Galley Maid SV-1 12VDC High Pressure Solenoid Valve — Reliable Automatic Shutoff for Propane and LPG Gas Systems
The Galley Maid SV-1 is a heavy-duty, high-pressure solenoid valve designed specifically for use with liquefied petroleum gas (LPG) and propane systems. Operating on 12 volts DC, this normally closed valve opens when electrical power is applied and automatically shuts off the moment power is removed or interrupted — a critical safety function for any pressurized gas installation. Rated for pressures from 0 to 312 PSI, the SV-1 handles the full range of pressure found on the high-pressure (tank) side of a standard LPG regulator. It connects with 1/4" male tapered pipe thread on the inlet and 1/4" female tapered pipe thread on the outlet, making integration into existing propane supply lines clean and straightforward.
What makes the SV-1 a trusted choice is its fail-safe design. Because it defaults to the closed position when de-energized, there's no risk of gas flow continuing during a power loss, a blown fuse, or a system fault — exactly the kind of behavior you want from a gas safety device. It is UL listed, confirming it meets recognized safety standards for electrical and gas control equipment. Whether it's installed in a propane locker on a vessel, an RV, a cabin, or a commercial kitchen setup, the SV-1 gives users the ability to control propane flow remotely from a switch panel without having to physically access the tank itself. The kit includes a 3/8" male flare x 1/4" female NPT brass fitting for easy connection to standard supply line hoses.

Frequently Asked Questions
Q: Does this solenoid valve need to stay powered for gas to flow?
Yes. The SV-1 is a normally closed valve, which means gas only flows when 12VDC power is actively applied. If power is cut for any reason — intentionally or due to a fault — the valve closes automatically, stopping all gas flow.
Q: Can the SV-1 be used for both propane (LPG) and CNG (compressed natural gas)?
Yes, the SV-1 is compatible with both fuels. For propane, it should be installed on the high-pressure side of the regulator, between the tank and the regulator. For CNG, it is installed on the low-pressure outlet side of the regulator.
Q: Is the SV-1 compatible with remote switch panels and gas fume detectors?
Yes. The SV-1 is designed to work with the C-1 solenoid control panel and is also compatible with S-1A and S-2A gas fume detectors, making it easy to build an integrated gas safety and control system.
Q: What fittings are needed to connect the SV-1 to a standard propane supply line?
The valve uses 1/4" tapered pipe thread connections. The included kit accessory is a 3/8" male flare x 1/4" female NPT brass fitting, which allows direct connection to the common 3/8" female flare supply line hoses used with standard propane appliances.
Q: Is there a manual override if electrical power is unavailable?
The SV-1 does not include a built-in manual override. If power is unavailable, the valve will remain in the closed (safe) position. To restore gas flow, electrical power to the valve must be reestablished.
