SOL2B1 is a pilot-operated 2-way normally closed (NC) solenoid valve designed for industrial fluid control in applications such as autoclaves, cooling systems, watering equipment, and fire extinguishing systems. The valve features a forged brass body with a magnetic stainless steel plunger and operates on 24Vdc with 10W power consumption. It is suitable for both liquid and gas applications, with an operating temperature range of -20°C to +90°C and a maximum room temperature of 80°C. The valve incorporates pilot-operated technology where the electro-pilot controls pressure differential across the diaphragm to achieve reliable opening and closing, with DN tightness ensured by retaining spring load in the de-energized state. This design makes SOL2B1 ideal for applications requiring precise fluid control, safety-critical systems, and hygienic or sanitary environments where reliable valve operation is essential.
