German COEM valves COEM models COEM prices

COEM valves can automatically open and close based on the system's working pressure. They are generally installed on equipment or pipelines in closed systems to protect system safety. When the pressure inside the equipment or pipeline exceeds the set pressure of the relief valve, it automatically opens to relieve pressure, ensuring that the medium pressure in the equipment and pipeline remains below the set pressure, thereby protecting the equipment and pipeline and preventing accidents. The working principle of COEM valves is a type of hydraulic control valve. The main valve is divided into upper and lower parts by a diaphragm. The lower chamber of the diaphragm serves as the water flow passage, while the upper chamber acts as the control room, which controls the opening and closing of the main valve disc. The pilot valve itself is a relief
