Oseco

Pro-S sanitary pressure-relief system
The Pro-S sanitary pressure-relief system features a reverse-buckling rupture disc whose smooth side faces the product flow to minimize product build-up and blockage. The disc is precision-scored on the vent side to burst in the event of over-pressurization. The Pro-S system includes the Oseco Sanitary Sensor (OSS), which indicates when the disc has ruptured and can be used to activate a variety of alarms, including computer-controlled systems. This disc requires no special liners or coatings and is designed to operate at up to 90% of its burst pressure in hygienic environments. It is available with burst pressures as low as 16 psig.

GLV-F explosion vent
The GLV-F explosion vent can be mounted on conveyors and grain elevators where dust builds up. During an explosion, it opens to release pressure and minimize damage. It has a built-in outlet frame and gasket that eliminate the need to fabricate an angle-iron hold-down frame, making it easy to install. It meets the requirements of National Fire Protection Association (NFPA) 61 for the prevention of fires and dust explosions in agricultural and food-processing facilities. It is available with an alarm sensor for automatic system shutdown after an explosion.

Deltaflow switchover valves
Deltaflow switchover valves allow customers to use dual relief devices to eliminate process shutdowns. In this way, if a disk on one side of the valve breaks, a reserve disk can be placed into service immediately by actuating the valve. The ruptured disk can then be replaced without shutting down the system.

Product Catalog
This company’s new full-color catalog offers information about its full line of pressure relief devices. Comprehensive descriptions and technical specifications are given for the firm’s rupture disks, rupture disk holders, sanitary products, rupture panels, single-use assemblies, alarms and sensors. Easy-to-read charts display burst pressure tolerance, panel-specification information, and temperature-limit data. New this year is information offered not only in psi, but also in barg.

Pro+ rupture disk
Pressure relief systems have the lowest pressure drop and the highest flow when the rupture disk with the lowest KR (a rating given by ASME) is used. The Pro+ rupture disk has earned the lowest currently registered KR rating for a reverse-buckling disk family, 0.29, making it one of the most effective pressure relief devices on the market and earning it a UD ASME authorized stamp. The disk’s 95% operating ratio guards against fatigue and premature disk rupture in applications with high operating-to-set ratios. Burst pressures from 8 to 750 psig ensure consistent performance in a wide range of uses from high- to low-pressure environments, with long service life even in high-cycling applications. The one-piece design is scored on the vent side to prevent product buildup.

S-PRO-S
The S-PRO-S combines a bursting disk and sensor into a single assembly, eliminating additional tri-clamp ferrules needed to install a separate sensor. When the disk bursts, the sensor’s circuit is broken, triggering activation of an alarm. With quick alarm detection, bursting disks can be replaced and overpressure situations corrected with a minimum of process downtime. The S-PRO-S is ideal for use in sanitary services. Placement of the sensor and disk scoring on the vent side present a smooth surface to the process, minimizing product build up. A non-fragmenting design prevents contamination from rupture disk pieces entering the process after bursting. The uni-body system is able to withstand full vacuum (14.7 psi) without a separate vacuum support. Available in a wide range of sizes from 1 in. to 4 in., the S-PRO-S sensor and disk are wellsuited for applications in a broad range of burst pressures (from 16 to 150 psig).
