Webster-Wilkinson Ltd manufactures and supplies the following transformer protective devices

Pressure Relief Devices
These simple spring operated devices are pre-set to a release pressure specified by the user. Our normal range is from 0.2 bar to 0.7 bar in 0.05 bar intervals. The device is designed to automatically re-set after operation. The device screws into a 1” BSP boss normally welded onto a transformer tank cover. We are also able to supply this boss if required.
