GX1 High Pressure Valve | Electronic Pressure Regulator

The GX1 high pressure valve is a complete re-design of Proportion-Air’s successful GP product. With this re-design we greatly improved the accuracy, resolution and repeatability of our high pressure control valve. The GX1 high pressure valve is 50% less weight (with non O2 cleaned GX) than the GP. The GX1 can also be used to pilot a volume booster and achieve much higher flows with the same great accuracy.

The GX1 high pressure valve has several other unique and beneficial features. An on-board split power supply allows true zero for command and monitor even though the GX is powered by a conventional single ended power supply. The GX1 utilizes advanced on board power management hardware to minimize current draw and heat build up. The GX1 also features status indicating LEDs for power and TTL. The TTL signal is a conditional on/off signal to use for diagnostic purposes. This signal is LOW when the pressure is within 1% of final setting.

The GX series can be paired with a variety of high pressure volume boosters for even greater flow. When using a volume booster, the GX2 can be used to achieve accuracy similar to the GX1.
