Check valve zCHE Fig.407

Product catalog summary

Product Overview

The document presents technical details for the ZETKAMA Check Valve model 407, a wafer-type, straight form valve designed for various industrial applications including hot and cold water, low-pressure steam, oil, chemical, and food plants.

Specifications

  • Nominal Pressure: PN16 for DN 40-200; PN10 for DN 250-350
  • Maximum Temperature: 100°C
  • Nominal Diameter Range: DN 40 to DN 350
  • Body Material: Grey cast iron (EN-GJL-250)
  • Seal Material: EPDM
  • Disc and Spring: Stainless steel (X5CrNi18-10)

Features

  • Compact wafer design for space-saving installation
  • Environmentally friendly and maintenance-free operation
  • Suitable for hot and cold water, low-pressure steam, oil, chemical, and food industry plants

Materials

The valve components include:

  • Body: EN-GJL-250 grey cast iron
  • Seal and Sleeve: EPDM
  • Disc, Plate, Spring, Pin: Stainless steel X5CrNi18-10
  • Sling (for DN 125-350): S235JR steel

Dimensions and Hydraulic Characteristics

The document provides detailed dimensional data for nominal diameters ranging from DN 50 to DN 350, including parameters such as outer diameter (D), minimum pipe diameter, length (A), and weight (Q). Kv values (flow coefficients) are also specified, indicating flow capacity at different sizes, e.g., Kv ranges from 8.6 m³/h for DN 50 up to 2783 m³/h for DN 350.

Ordering Information

Ordering codes follow a structured format combining figure number, body material, nominal diameter, nominal pressure, and type. For example, "407 050 C 54" corresponds to a check valve with figure 407, DN 50, PN16 pressure rating, grey cast iron body, and EPDM seat.

Critical Parameters and Recommendations

  • Maximum operating temperature is limited to 100°C.
  • Pressure ratings differ by size: PN16 for DN 40-200 and PN10 for DN 250-350.
  • Material selection ensures corrosion resistance and durability in various industrial environments.
  • Compact wafer design facilitates installation between flanges without additional space requirements.
