ARCHON's series 900 gauge cocks have drop forged steel bodies with stainless steel trim, a threaded renewable seat, union bonnet and safety ball checks allowing the flow to automatically shut off, should the glass break. The ball may be omitted upon request. The 900 series gauge cocks are quick closing and are equipped with backseating stems to allow repacking while under pressure. This backs out the stem to its limit so the knob on the end of the stem seats against the sleeve which stops fluid from reaching the packing. Various connection styles are available to accommodate most pipe requirements.

The special offset feature was designed to allow easy cleaning of the inside of the gauge. The drain and vent connections are directly aligned with the gauge chamber and are offset 7/8" from the center line of the vessel connection. It is possible to clean the inside of an end connected gauge through the drain and vent connections without removing the gauge from service.

The union gauge connections make it possible to turn the gauge to any desired angle for the most convenient visibility. The union vessel connections provide access to the ball check. Gauge cocks are typically furnished with handwheel operation, but can also be supplied with a lever.
