Technical Document Summary

1. Specifications
This document provides technical specifications for pressure relief valves, specifically the ZN 6 DB series. The valves are available in single and double configurations, with a maximum working pressure of 350 bar. The pressure ranges are categorized as 100 (5-100 bar), 210 (5-210 bar), and 350 (5-350 bar). The valves are pilot-operated and designed for use in hydraulic systems.

2. Design and Components
The document includes sectional drawings with seal kits, highlighting the sealing surfaces and dimensions. The design 'H' features a hand wheel, and the valves are shown without protection caps. The document specifies the use of O-rings with different dimensions and materials (NBR 70 and 90 Shore).

3. Performance Curves
Performance curves are provided, showing the relationship between flow rate (Q in l/min) and pressure (p in bar) at an oil viscosity of 24 cSt and oil temperature of 50°C. These curves help in understanding the valve's performance under specified conditions.

4. Applications
Examples of applications are provided, demonstrating the valve's effectiveness in various hydraulic lines. The document emphasizes the valve's role in pressure regulation within hydraulic systems.

5. Contact Information
The document includes contact details for Hydropa Hydraulische Erzeugnisse GmbH & Co. KG, located in Witten, Germany. Contact methods include phone, fax, email, and website.
