The Gasline 309 is a gas ball valve with a unique built-in pressure port downstream of the ball that allows for pressure tests with the ball only in the close position. The positioning of the prssure port is a deliberate safety feature. The handle must be in the full closed position to access the pressure port.


The VRN3000 TAE is a gas safety ball valves with an additional thermally activated mechanism that shuts off gas flow regardless of the ball orientation. The thermal activation occurs at 92°C to 100°C (197°F to 212°F) and will maintain shut off up to 925°C (1697°F).
