Sporlan 903106P Valve

The Sporlan 903106P, also identified as the LAC-10-295HP, is a heavy-duty head pressure control valve engineered for consistent refrigerant flow in low-ambient conditions. This three-way modulating valve responds directly to receiver pressure, utilizing a 295 PSI factory setting to bypass the condenser when pressures drop below the setpoint. By diverting discharge gas to the receiver and flooding the condenser, it effectively maintains the necessary pressure differential across the thermostatic expansion valve (TEV) to prevent evaporator starving. Built with a rugged brass body and 1-3/8" x 7/8" x 7/8" ODF solder connections, this Sporlan 903106P LAC-10-295HP is a direct functional equivalent to the 903106, ensuring seamless integration into commercial refrigeration and HVAC systems. Professionals trust the Sporlan refrigeration valve for its reliable low ambient control, industrial-grade copper connections, and ability to optimize system performance across fluctuating seasonal temperatures without the need for manual adjustments.

Key Benefits:

• Maintains System Stability: Ensures high-side pressure remains sufficient for TEV operation during winter or low-load cycles.
• Direct Compatibility: The Sporlan 903106P is identical to the 903106, providing a precise drop-in replacement for existing LAC-10 series configurations.
• Optimized Performance: Features a high-pressure 295 PSI setting to accommodate modern high-pressure refrigerants and demanding industrial applications.
• Durable Construction: High-quality brass housing with ODF connection points designed for leak-free, high-vibration environments.
• Automated Regulation: Modulates gas flow automatically based on receiver pressure, eliminating the need for complex electronic controllers in head pressure control loops.

Common Questions:

How do I confirm if my LAC-10-295HP is failing?
If the ambient temperature is below 70°F and the head pressure remains low, check the line between the valve and the receiver. If this line is cold, the valve is failing to bypass discharge gas. Conversely, if head pressure is low but the line is hot and the system is properly charged, the internal diaphragm or seat may be compromised.

Does the 903106P require a specific mounting orientation?
While the LAC-10 can be installed in various positions, it is critical to install a check valve in the drop leg between the LAC and the receiver to prevent refrigerant migration during the off-cycle, especially in systems with large charge volumes.

Is there a difference between the 903106 and 903106P?
No, 903106P is identical to 903106. The "P" suffix often denotes specific packaging or internal part numbering, but the technical specifications, ODF sizing, and 295 PSI pressure settings are exactly the same.
