Sporlan 125384 Valve

The Sporlan 125384 is a premier OZE-25-GA thermostatic expansion valve designed for high-capacity R-410A refrigeration and air conditioning systems. Featuring a balanced port design, this valve ensures precise refrigerant flow control by neutralizing the effects of erratic head pressures and varying evaporator loads, making it ideal for commercial HVAC applications and industrial chillers. The OZE-25GA is engineered with a 7/8 x 1-3/8 ODF solder connection and a 25-ton nominal capacity, providing the robust performance required for heavy-duty thermal expansion valve replacements.

Built with a brass bar stock body and a 60-inch capillary tube, this externally equalized TXV (1/4" ODF) allows for fine-tuned superheat adjustment to maximize evaporator efficiency. The stainless steel diaphragm and replaceable power element offer long-term durability in demanding environments. This 25-ton expansion valve is a direct technical match for model OZE-25GA, ensuring seamless integration into existing HVAC/R piping configurations where reliable liquid line metering is critical for system stability.

Key Benefits

• Balanced Port Design: Maintains consistent superheat levels even during significant pressure fluctuations across the valve.
• R-410A Optimized: Specifically calibrated with a GA thermostatic charge for superior performance in modern high-pressure air conditioning systems.
• Serviceable Construction: Features accessible internal parts and a durable brass bar stock body for easier maintenance and inspection.
• Extended ODF Connections: Simplifies the soldering process by providing 7/8" x 1-3/8" ODF sweat connections that reduce heat transfer to internal components during installation.

Common Questions

• Is the Sporlan 125384 compatible with bi-directional flow? While many Sporlan O series valves support bi-directional flow, always check your specific system's piping layout to ensure proper check-valve placement or internal configuration for heat pump applications.
• What is the primary function of the external equalizer on this model? The 1/4" ODF external equalizer compensates for the pressure drop across the evaporator, ensuring the TXV senses the correct pressure at the coil outlet for accurate superheat control.
• Can replace an older OZE-25GA with the 125384? Yes, the 125384 is the identical manufacturer part number for the OZE-25GA specification, ensuring 100% mechanical and functional compatibility.
