PRODUCT OVERVIEW

The NAKAKITA NS705-D functions as an electrically actuated pneumatic switching valve. When electrical power is applied to the solenoid coil, the valve changes position and directs compressed air or process media to the designated outlet port.

When the electrical signal is removed, the valve automatically returns to its normal operating position according to its internal spring-return mechanism.

This operating principle allows the valve to be used in numerous marine control applications where automatic actuation and remote control are required.

Typical applications include:

  • Boiler Burner Control Systems
  • Marine Automation Systems
  • Pneumatic Actuator Systems
  • Fuel Oil Control Systems
  • Engine Room Control Systems
  • Safety Shutdown Systems
  • Cargo Control Systems
  • Air Control Circuits
  • Valve Positioning Systems

The valve provides dependable switching performance and is designed to operate continuously within demanding marine environments.
