SYMBOL
DESCRIPTION
Threaded cartridge, pilot-operated, pressure-reducing/relief valve with variable input for continuous adjustment within specified range. The output pressure is proportional to the DC current input. The valve may be used as a pressure limiting device in the apparatus.
OPERATION
When there is no current in the coil, ZY-TS80-30 allows oil to flow freely from ① to oil port ③. When the coil is energized, ② will be connected to ①. The control (decompression) pressure will increase proportionally with increasing current in the coil. If the pressure at ① exceeds the set value generated by the coil, the overflow from ① to ③ is injected: the back pressure of oil port ③ will be added to the pressure set value.
FEATURES
* 12 and 24 volt coils standard.
* Optional E-Coils, waterproof and IP69K compliant.
* Industry common cavity.
* Deflation criteria.
