Siemens M3FB15LX/A 5/8" Hot Gas Bypass Valve 3.5 Cv

The Siemens M3FB15LX/A is a hot gas bypass valve designed for commercial refrigeration and air conditioning systems. This valve helps maintain stable system operation by regulating refrigerant flow during low-load conditions, preventing compressor short cycling and ensuring consistent evaporator pressure.

Key Specifications:

• Connection size: 5/8 inch ODF (sweat)
• Flow coefficient (Cv): 3.5
• Applications: Hot gas bypass in refrigeration systems
• Function: Maintains minimum evaporator load during light load conditions
• Construction: Brass body with durable internal components

This valve is essential for systems that experience varying load conditions, protecting the compressor from damage due to excessive cycling while maintaining proper system pressures. The 3.5 Cv rating provides adequate flow capacity for small to medium commercial refrigeration applications.
