The NACHI SAW-G01 is a high-reliability spool-type solenoid valve that integrates directional control and built-in monitoring switch, featuring a maximum working pressure of 35MPa, a flow rate range of 30-100L/min, and compliance with ISO 4401 mounting standards for safe hydraulic system control. Equipped with a DC24V monitoring switch and offering a shock-absorbing option, it delivers precise position feedback and adopts a DIN connector for easy wiring, making it ideal for safety-critical hydraulic applications and industrial machinery such as injection molding machines.

Product Description

Overview

The NACHI SAW-G01 is a spool-type directional control solenoid valve integrated with a monitoring switch, specifically designed to meet international machine safety standards like ISO 12100 and JIS B 9700. It combines basic solenoid valve control functions with reliable position monitoring capabilities, making it widely applicable in industrial hydraulic systems.

Mechanical Monitoring
Adopts a mechanical structure where the valve's operation directly triggers the switch. Minimal dead zones, almost zero temperature drift, and hysteresis ensure stable and accurate output.
Easy Installation & Maintenance
Utilizes standard DIN connectors for both solenoid coil and switch wiring, simplifying initial setup and enabling quick replacement during maintenance.
Functional Compatibility
Identical in performance and mounting footprint to the standard SA-G01 model, facilitating easy safety upgrades without modifying existing circuits.
Typical Application Scenarios

The SAW-G01 is ideal for hydraulic systems that demand precise control and safety verification. It is commonly used in machinery such as injection molding machines, die-casting machines, CNC machine tools, and forging equipment. The monitoring signals it outputs can be used for sequence control of the equipment and safety confirmation of key actions.

Frequently Asked Questions
What is the primary function of the NACHI SAW-G01 solenoid valve?
It is a spool-type directional control solenoid valve integrated with a mechanical monitoring switch designed to verify the physical position of the valve spool for safety compliance.
How does the mechanical monitoring system improve reliability?
Unlike inductive or proximity sensors, the mechanical structure directly links the spool movement to electrical contact state. This eliminates temperature drift and hysteresis, delivering high signal reliability.
Can the SAW-G01 replace standard SA-G01 valves?
Yes. Standard parameters and mounting patterns conform to the same interface standards, meaning it can directly replace the SA-G01 in configurations requiring spool position feedback.
What mounting standards does this valve conform to?
The valve complies with the standard international ISO 4401-03-02 mounting interface configurations.
What is the difference between standard and shock-absorbing models?
The standard models support working pressures up to 35 MPa, while shock-absorbing variants support up to 25 MPa but offer buffered spool transitions to minimize hydraulic shock in sensitive operations.
