Pressure relief devices for transformers

Within the family of pressureregulating valves, a technical distinction is made between series of bypass valves, inline valves and threeway valves.

The pressure relief valves GEMÜ N085 and N185 protect the plant and the piping system against gauge pressure and reduces pressure peaks. The third pipe spigot enables the valve to be installed in the main pipe. If the pressure increases, the spring is raised and the valve opens. The pressure is reduced to the preset value and can escape via the third pipe spigot into an adjacent pipe. If the pressure falls, the spring force presses the diaphragm in the direction of the seal seat and it is closed. The spring force can be adjusted as required using a set screw. - Valve adjustments can also be made under working pressure. - The optimization of piston, springs and control face ensures good control characteristics - The actuator is hermetically separated from the medium

"Our stock consists of about 40 transformers (low and high voltage) up to 3MVA that can be rented or sold. We find power transformers in different types of applications: in electrical transmission networks, in electrical distribution and in factories."

Our mid range frequency converters are delivering up to 250 kW output at frequencies down to 4 kHz. For high frequencies up to 2 MHz we have our high frequency converter series HU.
