Overview
This three stage pressure relief valve is a
balanced piston type pilot operated relief
valve integrating three pilot relief valves and
one solenoid operated directional valve into
one body, and can control the circuit pressure
at two or three stages with electrical signals
to the solenoid operated directional valve.
Type indication
Features
1. The circuit pressure can be controlled at
two or three stages without vent
connection.
2. Concurrent use of the shock damping
valve (refer to the section of the type
number index “ZNS5”) can perform
shockless, smooth pressure change.
3. Adoption of the unequal type for the main
plunger has realized stable operation.
