Product catalog summary

Product Overview

The document presents technical specifications and ordering information for the ZETKAMA 498 series butterfly valve, designed for various industrial applications including cooling water plants, heating installations, drinking and domestic water, gas installations, waste installations, shipbuilding, and power installations.

Application and Features

  • Nominal pressure: up to 16 bar
  • Maximum operating temperature: 110°C
  • High tightness with EPDM seat material
  • Central disc bearing for smooth operation
  • Environmentally friendly design
  • Suitable for cold and heating water, gas, and waste installations

Materials

ComponentMaterial OptionsMax Temperature
BodyGrey cast iron (EN-GJL-250), Nodular cast iron (EN-GJS-400-15) with epoxy coating110°C
DiscDuctile iron with epoxy layer or Stainless steel (X6CrNiMoTi 17-12-2)110°C
SeatEPDM110°C
StemStainless steel (X20Cr13 1.4021)110°C

Dimensions and Pressure Ratings

The valve is available in nominal diameters (DN) ranging from 32 mm to 300 mm, with pressure ratings depending on size and body material:

  • DN 32-150 mm: PN16 (16 bar) for grey cast iron body
  • DN 200-300 mm: PN10 (10 bar) for nodular cast iron body

Detailed dimensional data includes flange sizes, bolt hole patterns, and weights, supporting compatibility with ISO standards (e.g., ISO F-07, F-10).

Types and Ordering Information

The valve types are identified by a code indicating body material, nominal diameter, and pressure rating. For example:

  • 498 A: Grey cast iron body, DN 32-150 mm, PN16
  • 498 B: Nodular cast iron body, DN 200-300 mm, PN10

Ordering requires specifying the product number (index) that includes the valve type, size, and pressure class, e.g., 498 040 C 36 for a DN40, PN16 valve with stainless steel disc and EPDM sealing.

Key Recommendations and Notes

  • Data and specifications are subject to change without notice.
  • The valve design emphasizes environmental friendliness and suitability for a wide range of fluids.
  • EPDM seat material ensures high tightness and compatibility with water and gas applications.
  • Epoxy coating on cast iron components enhances corrosion resistance.
