SOL4B1 is a pilot-operated 2-way solenoid valve designed for industrial fluid and gas control applications. It features a G1" BSP port size with a nominal diameter (DN) of 26 mm, forged brass body construction, and normally open (NO) operation. The valve operates with a minimum pressure of 0.2 bar and a maximum pressure of 12 bar, delivering a maximum flow rate of 11 m³/hr. It is constructed with a magnetic stainless steel plunger, NBR gaskets, and operates continuously across a fluid temperature range of -20°C to +90°C with a maximum ambient room temperature of 80°C. The SOL4B1 is ideal for use in autoclaves, cooling systems, watering equipment, fire extinguishing systems, and water jet machinery, providing reliable pilot-operated control for diverse industrial and commercial applications.
