Sms Tork S1000.03 1/2" Servo Assist General Purpose Solenoid Valve – 14.5 mm – 0-16 Bar – Brass | Normally Closed

The Sms Tork S1000.03 1/2" Servo Assist General Purpose Solenoid Valve is designed to provide reliable, long-lasting, and high-performance flow control in air, water, and gas applications. Thanks to its servo-assisted structure capable of operating at zero differential pressure (Δp = 0 bar), it can function stably even in closed systems and lines where the inlet and outlet pressures are equal. Its brass body and stainless steel casing-core structure offer a long service life in industrial environments.

This model, with a 14.5 mm orifice diameter, operates with high efficiency, especially in lines ranging from 3/8” to 1”. Pilot-operated and normally closed, the S1000 series solenoid valves are widely used in automation systems, process lines, water treatment plants, compressor systems, and gas applications.

About the S1000 Series

The S1000 Series Servo Assist Solenoid Valves are pilot-operated solenoid valves suitable for large-scale applications that can operate without differential pressure (zero pressure). The minimum inlet-outlet pressure difference Δp = 0 bar , and the maximum operating pressure is 16 bar. They can be safely used in closed systems where line pressures are equal.

3/8” – 1” sizes are suitable for air, water, gas, and liquid fluids. 1 1/4” – 2” sizes are recommended only for water and liquid fluid applications.

Areas of Application

• Industrial automation systems
• Process and fluid control lines
• Water treatment and distribution systems
• Pneumatic and compressor systems
• Gas pipelines and machinery manufacturing.
• Closed-loop and low-pressure systems
