Final answer:
Pressure reducing valves have three fluid ports: the inlet port, outlet port, and bypass port.
Step-by-step explanation:
In pressure reducing valves, there are three fluid ports in the body. These ports are commonly known as the inlet port, outlet port, and bypass port.
The inlet port is the point where the high-pressure fluid enters the valve body. It is typically connected to the supply line or system.
The outlet port is where the reduced pressure fluid exits the valve body. It is connected to the downstream system or equipment that requires the lower pressure.
The bypass port is a separate passage in the valve body that allows some of the fluid to flow through without being reduced in pressure. It is used to regulate the pressure difference between the inlet and outlet ports, ensuring balanced operation.
