Product Overview
The SIEMENS 8402740 is a high-precision solenoid-operated process and pneumatic valve engineered for demanding industrial fluid control applications. As a direct-acting, normally closed (NC) two-way solenoid valve, it utilizes an electromagnetic coil to actuate an internal plunger, providing reliable on/off control of compatible media including compressed air, inert gases, water, and light hydraulic fluids. The 8402740 is designed for seamless integration into automated process lines, offering fast response times, low power consumption, and a compact, robust construction that ensures long-term operational stability in continuous-duty cycles.
