Marine solenoid valve is an electromagnetic valve used on ships, vessels, offshore drilling rigs, oil tankers, and other vessels to control media such as seawater and domestic water. Due to the fact that seawater is a complex electrolyte solution and contains a certain amount of oxygen, the principle of electrochemical corrosion is applicable to seawater corrosion, and most metal materials in seawater belong to depolarization corrosion, where oxygen is the depolarizing agent for seawater corrosion. So it is required that marine solenoid valves withstand the corrosion of seawater.

working principle:

Normally closed: When the solenoid valve is not powered, it is in a closed state. After being powered on, the solenoid valve opens.

Normally open: When the solenoid valve is not powered, it is in an open state, and when powered on, the solenoid valve closes.
