Sporlan 124819 Thermostatic Expansion Valve 30 Ton R404A 1-1/8 Inches X 1-3/8 Inches Odf

Product Description

The Sporlan 124819 is a 30-ton thermostatic expansion valve designed for R404A refrigeration and air conditioning systems. It carries the model designation OSE-30-C and features ODF solder connections for straightforward field installation. This valve handles a nominal capacity of 360,000 BTU per hour, making it well-suited for large commercial refrigeration units, walk-in coolers, and industrial air conditioning systems where precise refrigerant flow control is critical. HVAC and refrigeration technicians rely on thermostatic expansion valves to meter liquid refrigerant into the evaporator coil. By responding to suction line temperature and pressure, the TXV maintains the correct superheat at the evaporator outlet, protecting the compressor from liquid slugging and improving overall system efficiency. The Sporlan 124819 uses external equalization, which means the valve sensing bulb and evaporator outlet pressure work together to accurately control flow even in systems with significant pressure drop across the evaporator. This makes it especially effective in larger coil configurations common in commercial refrigeration. The valve body is constructed of brass bar stock and features a Type O balanced port design. Balanced port construction reduces the effect of inlet pressure fluctuations on valve operation, providing more stable superheat control across a wide range of operating conditions. The thermostatic element uses a C-type charge and is field-replaceable, allowing technicians to service the valve without replacing the entire assembly. The inlet connection includes a permanent 12 mesh strainer that filters debris before it can enter the valve seat, protecting system components downstream. A synthetic seating surface ensures tight shut-off during system off cycles, preventing refrigerant migration into the evaporator when the system is not running. The inlet is 1-1/8 inches ODF and the outlet is 1-3/8 inches ODF. The evaporator equalizer port is 1/4 inches ODF. Maximum operating pressure is 450 PSI. Capillary tube length is 60 inches. This valve is manufactured by Parker Hannifin Corporation under the Sporlan brand, a trusted name in refrigeration flow controls.
