Featured Component: Madas EVPS/NC DN20 Solenoid Valve
The Riello 40 FS10 and FS20 series now feature the Madas EVPS/NC S15 DN 20 as a standard-issue gas solenoid valve. This high-specification Italian component is a normally closed (NC) automatic valve specifically engineered for precise gas control and slow-opening safety.
Technical Highlights:
-
Model: EVPS/NC S15 DN 20 (DN20 – 3/4″ Threaded).
-
Max Operating Pressure: 360 mbar (36 kPa), optimized for standard industrial gas pressure requirements.
-
Safety Class: Class A certified according to EN 161 (Group 2).
-
Protection Rating: IP65, providing superior dust and water resistance for industrial safety.
-
Adjustable Controls: Features dedicated dials for Opening Time and Rapid Initial Stroke to customize the startup sequence.
Core Advantages:
-
Soft-Start Technology: The EVPS (Slow Opening) design prevents sudden pressure surges during ignition, protecting the burner components and ensuring a smooth flame startup.
-
Precision Flow Management: Integrated with a Flow Regulation adjustment system, allowing technicians to fine-tune the maximum gas delivery directly at the valve.
-
Fail-Safe Shut-off: As a normally closed (NC) valve, it provides a reliable, high-speed shut-off (<1 second) whenever power is interrupted, meeting the strictest safety regulations.
-
Compact Industrial Grade: The die-cast aluminum body and high-efficiency coil are built for a wide operating temperature range (-20°C to +60°C), perfectly matching the Riello 40 series’ durability.
