The EG40 Series Solenoid Valves are normally closed gas control valves designed for civil and industrial applications, operating with alternating current (AC). These advanced valves feature a special rectifier circuit that delivers high inrush power during activation, ensuring fast, reliable performance while preventing coil overheating. This technology allows the use of smaller valve coils while maintaining high operating pressure values, making the EG40* valves compact yet powerful.

Key Features:

Normally Closed Design: Ensures the valve stays closed until energized, providing safe and secure gas control for various applications.

High Inrush Power Circuit: The valve’s rectifier circuit supplies high inrush power during startup (70W for fast opening, 138W for slow opening), then reduces power to maintain operation without overheating.

Fast or Slow Opening Options: Available in fast opening or slow opening models, with the latter equipped with a hydraulic shock absorber for smoother, controlled flow, preventing surges during operation.

Flow Adjustment & Initial Flow Control: These solenoid valves offer precise flow adjustment, including control over initial flow in fast-opening models, allowing for customizable performance based on specific application needs.

Integrated Wire-Net Filter: An inlet filter prevents dirt particles larger than 1 mm from entering the valve, ensuring long-lasting, reliable operation by keeping internal components free of debris.

By-Pass Solenoid Valve: The EG40 valves* can be fitted with an optional by-pass solenoid valve, eliminating the need for a separate by-pass installation. Both the main valve and the by-pass valve share the same inlet gas pipe but operate with different electrical controls, providing flexibility and efficiency.

Silent Operation: The integrated rectifier circuit allows the use of attenuators for quiet operation, making these valves ideal for environments where noise reduction is essential.

Pressure Plugs & Connection Flexibility: Equipped with pressure plugs both upstream and downstream, the valves enable easy pressure monitoring. The valves can also be connected using four screws and an O-ring, avoiding the need for threaded junctions and simplifying installation.

Flow Adjustment Instructions for EG40*SR Valves:

1. Remove the top protection by rotating it counterclockwise.
2. Turn the adjustment screw clockwise to reduce the flow.
3. Rotate the screw in the opposite direction to increase the flow as needed.

Applications:

• Industrial and Commercial Gas Systems
• HVAC Systems
• Gas Safety and Pressure Regulation
• Industrial Burners and Boilers
• Civil Gas Control Installations

Customizable & High-Performance:

The EG40 Series Solenoid Valves provide a highly customizable and compact solution for gas control in both civil and industrial environments. Featuring options for fast or slow opening, flow adjustment, and by-pass valve integration, these valves are designed for precision, reliability, and long-term performance. The advanced rectification circuit ensures silent, efficient operation, making them suitable for a wide range of applications where noise reduction and durability are essential.
