Description
The Trane VAL11138 Expansion Gear Valve D3.2 1000 2000 is a refrigerant control part that modulates fluid circulation to maintain proper system balance and efficient operation. It operates through a gear-driven mechanism that adjusts passage based on system demand, ensuring controlled distribution to the evaporator for stable performance and component protection. In HVAC systems, it is used in air conditioning and heat pump units to optimize cooling and heating efficiency. It is mounted within the circuit between the liquid line and vaporizer section and supports accurate flow control and improved efficiency.
