air release valvesAir Release (Venting) Valves AR SeriesAir Release (venting) Valve allow gases to escape from un pressurized pipe lines. As the un pressurized air vents, liquid rises to the float (an inverted cup), which lifts the float up against the seat, holding liquid pressure. The float will not release until the pressure on the inlet side of the valve is equal to the outlet pressure of the valve (normally atmospheric).

gauge isolator SG Series Gauge Isolators Gauge Isolators SG Series Gauge Isolators allow inexpensive pressure gauges, or any other pressure instrument to be used in corrosive services. The upper chamber (gauge side) is filled with a stable fluid such as glycerine‡. A diaphragm separates it from the lower chamber which receives the media under pressure. The 1/2" gauge connection allows use of the popular 4" and 4-1/2" diameter gauges.
