It is designed to relieve excessive internal pressure in liquid storage tanks while providing excellent protection against costly tank roof rupture repair. The Expanda-Seal™ design also decreases product leakage below actual set point. The standard design is available in 20″ & 24″ flange.
The Model 94201 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 relief at lower overpressures. Pallet will reseat when tank pressure drops below set pressure.
For tank venting or examination, the pallet may be removed from its base offering a clear unobstructed passage. A retaining cable is provided to attach the pallet to the base.
