A202 |
• Adjustable pressure limit
For liquids, gases and steam
• Overpressure up to 400 bar
• Temperature up to 180 °C
Protection of pressure gauges and pressure transmitters against overpressure.
The A202 is designed to protect an instrument from damage caused by overpressure, exceeding the measurement range.
A valve closes automatically at the preset value, avoiding the circulation of the fluid towards the instrument.
When the pressure drops back 25% below the preset value, the valve opens and restore the circulation of the fluid.
The pressure relief valve is usually mounted between the instrument and a gauge separator.
