LZ225 Low Power Latching Solenoid Valve for Fire Protection, 6V Lithium Manganese Battery Driven

LZ225 Series Latching Solenoid Valve Product Introduction

The SENYA LZ225 series 2/2-way pilot-operated latching solenoid valve is engineered with exclusive self-holding magnetic structure, fundamentally solving the high power consumption and short service life pain points of traditional continuous energized solenoid valves. Unlike ordinary valves that require sustained power supply to maintain open or closed status, this latching model only needs a short reverse polarity pulse of over 50ms to complete state switching, and fully cuts off power after action while locking the valve position stably relying on built-in permanent magnet force. It achieves zero standby power consumption, with instantaneous power only 3.5–4W during the brief triggering pulse, delivering ultra-low energy consumption performance perfectly matching battery-powered fire suppression equipment. The intermittent power supply design drastically reduces continuous heat generation of the coil, eliminating insulation aging and burnout risks caused by long-term heating, which greatly extends the overall service life of coils and valve bodies for long-term unattended operation.

This series supports diversified DC voltage options including DC6V, DC12V and DC24V, fully compatible with 6V lithium manganese batteries, common control cabinets and standard industrial DC control systems. The polarity control logic is clear: positive wiring to the left coil pin opens the valve, reversed positive-negative wiring closes the valve, and both flying lead cable and DIN43650 standard connector wiring types are available for flexible on-site wiring. The valve body provides rich port specifications ranging from 1/4" to 2" BSPP/NPT thread, with two material options: brass body (LZ model) and SUS304 stainless steel body (SLZ model), adapting to diverse fluid mediums including air, water and oil with viscosity below 30 CST. Three sealing materials (NBR, EPDM, FKM) cover operating temperatures from -10℃ to 150℃, while the working pressure range of 0–16 bar and maximum pressure resistance of 20 bar satisfy most fire protection fluid control demands. The optimized flow channel design delivers stable CV values from 0.23 to 48 across all sizes, balancing fast response and smooth medium circulation.

Targeted primarily at energy storage fire suppression and general fire protection systems, the LZ225 latching solenoid valve stands out as the optimal fluid control component for battery-driven fire cabinets, remote monitoring fire equipment and off-grid fire facilities. Its biggest competitive edge lies in outstanding battery adaptability: since power is only consumed during transient switching, the service life of 6V lithium manganese batteries can be maximized without frequent replacement, lowering post-operation maintenance costs significantly for unmanned fire equipment deployed in data center energy storage cabinets, new energy power stations and remote industrial workshops. Conventional solenoid valves drain battery power nonstop and generate sustained heat, leading to frequent battery depletion and coil failure; the LZ225 series erases these hidden safety hazards, delivering higher stability and reliability for long-cycle fire protection standby scenarios.

Strict structural and dimensional standardization ensures convenient installation and batch replacement. Complete dimension drawings and unified ordering coding system simplify procurement and engineering matching, with customizable combinations of port size, voltage, seal material, connector type and thread standard to meet customized fire system requirements. The pilot-operated structure guarantees reliable switching under low initial pressure (0.5 bar for 1/2"–2" models), avoiding valve malfunction caused by unstable pipeline pressure in fire pipelines. All products undergo strict pulse switching cycle testing to verify stable latching performance after millions of repeated actions, with no valve position drift or failure under long-term power-off standby. Beyond fire suppression, this low-power latching valve also applies to water treatment, gas control and remote fluid control devices with limited power supply. Combining ultra-low energy consumption, long service life, wide media & temperature compatibility and flexible battery drive compatibility, the SENYA LZ225 series becomes a cost-effective, high-durability fluid control solution specially tailored for modern energy storage and fire protection industries.
