LO-V Brochure

The Fike Lo-V is a bi-directional rupture disc that is designed to relieve undesired pressure conditions in two different directions. Certain types of applications, such as storage tanks, need protection from vacuum pressure as well as from potential overpressure. The primary relief can be via the reverse-buckling section, which is typically extremely low vacuum pressure, or the higher pressure-activated, forward-acting section. Depending on how the holder is oriented, the Lo-V can perform the tasks of two different rupture discs!

The SHX rupture disc is a forward acting, cross scored rupture disc, ideal for high pressure sanitary applications. The concave surface of the SHX rupture disc remains in contact with the process media and is designed to burst along the cross score pattern when subjected to a predetermined pressure. In addition, the hub ring prevents the disc petals from fragmenting at the maximum burst pressure and provides a rigid support to prevent the disc from slipping.

Features and Benefits

* Operating ratio of up to 90% without premature failure due to metal fatigue
* Superior design for CIP/SIP requirements. The gasket design creates proper alignment with the inside diameter, or bore, of the ferrule/fittings.
* Integral replaceable gaskets create ease of installation; offered in a variety of 3-A up USP Class VI approved materials: White silicone (pt cured), Viton, white and black EPDM, Teflon and J-1500
* Teflon liner option available on the process side of the rupture disc
* Standard sanitary packaging includes sanitary discs poly-bagged, nitrogen purged and sealed.
* Damage ratio of ? 1
* When assembled in accordance with the SHX Installation and Maintenance Instructions, the SHX will withstand a helium leak rate of a minimum of 1 x 10-4 atm cc/sec (bubble tight)
* 316 SST tag visually confirms proper installation and orientation
* Constructed of 316/316L SST
* Average surface finish of wetted surfaces:
     Standard: 12-25 Ra
     Electro-polished: 8-16 Ra
* Temperature limit: 250°F (121°C) (consult factory for higher temperatures)
