PARKER Thermostatic Expansion Valves

Used in various air conditioning and refrigeration applications. Available in different connection types to ensure a tight seal. Internal check valve available in some models

Thermostatic expansion valves, often abbreviated as TXVs, TEVs or TX valves reduce refrigerant pressure from the condenser pressure to the evaporator pressure. These valves keep the evaporator active as they increase the flow of refrigerant at high capacity loads and reduce the flow at low capacity loads. Thermal expansion valves provide complete evaporation of liquid refrigerant in the evaporator, thus eliminating liquid slugging. Thermal expansion valves can tolerate variation in refrigerant charge, as they adapt the refrigerant flow for matching the heat load. These valves minimise coil starving & flood back problems by controlling accuracy.
