Nordyne 669566R Expansion Valve Els PW 17895 Maintains consistent manifold pressure calibrationThe Nordyne 669566R Expansion Valve is a critical metered flow component designed specifically for high efficiency cooling systems using R410A refrigerant. As a 3 ton externally equalized TXV, this thermal expansion valve maintains a precise superheat balance across the evaporator coil, preventing liquid slugging and ensuring optimal compressor longevity. The 669566R serves as the direct replacement for Nordyne 669566, allowing for a seamless drop in
