Storm 3000100 Normally Closed Brass Master Valve 1 Inch

Product Description

The STORM 3000100 is a 1-inch normally closed brass master valve designed for automatic shutoff applications in irrigation and fluid control systems. In its de-energized state, the valve remains closed, making it a reliable choice for fail-safe water management. The brass body provides corrosion resistance and durability in both residential and light commercial installations. Licensed irrigators and plumbing professionals install this valve as the primary control point on a mainline to prevent unintended flow when the system is not actively commanded to run.

This valve is suited for use as a master or zone shutoff in underground irrigation systems, landscape water management setups, and similar low-pressure fluid distribution lines. The 1-inch port size accommodates standard mainline piping found in most residential and light commercial irrigation layouts. It is typically installed upstream of zone valves to provide an additional layer of system-level control and backflow protection.

Key Features

• Normally closed design ensures the valve defaults to a closed position when de-energized, supporting fail-safe operation
• Brass body construction offers corrosion resistance and long service life in buried or exposed installations
• 1-inch port size compatible with standard mainline irrigation piping
• Functions as a master shutoff to cut system-wide water flow when irrigation zones are not active

Compatibility

Designed as an OEM-style replacement or direct-install master valve for 1-inch mainline irrigation and fluid control systems.

Installation Notes

Installation should be performed by a licensed irrigator or qualified plumbing professional in accordance with local codes and IPC guidelines. Shut off the main water supply and relieve system pressure before making any connections. Ensure correct flow-direction orientation as marked on the valve body before completing the installation. Verify that the control wire voltage matches the valve solenoid rating before energizing the system.
