Dynisco Introduces New Line of Rupture Disks for Extrusion Applications

Franklin, MA (March 12, 2007) . . . Dynisco has introduced a new line of rupture disks designed to provide emergency relief of excess pressure build-up in a system. Also known as "burst plugs", these products instantaneously rupture at a specific predetermined pressure range.

Designed for use in extrusion applications, these products can be used for primary relief in applications where pressure build-up can occur so rapidly that the response time of a relief valve is inadequate.

"These products provide low cost insurance against the safety hazards and damage of a potentially catastrophic pressure burst," said Matt Carrara, Dynisco Vice President of Sales & Marketing. "We have seen great demand for these products, so we've expanded our product line to cover a wider range of pressures, and to work with a wide variety of process connections."

Key features of Dynisco rupture disks include:
-available for burst pressures from 1,500 to 15,000 psi
-simple, intrinsically safe design
-up to 750° F melt temperatures standard
-accuracy of ±5%

The expanded line is now available with the following process connections:
-US industry standard 1/2-20 UNF mounting thread with lengths of 1.81", 3", 6", 9", and 12"
-1/2-20 UNF mounting thread with a ¼" NPT fitting for polymer discharge
-European industry standard M18 x 1.5 mounting thread
-5/8 - 11 NC mounting thread
-3/4 - 16 UNF mounting thread
