Description
Parker-Sporlan OSE-21-SX35 Thermostatic Expansion Valve
The Parker-Sporlan OSE-21-SX35 (SKU 124231P) is a high-performance externally equalized thermostatic expansion valve (TXV) engineered for reliable refrigerant flow control in commercial and industrial refrigeration and air conditioning systems. Designed and manufactured by Parker-Sporlan — a globally recognized leader in refrigeration controls — this valve delivers precise superheat regulation to maximize system efficiency and protect the compressor from liquid slugging.
Product Overview
The OSE series expansion valves from Parker-Sporlan are built for demanding HVAC/R applications where accurate metering of refrigerant is critical. The external equalizer design compensates for pressure drop across the evaporator, ensuring consistent superheat control even in systems with longer or more complex evaporator circuits. The SX35 designation identifies the specific refrigerant and capacity configuration for this valve.
