Abstract
A button-operated main shut-off and flow-control valve is disclosed which attaches directly to a supply cylinder in place of the conventional rotary-stem shut-off valve. Magnetic actuators in the valve eliminate the hazards of leaky seals around moving or rotating parts. Excess flow control is provided by internal valve elements which inhibit further fluid flow in excess of a design limit, and pressure regulation is provided within the same housing so that extremely low profile is preserved and fluid connections are significantly reduced for improved operating safety.
