Sporlan 109550 FVE-2-ZP Expansion Valve

The Sporlan 109550 FVE-2-ZP Expansion Valve is a reliable thermostatic expansion valve (TEV) designed for technicians who require precision superheat control in low-temperature refrigeration applications. Featuring a Type ZP thermostatic charge, this valve is specifically engineered to provide a Maximum Operating Pressure (MOP) limit, which effectively prevents motor overloading during high-load start-ups. Built with a durable brass bar stock body and SAE flare connections, the FVE-2-ZP ensures a leak-proof seal and remains field-serviceable with accessible internal parts. Its external equalizer and large flat stainless steel diaphragm allow for stable modulation and accurate refrigerant metering, even under fluctuating load conditions. This OEM Sporlan 109550 model is ideal for maintaining evaporator efficiency in walk-in coolers, freezers, and industrial displays where protecting the compressor from liquid flood-back and excessive suction pressure is a technical priority. Rely on this 2-ton expansion valve for consistent performance and rugged field longevity in harsh HVACR environments.

Key Benefits

• MOP Charge Protection: The ZP charge provides a pressure limit to protect the compressor motor from drawing excessive current during hot pull-downs.
• Precise Superheat Control: Features an externally adjustable stem to fine-tune system superheat for maximum evaporator efficiency.
• Serviceable Design: The replacement power element and removable 100-mesh inlet strainer allow for easy cleaning and field maintenance without removing the valve body.
• Corrosion Resistance: High-grade brass construction and stainless steel internal components resist erosion and corrosion in high-moisture environments.
• Wide Compatibility: Optimized for standard refrigerants like R-22, ensuring stable performance across a variety of low-temp refrigeration cycles.

Common Questions

Can I use a ZP charge to replace a standard Z charge?
No, ZP charges are specifically designed for applications requiring an MOP limit to prevent motor overload. Using them as a direct replacement for standard Z charges without considering system pressure requirements may lead to improper refrigerant flow at certain temperatures.

Where should the external equalizer line be installed?
To ensure accurate pressure sensing, the external equalizer should be installed on the suction line immediately downstream from the TEV sensing bulb.

How do I know if the inlet strainer needs cleaning?
If you notice high superheat accompanied by low suction pressure and a frost pattern starting at the valve outlet rather than the evaporator, the 100-mesh strainer may be restricted by debris.
