Company Information

Hydropa Hydraulische Erzeugnisse GmbH & Cie. KG, located in Witten, Germany, specializes in hydraulic products. Contact details include phone +49 2302 7012-0, fax +49 2302 7012-47, email [email protected], and website www.hydropa.de.

Product Overview: Pressure Reducing Valves NG 6 (ZN 6 DMD Series)

  • Weight: Approximately 2.3 kg
  • Maximum Operating Pressure: 210 bar
  • Seals: Four O-Rings, type 5-612 (dimensions 8.74 x 1.78 mm)

Technical Characteristics

Performance values are determined at an oil viscosity of 25 cSt and oil temperature of 40°C.

Characteristic Curves

  1. Characteristic Curve 1: Shows the variation of the regulated pressure depending on the flow rate between the inlet port and the use port, and between the use port and the discharge port.
  2. Characteristic Curve 2: Illustrates the differential pressure change between the inlet and use port as a function of flow rate.
  3. Characteristic Curve 3: Depicts the differential pressure change between the use port and discharge port relative to flow rate.

Application Example

The document includes a schematic symbol for the valve according to DIN ISO 1219 standards, illustrating the flow paths and pressure regulation points.

Dimensions

Dimensions are referenced with labels such as A, AAB, and BB, though specific numerical values are not fully detailed in the excerpt.

Critical Parameters and Recommendations

  • Ensure operating pressure does not exceed 210 bar to maintain valve integrity.
  • Use oil with viscosity around 25 cSt at 40°C for optimal valve performance as per test conditions.
  • Regular inspection of O-Ring seals (type 5-612) is recommended to prevent leakage.
