NACHI SA Series Wet Type Solenoid Operated Directional Control Valve (G01)
Made in: Japan
Manufacturer: NACHI
Model: SA Series (G01)
Features
Recognized by reliable overseas safety standards such as CE (Europe), UL (U.S.A.) and CSA (Canada).
The power consumption of the DC solenoid (D* and E*) is reduced. This will further promote your energy saving policy.
An innovative fluid reaction compensating mechanism assures reliable valve switching. (Patent pending)
Interchangeable with conventional products (30 designs)
The valve proper as well as such parts as a coil are interchangeable with the conventional ones in terms of a kit.
