No damage due to pressure fluctuations and unwanted pressure increases with the innovative REDisc overpressure valve.
Solution for processes where even the smallest pressure fluctuations are undesirable:
- Can be used as often as required, more efficient than bursting discs
- Low response pressure, also adaptable to individual process conditions on request
The REDisc overpressure valve meets the highest safety and reliability requirements and is versatile – for example in isolators.
We guarantee safety.
Thanks to the low response pressure below 0.1 bar, the REDisc valve is not a classic safety valve in the sense of the Pressure Equipment Directive 2014/68 EU and therefore does not fall within the scope of ISO 4126-1. Nevertheless, we fulfil the requirements of this product standard as far as applicable to our product.

How the overpressure valve REDisc works.
REDisc is available in several versions, but the functional principle is always the same. In the REDisc version, you can check the 100 % tightness at any time by means of a hand pump with pressure gauge. Test pressure is built up via a test groove milled into the housing.
In the resting state, the closing body is in the closed position. The valve is closed and tight. In normal operation and below the defined opening pressure, the closing body remains in the closed position.
In case of overpressure, the pressure pushes the closing body into the open position. This allows the excess pressure to escape. When the pressure drops again, the valve closes by itself.
