SOL3A1 is a pilot-operated 2-way solenoid valve designed for industrial fluid control in liquid or gas applications. It features a normally open (NO) configuration with 24Vdc operation, a forged brass body with magnetic stainless steel plunger, and G3/4" BSP port size (DN 18). The valve operates across a fluid temperature range of -20°C to +90°C with a maximum room temperature of 80°C, and is rated for continuous service with VDE-approved coil and IP65 protection class. With a minimum pressure of 0.2 bar and maximum flow capacity of 5 m³/hr, the SOL3A1 is ideal for use in autoclaves, cooling plant equipment, watering systems, fire extinguishing systems, and other industrial and commercial fluid control applications requiring reliable pilot-operated actuation.
