EMC 2L-45-01
MAIER 3 01 K


Product description

Designed to prevent damage to the tanks of oil-filled transformers if the internal pressure suddenly rises above the permissible level.

Operating principle

The valve springs press the valve against the body. The housing is mounted on the tank.

The pressure created by the transformer oil acts on the valve in the other direction, counteracting the springs. When the force of the oil acting on the valve exceeds the force of the springs – the valve opens. When the oil force decreases, the valve closes.


  • Response pressure – 20 to 75 kPa.
  • The nominal bore diameter is 12 mm.
