Description

This is a block-type thermal expansion valve designed for heavy-duty air conditioning systems. It regulates the flow of refrigerant into the evaporator based on the cooling load, ensuring efficient system operation. Block expansion valves are commonly used in auxiliary systems and can be 'nicked' or 'bleed' types to prevent oil trapping when the main system is off.
