Reverse Arch with Slotted Rupture Disk (YC)

Fragment-free design

Size range: 15mm-250mm

Burst pressure range: 2.5 barg-195 barg

Can be operated at up to 90% of the nominal burst pressure without exceeding the maximum allowable working pressure of the unit.

Can withstand full vacuum without the need for a backing bracket

For use with gaseous media

Good fatigue resistance

Smooth, convex surfaces contact the media, preventing media buildup

Can be used in series with safety valves

Standard materials available, special materials can be customized

Reverse Arch with Slotted Rupture Disk (YC)

Product Overview

Reverse arch rupture disks with the convex side on the high side of the pressure system. Reverse arch with slot rupture disks, which are opened by the destabilizing flip of the rupture disk, following a preformed, engraved slot to relieve pressure.


Options

Fluoroplastic lined or coated
BI Burst Sensor
Note: Lining and BI have a lower temperature resistance than the Strength Membrane.


Safety Valve Protection

When rupture disks are installed under the safety valve, they isolate the valve's working parts from corrosive media.
Relief components: gauges, tees, relief valves, tubing


Burst tolerance / (GB567-2012)


Calibrated burst pressure
bar
≥0.01~<0.1 ≥0.1~<1 ≥1~<3 ≥3~<1000 ≥1000~<5000
Bursting Tolerance ±50% ±25% ±0.015MPa ±5% ±4%
* The rupture tolerance is the maximum expected change in rupture pressure marked by the rupture disc.
