CEDASPE® VP150-QT/VP150-ST (former ETI VQT/VST)

Pressure relief valve size 150 for power transformers (with contacts) and with complete oil tight cover

CEDASPE® VP-150 QT have been specially designed for use on transformers where no external pollution is admitted. It opens when the pressure inside tank increases over the set value, and reduces the pressure in the tank by releasing oil. The oil-tight cover contains the oil released by the valve and provides a flanged connection on which a pipe can be attached that ducts the oil in the desired direction. A draining screw allows to remove the oil inside the flanged cover before removal during maintenance operations.
