NAKAKITA NS692N 6 AGB 50 AC 100 V SOLENOIDÂ VALVE
The NAKAKITA NS692N is a compact, direct-acting solenoid valve designed for controlling the flow of general-purpose fluids and air. The specific model code provides all the key technical specifications.
Here is a breakdown of what each part of the model number means:
-
NAKAKITA: The manufacturer, a reputable Japanese company known for its precision valves and control equipment.
-
NS692N: The base model series. This indicates a specific design, body type, and internal construction.
-
6: Port Size. This valve has Rc (PT) 1/8″ internal threaded ports.
-
AGB:Â Valve Type and Seal Material.
-
A: Standard, general-purpose model.
-
G:Â Gasket Material is FKM (Fluorocarbon Rubber/Viton). This makes it resistant to a wide range of chemicals, oils, and high temperatures.
-
B: Likely denotes a specific internal configuration or spool type (common in 3-port valves).
-
-
50: Voltage/Frequency Code. This code corresponds to AC 100V, 50/60Hz.
-
AC 100V: The operating voltage is 100 Volts Alternating Current. It is crucial to use this valve with a 100V AC power supply.
-
(Implied) 3-Port, 2-Position: The “B” in the model code and the NS692 series typically indicates a 3-port (3-way), 2-position valve. This is a very common configuration used for functions like:
-
Single-acting cylinder control (extend or retract using air pressure).
-
Selecting between two pressure sources.
-
Diverting flow from one outlet to another.

Detailed Product Specifications
| Feature | Specification |
|---|---|
| Model | NAKAKITA NS692N 6 AGB 50 |
| Valve Type | 3-Port (3-Way), 2-Position Solenoid Valve |
| Operation Type | Direct-Acting (The solenoid coil directly opens/closes the orifice without needing a pressure differential). |
| Port Size | Rc (PT) 1/8″ (6mm) |
| Pipe Connection | Internal Tapered Thread (Rc / PT) |
| Operating Principle | Single Solenoid, Spring Return (The valve shifts when energized and returns to its default position when de-energized). |
| Voltage | AC 100V, 50/60Hz |
| Seal Material | FKM (Viton)Â – Excellent resistance to heat, oil, and many chemicals. |
| Body Material | Die-Cast Zinc (common for this series) |
| Spool Type | Single Solenoid, Spring Return |
| Fluid Media | Air, Water, Inert Gases, Light Oils (compatible with FKM seals) |
| Operating Pressure | 0 to 0.7 MPa (0 to ~100 psi) –Â Confirm exact range in the manual as it can vary by media. |
| Temperature Range | -5°C to +60°C (Fluid and Ambient) – FKM allows for a higher fluid temp, but this is a general range. |
| Duty Cycle | Continuous (100%) |
| Protection Class | Typically IP65 (Dust-tight and protected against water jets) –Â Standard for industrial solenoid valves. |
Function and How It Works
As a 3-port, 2-position, spring-return solenoid valve:
-
Default State (De-energized):Â The spring holds the internal spool in its normal position. In this state:
-
Port P (Pressure) is blocked.
-
Port A (Actuator) is connected to Port R (Exhaust).
-
-
Activated State (Energized):Â When power (100V AC) is applied to the coil, the solenoid creates a magnetic force that pulls the plunger, shifting the spool. In this state:
-
Port P (Pressure) is connected to Port A (Actuator).
-
Port R (Exhaust) is blocked.
-
Typical Applications
This valve is commonly used in:
-
Industrial Automation:Â For controlling pneumatic cylinders, actuators, and grippers.
-
Machine Tools:Â Operating clamps, stops, and ejectors.
-
Packaging Machinery:Â Air control for filling, sealing, and labeling.
-
Water Treatment Systems:Â Controlling water or chemical dosing.
-
Any equipment requiring compact, reliable on/off or diverting fluid control with a 100V AC power source.
