The Shand & Jurs 94200 Emergency Vent and Manhole Cover from L&J Technologies is designed for liquid storage tank applications where emergency pressure relief and tank access are required in a single assembly.
This product supports emergency venting by relieving excessive internal tank pressure, helping reduce the risk of tank roof damage during overpressure conditions.
It also functions as a manhole cover, allowing access for tank examination or venting when the pallet is removed.
The 94200 is available in multiple manhole opening sizes and connection styles to support a range of tank configurations. The design includes a removable pallet that provides a clear passage when tank access is needed. A retaining cable secures the pallet to the base, helping simplify handling during inspection or maintenance activity. The pallet guide is designed to support reseating after pressure relief once tank pressure drops below the set pressure.
This emergency vent and manhole cover may be specified with options such as a low base for liquid overflow, elongated guides, and special stops to limit pallet lift.
Available material options include aluminum, steel, and 316 stainless-steel. ATEX certification for hazardous locations and CE certification for ordinary locations are available when specified.
