BARL special valve designs are used under conditions that are not entirely the everyday type.
- For system and/or differential pressure
- At high switching frequencies
- At high temperatures
- Required pressure surge resilience
Due to the great number of possible executions, we have dispensed with specification of further types.
The following are illustrated:
- High-temperature sliders
- Needle sliders for shutting off large bulk material grains of 20 – 100 mm. They are used as repair sliders
- Double flat sliders
