Leak Defense System (LDS) - Dual NPT - LDS-3-D

Dual (Hot & Cold) Flow-Based Leak Detection

Features

• Automatic or manual water shutoff valve with advanced, non-mechanical flow-sensing technology
• Custom proprietary sensor with control PCB internal to actuator
• Full-port lead-free brass ball valve with stainless steel probe pipe
• Various alarm and alert types (See Controllers)
• Shut off a single valve or an entire zone with one touch
• Requires LDS-3-WCP or CCM to interact with the valve
