Product Overview
The SIRAI L182B01 is a pilot-operated (servo-assisted) 2/2-way solenoid valve engineered by SIRAI (a brand of Emerson) for precise on/off control of neutral and lightly aggressive media in industrial process and pneumatic circuits. The valve utilizes a diaphragm-type pilot architecture in which the solenoid pilot orifice controls the pressure differential across the main diaphragm, allowing the line pressure itself to actuate the main seal. This design permits high flow rates through a compact body while requiring only a low-power coil for actuation. The L182B01 features a G3/4 threaded port connection and is configured with an 18 mm orifice, making it suitable for medium-flow dosing, shut-off, and diverting duties in water treatment, compressed air systems, and general industrial fluid handling. As a pilot-operated device, it requires a minimum differential pressure to open and is not a direct-acting valve.

Engineering Features & Advantages
- Pilot-Operated Efficiency: The servo-assisted diaphragm design uses line pressure to drive the main seal, enabling high flow capacity with minimal coil power and heat generation.
- Precise On/Off Control: Fast, reliable response for process dosing, shut-off, and pneumatic switching duties with consistent repeatability.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust diaphragm and coil construction resistant to wear and media contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SIRAI L182 series mounting and port standards for drop-in service.
Typical Industrial Applications
Water and wastewater treatment systems, compressed air and pneumatic control panels, industrial washing and cleaning equipment, chemical dosing and neutral media transfer skids, and general process fluid shut-off in manufacturing plants.
