Applications of Monoflange Valve
- Instrumentation: Monoflanges are ideal for mounting pressure gauges, transmitters, and other instruments. Their compact design eliminates multiple fittings and reduces potential leak points, saving space.
- Process Isolation: They are used to isolate instruments from the process fluid for maintenance or calibration. The block and bleed functionality allows venting any trapped pressure before removing the instrument.
- Pressure Relief: Some monoflange designs incorporate a pressure relief valve. This safety feature protects the instrument from overpressure situations.
- Flow Control: Certain monoflange valves include an integral needle valve for regulating flow. This allows for fine-tuning the flow rate to the instrument.
- Corrosion Resistance: Monoflanges can be constructed from various corrosion-resistant materials, like stainless steel or exotic alloys. This makes them suitable for harsh chemical environments.
