The 94200 is available with low base for liquid overflow. When specified, elongated guides and special stops can be provided to limit pallet lift. The pallet guide is deep enough to assure proper reseating of pallet after pressure relieving at lower overpressures. Pallet will reseat when tank pressure drops below set pressure.
For tank venting or examination, the pallet may be removed off its base offering a clear unobstructed passage. A retaining cable is provided to fasten the pallet to the base.
