- Porting Pattern: Complies to ISO 4401-03-02-0-05 standards and can be provided with or without locating hole.
- Pressure Ratings: This allows multiple pressure settings to be selected for use in various applications.
- Directions of Action: Can be configured with any one of five optional directions of action.
- Pressure Valve Cartridges: Conversely, there are configurations having one or two cartridges for pressure valves.
Adjustment Types for Pressure Adjustment:
- Rotary Knob: A rotary knob which is very easy to operate manually.
- Sleeve with Hexagon and Protective Cap: There is a sleeve that has a hexagon shape along with a protective cap to make sure of secureness and tamper-proofing
- Lockable Rotary Knob with Scale: It also possesses a locking feature, which makes it possible to achieve precise adjustment of rotatory knobs on scales thereof.

Function and Section of Z2DB Pressure Relief Valve
Initial Position:
- During initial stages, the closing of valves normally occurs.
Pressure Mechanism:
- Nozzle (2) applies pressure to spring-loaded side of spool (1).
- In addition, nozzle (3) applies pressure to pilot poppet (6).
Activation:
- Pilot poppet (6) opens when the pressure in channel A exceeds its value at spring (5).
- By passing through nozzle (3), hydraulic fluid flows from the spring-loaded side of spool (1), into channel T.
- This shift drops pressure which then moves spool(1) and opens connection A to T, keeping up the one set by spring(5).
Pilot Oil Drain:
- Externally in channel T, pilot oil drains from both spring chambers.
Basic Structure:
- Pressure Valves: These are sandwich plate versions of pilot-operated pressure relief valves designated as Type Z2DB.
- Purpose: Limitation of system’s pressure.
