Type SRX - Reverse Acting Scored

Description
The Fike SRX bursting discs are reverse-acting, compressionloaded, and scored with an X-pattern to facilitate opening without knifeblades. The concept of ‘reverse-acting’ means that the disc is installed with the crown in the direction of the process side. Once reversal pressure is achieved, the crown of the disc is reversed from the inlet side of the assembly to the outlet side. The preweakened scoreline facilitates the full opening of the disc.
Due to the high flow coefficient, the high operating ratio of 95%, and the backpressure resistance, the SRX bursting discs are mainly used for relief valve isolation.
The SRX bursting discs are available in a wide range of materials and can isolate the relief valve from the corrosive action of the process, so that the valve can be constructed from less expensive materials.
