When using metal valves with seawater or chemical solutions, durability issues due to corrosion are inevitable, and it is often seen that cases use resin valves, which are weak against vibrations. Therefore, our company has successfully developed a highly durable (3 million cycles) metal "solenoid valve" that can be used for a long time even with seawater and chemical solutions.

When using metal valves in seawater, issues related to corrosion and durability inevitably arise, leading to a frequent use of resin valves, which are vulnerable to vibrations. In response, our company has developed metal valves for seawater that can be used for extended periods: "solenoid valves, flow control valves, and air release valves," achieving significant total cost reductions compared to resin. 【Countermeasure Introduction】 ■ Solenoid Valve: Diaphragm structure that blocks fluid entry to the movable iron core. ■ Flow Control Valve: Corrosion measures including a special coating on the spring. ■ Air Release Valve: Incorporates a ball in the valve body and our unique crystallization countermeasures. In addition to these three products, we also offer a variety of valves compatible with seawater and special fluids, including check valves! We are actively engaged in new product development and have established a system to assist you when you encounter difficulties. For more details, please refer to our catalog or feel free to contact us.
