TIVAL mechanical pressure switch FF 4 DRH

TIVAL FF4 DRH pressure switch - with manual reset function for maximum safety

The TIVAL FF4 DRH is a precise mechanical pressure switch with perbunan diaphragm and silumin pressure connection, designed for pressure ranges from 0.11 to 32 bar. It impresses with a large connection chamber, simple adjustment, an easy-to-read scale and high repeat accuracy. The pressure connection H (G 3/8″ internal thread, DIN 1725/2) made of ALSi 12 ensures stability and durability in industrial use. The DRH version has a manual reset function: if the pressure rises above the set value, contact 1-2 opens, closes 1-4 and locks. If the pressure falls below the set value, the contact can be manually unlocked using the reset button - for additional operational safety in critical pressure applications. The FF4 DRH complies with the standards VDE 0660, IEC 337-1 and IEC 553-1
