SPECIAL VALVE DESIGNS

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
