Universal Arma-Gard™

Two-way Universal Arma-Gard™ (DSC-AGS*2WS) (DSC-AGS*2WD)

Single installation for positive and negative pressure protection

Two-way Universal Arma-Gard™ is an engineered graphite rupture disc device designed to prevent vessel damage from under vacuum or over pressure conditions. Unlike standard rupture discs, this two-way acting bursting disc is designed to be installed directly between flanges. Due to its assembly, this rupture disc offers you reliability and peace of mind being the only two-way functioning graphite rupture disc to be used with ATEX-approved, reusable burst detection Flo-Tel™ .

Two-Way Arma-Gard offers unique benefits over traditional graphite discs

Two-way Arma-Gard benefits from a unique 10% tolerance with an 85% operating to burst pressure ratio. This graphite bursting disc requires no holder to fit directly between flanges and is non-torque sensitive due to its stainless steel armoured ring, allowing for the degree of clampage necessary for correct sealing. This disc provides excellent corrosion resistance and is suitable for very low burst pressure applications

Simple installation between industry standard flanges

Two-way Arma-Gard acts as a single disc installation for both positive and negative pressure protection. Due to its unique construction Universal Arma-Gard offers ease of installation between industry standard flanges. This graphite rupture disc overcomes problems associated with traditional graphite discs and is not directly affected by over-torquing or easily damaged during storage or installation.

Cutting costs on rewiring

Two-way Arma-Gard is supplied as standard with the Elfab Flo-Tel actuator to allow for use of Elfab’s unique, reusable, non-invasive burst detectionsystem Flo-Tel™ . Due to its assembly, this disc offers you stability and peace of mind with its integrated detection attached allowing you to instantly know when the disc has ruptured.
