Product Description
ZDB Series Sandwich Plate Relief Valves (Size 6 & 10)
Product Overview: The ZDB Series is a high-performance sandwich plate relief valve designed for pressure regulation via simple modular stacking. Available in Size 6 (NG6) and Size 10 (NG10), these valves are mounted between the directional control valve and the subplate, significantly simplifying hydraulic circuit layout and saving space. From the ZDB6VP for branch circuit protection to the ZDB10VPV with high-temperature options, this series provides exceptional regulation linearity and long-term operational stability.
Featured models include: ZDB6VA/VB/VP, ZDB6VP2-42/100, ZDB10VP2-41/315V, and ZDB6VP2-4x-200V.
Key Technical Advantages:
Flexible Sandwich Mounting: Compliant with ISO 4401 mounting interfaces, allowing integration into existing manifolds without extra piping, thereby reducing leak points.
Versatile Functional Configurations: * Type VP: Pressure limitation in the P channel.
Type VA/VB: Independent pressure regulation in the A or B channels.
High-Precision Pressure Grading: Available in multiple pressure stages—100 Bar, 200 Bar, and 315 Bar—to meet diverse industrial demands from light to heavy-duty.
High-Temp & Special Seal Options: Models with the V suffix (e.g., 315V) are equipped with Viton (FKM) seals, engineered for high-temperature environments or phosphate ester fluids.
