What is suction control valve?

A suction control valve (SCV) is a component commonly used in refrigeration and air conditioning systems to regulate the flow of refrigerant. It helps maintain optimal suction pressure by adjusting the amount of refrigerant entering the compressor based on system demands. This ensures efficient operation, prevents compressor damage, and enhances overall system performance. SCVs are particularly important in systems with variable loads, enabling better energy efficiency and reliability.
