PRO
PRECISION REVERSE-OPERATING RUPTURE DISK
The PRO disk is Osecoís latest pressure relief innovation. It brings our high-performance reverse-operating disk technology to a new level of low-pressure reliability. The PRO features low burst pressures in a single-membrane configuration, due to its precision scoring utilizing Osecoís unique computerized load cell technology. The PRO operates at up to 90% of its burst pressure and is highly recommended for either liquid or vapor processes. It is nonfragmenting and not torque-sensitive, and standard materials of construction include Hastelloy® C-276, stainless steel 316, nickel, Monel®, and Inconel®. Please contact the Oseco factory for sizes, materials, temperatures, or configurations not listed below.
