Pressure Relief Vent G442
The Pressure Relief Vent G442 is a safety component for controlled pressure relief at exhaust openings of venting lines in gas plants and systems, including use in potentially explosive atmospheres.
Its weather-protected design prevents the ingress of rain, snow, and other precipitation, ensuring safe and reliable outdoor operation.
For reduced noise emissions during venting, the G442 can be combined with Glaunach silencers, making it suitable for noise-sensitive and safety-critical environments.
The optimized flow design ensures rapid dilution with ambient air, reduced noise levels due to low-turbulence flow, and protection against rain ingress. Custom sizes are available upon request, designed in accordance with DVGW G 442.
* Standard blow-off devices in accordance with DVGW Code of Practice G 442.
This design is the preferred option.
The G442 Vent is manufactured from stainless steel
and is optionally available with an integrated bird screen.
A wide range of customised connection options is available, including threaded, clamp-type, welded, or flanged connections.
