4-Way جسم الصمام من De Dietrich 767835200

The 4-way valve body is a crucial component in reversible heat pumps and some hydronic systems, allowing the direction of refrigerant or water flow to be changed for heating or cooling modes. This valve body is typically made of brass or steel and contains internal passages that redirect flow when the valve is actuated. A faulty valve body can cause the system to get stuck in one mode or lead to inefficient operation. When replacing, it is important to choose a valve body that matches the port sizes and connection types of your system. Regular maintenance of this component helps ensure year-round comfort.
