Single disk design covers 95% of plant requirements

Scoreless design offers higher cycle life when compared to scored reverse acting disks

Low and high burst pressures available in a single design

Excels in liquid or gas applications

0% manufacturing range is standard

Operates to 90% of the disk's rated burst pressure

Non-fragmenting design

Excellent for isolating safety relief valves

Damage ratio of 1.0 or less

Resists product buildup.  Only the smooth side of the disk is exposed to the process medium

Additional TFE corrosion protection available (specify URA-L)

3-dimensional tag

ASME UD stamping available

Forward-acting, tension-loaded design, with laser cut metal cap, metal or TFE seal

Operates to 80% of the disk's marked burst pressure

Sizes 1/2" thru 24" diameters

Burst ratings range from 3 to 2,500 PSIG

Temperature ratings up to 900°F (482°C)

Suitable for liquid, gas, or 2-phase flow

3-dimensional tag

UD stamping available

Forward-acting, tension-loaded design without score lines

Standard 30° angle seat design

Burst ratings 5 to 50,000 PSIG

Operating pressures to 70% of the disk's marked burst pressure

Sizes 1/4" thru 24" diameters

Temperature ratings up to 900°F (482°C)

Suitable for liquid, gas, or 2-phase flow

3-dimensional tag

UD stamping available

Solid metal scored disk

Operating pressures to 85% of burst rating

Non-fragmenting design is suitable for liquid, gas, or 2-phase flow

Scored after disk material is formed to a high crown height.  Permits use of thicker material and allows lower ratings to withstand full vacuum

Burst ratings 30 to 1,800 PSIG

Sizes 1/2" thru 20" diameters

Temperature ratings up to 900°F (482°C)

Materials of construction:  316SS, Inconel, Monel, nickel, or aluminum

UD stamping available
