SAFETY SYSTEMS Type ECR Reverse Bucklin Compression Loaded Disk

Eco-Saf® System Eco-Saf™ (type ECR) reverse buckling compression loaded style disk provides overpressure relief in either gas / vapor or liquid applications. The ECR disk is designed with a perforated circular score in the perimeter of the dome. Gaskets which are activated by assembly of the safety head, cover the perforated score line to achieve a sealed construction. The snap action of reverse buckling disk technology enables very low burst pressures to be achieved avoiding the use of weaker slotted composite disk designs. At the disk’s burst pressure, the disk reverses, opening along...

If a type ECR disk is accidentally damaged before or during installation, the disk will burst providing full relief opening at a pressure not exceeding its tagged burst pressure. The disks are supplied with gaskets attached to both sides of the disk. Temperature range Three types of sensors can be used with the ECO disk (EC-BAS, EC-SAS or EC-MBS). Leak Tightness Disk type Inlet gasket Burst pressure Leak rate Viton® (black) Silicone EPDM (black) Rules for Selecting Gaskets (Standard Designs) • There is a minimum of two gaskets per disk. At least one gasket must be elastomeric (Buna, Viton,...

Safety Heads EC-7RS Safety Head The ECR disk is installed in the EC-7RS safety head and the capscrews torqued to provide the correct load on the disk in the workshop before installation into the process. The pretorqueable feature minimizes the possibility of process leakage or premature disk failure due to incorrect torque. Asymmetric locating pins centers the disk in the safety head ensuring direction of disk installation.. Application of the correct integral cap screw torque activates the disk integral gasket to achieve a bubble tight construction. The EC-7RS is designed with a unique...

Asymmetric locating pins center the disk in the safety head, and ensure correct direction of disk installation. On installation of the safety head and disk assembly between pipe flanges, application of the correct torque to the flange bolts activates the disk’s gasket to achieve a seal. The EC-7R is designed with a metal-to-metal stop preventing overtorquing and consequential damage to the disk. F low arrows indicate the direction of flow during process venting. When the disk ruptures, the petal is fully contained within the outlet of the spool design EC-7R. This eliminates...
