This model operates as a normally closed safety valve that opens upon energization and closes tightly under both spring and diaphragm pressure when de-energized. Constructed from durable cast aluminum, the V48A2185 offers corrosion resistance and a lightweight design while maintaining structural strength for industrial gas piping. Its adjustable bleed orifice allows control of opening speed to match burner startup requirements, while the quick two-second closing action ensures rapid shutoff in emergency or power failure conditions. The valve is compatible with natural, propane, and manufactured gases and is widely used in furnaces, boilers, and industrial combustion systems. Key Features: Normally Closed Safety Design: Ensures automatic gas shutoff when power is lost or system failure occurs. High Flow Capacity: Handles up to 2400 CFH for large industrial and commercial gas systems. Fast Response Time: Closes within two seconds for enhanced system safety. Line Voltage Operation: Runs directly on 120V AC power for easy integration with control systems. Adjustable Opening Rate: Configurable using bleed valve or fixed orifices to suit burner requirements. Durable Cast Aluminum Construction: Lightweight yet strong, providing long-lasting reliability. Wide Gas Compatibility: Supports natural gas, propane, and manufactured gas fuels. Horizontal Mount Design: Simplifies installation in standard gas lines. Temperature Resilience: Operates effectively between 32°F and 125°F. Optional Position Indicator: Allows for visual confirmation of valve status during operation. The V48A2185 delivers the reliability and precision required for critical gas shutoff applications, ensuring safe, efficient control in industrial and commercial burner systems.
