Sporlan 903005P Valve

The Sporlan 903005P (Model LAC-4-210) is a three-way modulating head pressure control valve engineered for consistent performance in low ambient conditions. Designed specifically for HVACR systems utilizing R-404A, R-507, and R-402A refrigerants, this low ambient control maintains a fixed setting of 210 PSI to prevent the common pitfalls of insufficient head pressure, such as liquid migration or evaporator icing. Featuring 3/8" ODF solder connections and a 1/2" port, the Sporlan LAC-4-210 simplifies piping by combining the functions of a condenser pressure regulator and a receiver pressure regulator into a single, compact brass body.

Built for reliability in commercial refrigeration and air conditioning units, the 903005P head pressure controller limits refrigerant flow from the condenser while simultaneously diverting hot gas to the receiver inlet. This operation stabilizes the discharge pressure, ensuring the thermostatic expansion valve (TEV) receives the necessary pressure differential for precise refrigerant metering. With a 500 PSI maximum rated pressure and a durable domed steel element, this valve is a critical component for technicians looking to maintain system efficiency and protect compressors from unnecessary cycling during cold weather operation.

• Optimized Pressure Stability: Precisely maintains 210 PSI head pressure to ensure reliable TEV operation.
• System Longevity: Prevents low suction pressure and compressor short-cycling in low-ambient environments.
• Robust Design: Features a high-quality brass body with copper 3/8" ODF connections and a metal-to-metal seat for leak-free performance.
• Compact Installation: Three-way modulating design reduces the need for multiple valves, lowering labor and material costs for the contractor.

• What refrigerants are compatible with the LAC-4-210? This 210 PSI model is primarily used with high-pressure refrigerants like R-404A and R-507.
• Does the valve come with an inlet strainer? No, the 903005P is a "less strainer" (LS) model; technicians should install an external strainer if debris is a concern.
• Where is the best place to install this valve? It should be installed in the liquid line between the condenser and the receiver for proper modulation.
