation needed to balance system capacity with fluctuating loads. The integrated standard inlet pressure tap allows for streamlined field adjustments and diagnostic testing without additional line taps.

• Precise Pressure Regulation: Maintains constant evaporator pressure between 30 and 100 psi, preventing frost buildup on air coils and stabilizing humidity.
• Hermetic Reliability: Features a fully sealed, leak-free design with no gaskets, ideal for high-pressure systems rated up to 400 psi.
• Superior Debris Protection: Includes a factory-installed 40-mesh strainer on ODF models to safeguard internal components and ensure positive shut-off.
• Extended Service Life: Constructed with a high-grade brass bellows and copper connections for maximum durability in demanding HVACR environments.
• Ease of Service: Built-in pressure tap allows technicians to quickly verify settings and perform accurate system tuning.

How do I adjust the pressure setting on the ORIT-6-30/100?
Remove the cap and turn the adjusting stem clockwise to increase the pressure setting or counterclockwise to decrease it. For precision, always use a calibrated gauge manifold connected to the standard inlet pressure tap during the process.

What is the primary function of an EPR valve in a multi-evaporator system?
The valve modulates toward the closed position when the load decreases, preventing the evaporator pressure from falling below your setpoint. This allows multiple evaporators to operate at different temperatures while connected to a single suction header.

Can this valve be used with modern HFC and HCFC refrigerants?
Yes, the Sporlan ORIT series is compatible with all common HFC and HCFC refrigerants and blends. Always verify that your specific refrigerant’s pressure-temperature profile aligns with the 30-100 psi adjustment range for your application.
