Product catalog summary

Product Overview

The document details the specifications and features of the ZETKAMA Float Valve model 272, designed for industrial water and neutral fluids. It is characterized by high tightness (leakproofness class A according to EN 12266-1), environmental friendliness, and maintenance-free operation. The valve features flanges drilled according to EN 1092-2 and face-to-face dimensions compliant with EN 558-1 series 1.

Application and Features

  • Nominal pressure: 10 bar
  • Maximum temperature: 120°C
  • Nominal diameter range: DN 25 to DN 200
  • Body material: Grey cast iron (EN-GJL-250)
  • Suitable for neutral fluids and industrial water

Materials

The valve components are made from various materials to ensure durability and performance:

  • Body and cover: Grey cast iron EN-GJL-250 (5.1301)
  • Stem, disc, piston sleeve: Stainless steel X20Cr13 (1.4021)
  • Gasket and disc gasket: EPDM, max temperature 120°C
  • Other parts: Zinc galvanized carbon steel (S235JR), malleable cast iron, CuZn39Pb, and other stainless steels (X5CrNi18-10, 1.4301)

Dimensions

The valve is available in two size ranges: DN 25-80 and DN 100-200. Key dimensions include flange diameter (D), bolt circle diameter (K), number of bolts (n), and length (L). For example, DN 100 has a flange diameter of 220 mm, bolt circle diameter of 180 mm, 8 bolts, and length of 310 mm. The document provides detailed dimensional tables for all sizes.

Pressure-Temperature Ratings

The valve is rated for PN 10 pressure class with an allowed working temperature range from -10°C to 120°C. The pressure-temperature graph confirms suitability for typical industrial water applications within these limits.

Types and Ordering Information

The valve type 272 is available with body material A (grey cast iron EN-GJL-250) and nominal pressure PN 10. The stem, disc, and seat ring are stainless steel with an EPDM disc ring. The document provides an example order code: 272 040 B 16, indicating model 272, DN 40, body material B (grey cast iron), and PN 16 pressure rating.
