§01

The mission, in three lines.

Built around one promise: when something goes wrong, the gas goes off.

01

Safety
First.

Automatically shuts off gas during earthquakes and fires — preventing catastrophic damage and saving lives.

02

Solid-State
Tech.

No moving sensor parts to wear out. Solid-state electronics deliver the reliability you need when you need it most.

03

Easy
Install.

Engineered for clean integration into existing gas line infrastructure by professional plumbers and contractors.

§02

Two emergencies.
One valve.

Most valves do one job. California Smart Valve handles both — in a single device, on a single install.

Threat 01 — Seismic

When the ground moves,
the gas stops.

Internal seismic sensors trigger an immediate shutoff during earthquakes — closing the gas line before a ruptured pipe can find a spark.

  • Solid-state seismic detection
  • Instant mechanical shutoff
  • Manual reset after the all-clear
Threat 02 — Fire

When the heat rises,
the gas stops.

A fire-emergency response system shuts off gas supply when temperatures spike — cutting fuel from the fire before it reaches the line.

  • Thermal trigger built in
  • Closed-loop electronic shutoff
  • No external power required

FIRST OF ITS KIND First valve to combine seismic detection and fire response in a single, easy-to-install device.

§03

The device.

A solid-state, dual-protection gas safety valve. Engineered, patented, manufactured in California.
