Product catalog summary

Product Overview

The ZETKAMA 216 series stop valve is engineered for high tightness and compact installation, compliant with EN 12266-1 leakproofness class A and the Pressure Equipment Directive 2014/68/EU, featuring CE marking for DN≥32. It is designed for versatile industrial applications requiring reliable fluid control.

Key Features

  • High leakproofness (Class A per EN 12266-1)
  • Compact design suitable for diverse industrial uses
  • Environmentally friendly construction
  • Flanges drilled per EN 1092-2
  • Face-to-face dimensions conforming to EN 558 series 8

Materials and Construction

The valve body is available in three primary materials: grey cast iron (EN-GJL-250), nodular cast iron (EN-GJS-400-18-LT), and bronze (CuSn5Zn5Pb5-C CC491K). Other components such as seat rings, discs, stems, hand-wheels, and gaskets use stainless steel grades (e.g., X20Cr13, X12Cr13), brass, bronze, graphite, and galvanized steel, selected according to valve type and pressure rating.

Nominal Pressure and Temperature Ratings

  • Nominal pressures: 6, 10, 16, and 25 bar
  • Maximum operating temperatures vary by material:
    • Grey cast iron: up to 300°C
    • Nodular cast iron: up to 350°C
    • Bronze: up to 225°C

Pressure-temperature rating charts define allowable working conditions for different materials and pressure classes (PN 6, 16, 25).

Dimensions and Flow Characteristics

Detailed flange dimensions, bolt hole patterns, and face-to-face lengths are provided for nominal diameters DN 15 to DN 300. Kv values (flow coefficients) are specified for various sizes and pressure ratings, indicating flow capacity in m³/h.

Valve Types and Variants

  • Multiple stem and disc connection types: fixed rolled stem, nut connection, loose disc with or without spring
  • Materials for stems, discs, and seat rings include stainless steel, brass, and bronze
  • Variants include balancing discs, throttling discs, and position indicators
  • Valve types identified by codes (e.g., 00, 01, 04, 31, 41, 71, 91) reflecting material and functional characteristics

Applications

Suitable for industries such as shipbuilding, heating, refrigeration, air conditioning, glycol systems, industrial water, diathermic oil, steam, compressed air, and neutral fluids. Not all valve executions are suitable for every application; selection must consider specific operational requirements.

Standards and Compliance

  • Leakproofness tested per EN 12266-1
  • Flanges conform to EN 1092-2
  • Face-to-face dimensions per EN 558 series 8
  • Compliant with Pressure Equipment Directive 2014/68/EU, CE marked for DN≥32

Valve Components and Material Specifications

  • Stem and Disc Connection Types: Nut connections, loose discs (with/without springs), throttling discs (with/without position indicators)
  • Material Compositions: Stainless steel, brass, bronze for stems, discs, seat rings; nodular and grey cast iron for valve bodies; bronze alloy CuZn5Zn5Pb5-C for specific parts

Valve Types and Figures

Valve types are designated by figure numbers (e.g., 01, 02, 05, 31, 41, 71, 91), each representing specific stem-disc configurations and materials, including fixed stem-disc with nut, loose disc variants, and throttling discs with position indicators.

Nominal Diameter (DN) and Pressure (PN) Ratings

  • DN range: 15 mm to 300 mm depending on valve type and body material
  • PN ratings: 6, 10, 16, 25 bar, influenced by body material
  • Nodular cast iron supports up to 25 bar for DN 15-200 mm

Valve Ends and Connection Forms

  • Valve ends available in threaded or straight forms
  • Connection types include flange and angle configurations

Ordering Instructions

Orders must specify product number (index) encoding:

  • Figure number (valve type)
  • Body material code
  • Nominal diameter (DN)
  • Nominal pressure (PN)
  • Type code

Example: "216 040 C" indicates figure 216, DN40, PN16, grey cast iron body (EN-GJL-250).
