Industries in Japan Increase Investment in Manufacture and Assembly of Marine Actuators and Valves

Marine Actuators and Valves


 Marine actuators and valves are devices that serve to move and control a system or mechanism, such as by opening a particular valve. In plain English, it is a "motion controller". There are several different types of actuators, depending on the need they fill. Actuators have two major types, which are known as mechanical actuators and hydraulic actuators. Mechanic actuators are designed to create movement in a fluid or other medium and to change the shape of it by impinging upon the boundary.

Hydraulic actuators use hydraulic diaphragms that force the fluid to move and change its shape.  Electro-hydraulic actuators and hydraulic cylinders may be similar in size and find application in outdoor equipment, marine, military, aerospace and many other fields. Other types of marine actuators and valves include, pneumatic, electric, and thermal or magnetic. Electric actuators can be further classified into electromechanical actuator, electrohydraulic actuator, and linear motor. In February 2021, Thomson Industries, Inc., a manufacturer of linear motion control solutions that operates in the U.S., Japan, Germany, and other countries, launched the Electrak LL electric linear actuator.

Japan is witnessing increasing investment in manufacturing of marine actuators and valves. In February 2021, Nikkiso Cryogenic Industries’ Clean Energy & Industrial Gases Group, a subsidiary of Nikkiso Co., Ltd (Japan), announced their Pump Unit has acquired the intellectual property to manufacture and assemble electric-mechanical actuators and the associated control panels. Electric gage actuators are easy to install and eliminate problems associated with the conventional pneumatic solutions. They reduce maintenance time and cost and provide gaging solutions with consistent, fast and precise control of the process. In 2020, SMAC Moving Coil Actuators, the U.S.-based industrial equipment supplier, launched a series of electric gage actuators.
