The image shows a close-up of a pressure gauge, which is a type of valve used to measure the pressure of a liquid or gas system. The gauge is mounted on a metal frame with two pipes attached to it. On the left side of the frame, there is a brass-colored valve with a red handle and a black dial. The dial has the brand name "GRUNDFOS" written on it in white letters. Next to the valve, there are two orange-colored valves, one with a blue handle and the other with a black handle. The valves are connected to a metal pipe with a threaded end. The pipe appears to be made of metal and has a threaded connection at the bottom.
