Allied Air 1.851365 Txv Kit H4TXV03

Product Description

The ALLIED AIR 1.851365 is a thermostatic expansion valve (TXV) kit, model H4TXV03, designed to regulate refrigerant flow into the evaporator coil of a split-system air conditioning or heat pump system. The TXV meters refrigerant based on superheat at the evaporator outlet, maintaining efficient and stable system performance across varying load conditions. This kit is intended for installation by licensed HVAC technicians as part of a new installation or a retrofit service call where the existing metering device requires replacement.

This TXV kit is suited for residential and light commercial HVAC applications where precise refrigerant metering is required. The H4TXV03 designation identifies the specific valve configuration within the ALLIED AIR product line. It is typically installed at the indoor coil as part of a split-system cooling or heat pump circuit. Technicians sourcing a direct OEM-style replacement for an existing valve assembly will find this kit appropriate for applicable Allied Air equipment.
