71R8380 Red Dot Bulbless Block Type Expansion Valve – Anti-Trumpeting, 2 Ton

The Red Dot 71R8380 Bulbless Block Type Expansion Valve is a high-capacity, anti-trumpeting TXV designed for mobile HVAC systems that experience high refrigerant flow and noise-sensitive operation. Anti-trumpeting valves reduce pressure pulsation and noise at the expansion point, helping stabilize evaporator performance in larger systems.

This valve is specifically designed for Red Dot A/C Unit R-9777 and is commonly used in Freightliner Cascadia (2008–2011) and John Deere wheel loader applications. With a 2-ton capacity, female O-ring connections, and an 8°F superheat rating, the 71R8380 is well-suited for heavy-duty on-highway and off-highway equipment.
