MRCOOL Replacement Gas Side King Valve – Part #15500204000049
For DIY-MULTI4-36HP230C & DIY-MULTI5-48HP230C Multi-Zone Condensers
The MRCOOL Gas Side King Valve (Low-Pressure Valve), part number 15500204000049, is a genuine OEM replacement component designed specifically for MRCOOL multi-zone condensers, including:
- DIY-MULTI4-36HP230C (4-Zone, 36k BTU)
- DIY-MULTI5-48HP230C (5-Zone, 48k BTU)
This gas-side service valve plays a critical role in refrigerant flow regulation within the outdoor condenser unit. Proper low-pressure control is essential for maintaining system performance, efficiency, and long-term reliability in multi-zone ductless mini split systems.
What the Gas Side King Valve Does
Often referred to as a low-pressure service valve, the king valve regulates refrigerant flow on the suction (gas) side of the system. Its primary functions include:
- Controlling refrigerant movement during operation
- Allowing isolation of the condenser during service
- Supporting proper pressure balancing in multi-zone applications
- Enabling system charging, evacuation, and maintenance procedures
In multi-zone systems, maintaining proper low-pressure regulation is vital for compressor protection, refrigerant stability, and overall HVAC efficiency.
