The Nakakita Seisakusho NS737S-D is a pneumatic positioner rated for a 0.2~1.0 kgf/cm2 input signal, used in shipboard control systems to drive pneumatically operated control valves. It takes the control signal and delivers an output pressure of 0.4~2.0 kgf/cm2 from a supply of 2.4 kgf/cm2, matching valve actuator position to the demand from the controller. Positioners of this kind are found on valves governing steam, fuel, cooling water and other process lines in the engine room. Made in Japan and marked 244335 D, the unit comes in New Open Box condition.
