The BARRY E WALTER SR COMPANY KL55-Y010 is a hot add-on valve assembly designed for use in HVAC and refrigeration systems where charging or add-on faucet function is required. This assembly controls refrigerant or fluid flow at a service or add-on connection point, allowing technicians to service, charge, or expand system capacity without full system shutdown. It ships at 1 pound, making it a compact, lightweight component suited for field installation by licensed HVAC or refrigeration technicians. The KL55-Y010 is a direct replacement-style assembly built to restore proper valve function at the add-on or charging port.
This valve assembly is typically used in residential and light commercial HVAC or refrigeration applications where an add-on charging function is integrated into the system piping or manifold. It is appropriate for installations requiring a dedicated service or charge port valve, and is installed by licensed HVAC technicians during routine service, system expansion, or component replacement procedures.
Designed as an OEM-style replacement valve assembly for HVAC and refrigeration systems requiring a hot add-on or charging port valve function.
Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable local codes and EPA Section 608 refrigerant handling regulations. Recover all system refrigerant and relieve system pressure before removing or installing any valve assembly. Ensure all connections are leak-tested after installation before recharging the system.
