Rittal 3397143 Expansion Valve

The Rittal 3397143 Expansion Valve is a replacement refrigerant metering component engineered for use in Rittal enclosure cooling and climate control systems. This expansion valve ships individually packaged, with a packaging unit of 1 pc(s), a unit weight of 0.3 kg, and a packaging quantity of 1 ea, making it a compact, lightweight part that is easy to handle, transport, and store during routine maintenance or service work. In a refrigeration circuit, an expansion valve regulates the flow and pressure of refrigerant as it passes from the condenser to the evaporator, which helps the cooling system maintain consistent, stable temperature control inside the enclosure. As a genuine Rittal part, this expansion valve is intended as a direct service replacement for compatible Rittal cooling equipment, supporting predictable performance after installation.

Key Features

Rittal 3397143 – Frequently Asked Questions

1) What does the Rittal 3397143 expansion valve actually do in an enclosure cooling unit?
It is the refrigerant metering component in the cooling circuit. The valve controls refrigerant flow and pressure as it moves from the condenser into the evaporator, which is what keeps enclosure temperature stable instead of swinging. If a Rittal cooling unit is icing up, short cycling, or no longer holding setpoint, the expansion valve is one of the circuit parts a refrigeration tech checks.
2) Is Rittal 3397143 an OEM part or an aftermarket substitute?
Genuine Rittal, supplied as a direct service replacement component for compatible Rittal cooling equipment. For MRO teams standardizing on OEM spares for climate control units, that is the distinction that matters, since refrigerant metering has to match the circuit it was designed for.
3) What part number do I order for a Rittal cooling unit expansion valve?
Rittal manufacturer part number 3397143. Quote that number when matching it against the spare parts list for your specific cooling unit model.
4) Can a plant electrician install the Rittal 3397143 expansion valve, or does it need a refrigeration tech?
Replacing an expansion valve means opening a sealed refrigerant circuit, so it is refrigeration work, not panel work. Recovery, brazing or fitting the valve into the line between condenser and evaporator, evacuation and recharge are all involved. Electrical crews typically pull and swap the whole cooling unit; a certified refrigeration tech does component-level work like this valve.
5) How many expansion valves come in a pack of Rittal 3397143?
One. The packaging unit is 1 pc and it ships 1 ea, so ordering a quantity of three gets you three valves. That single-unit packaging is why it works as a shelf spare for a maintenance crib rather than forcing a multi-pack buy.
