Leading rupture disk manufacturer Oseco has launched its new PRO+ (precision reverse operating) rupture disk. The PRO+ disk features a 95% operating ratio to guard against fatigue and premature disk rupture in demanding pressure applications for both gas and liquid services. It is the only 95% operating ratio disk on the market that operates without the use of cutting teeth. This one-piece design and smooth surface to the process prevent product buildup. With burst pressures from 8 to 750 psig, the PRO+ is compatible with a broad range of applications, performing consistently in both high and low pressure environments.Oseco.
