Product catalog summary
Overview: This document provides technical specifications and ordering information for ZETKAMA's bellow sealed stop valves, specifically the zBEL model. It includes details on materials, pressure ratings, dimensions, and applications.
Specifications: The valves are designed to meet high tightness standards (leakproofness class A according to EN-12266-1) and are compact and environmentally friendly. They are tested according to EN-12266-1, with flanges drilled as per EN 1092-2 and face-to-face dimensions according to EN 558 series 8. The valves comply with the pressure equipment directive 2014/68/UE and are CE marked for DN≥32.
Materials and Pressure Ratings: The valves are made from grey cast iron (EN-GJL-250) or nodular cast iron (EN-GJS-400-18-LT). The nominal pressure ratings are 6 bar for grey cast iron and 16 or 25 bar for nodular cast iron, with maximum temperatures of 300°C or 350°C depending on the material and type.
Applications: These valves are suitable for various industries, including shipbuilding, heating, refrigeration, air conditioning, and more. They can handle glycol, industrial water, diathermic oil, steam, compressed air, and neutral fluids, although not all applications are suitable for all executions.
Dimensions: The document provides detailed dimensions for different nominal diameters (DN) and pressure ratings (PN), including flange sizes and bolt specifications.
Pressure-Temperature Ratings: Graphs illustrate the allowed working conditions for different materials and pressure ratings, showing the relationship between pressure and temperature.
Types and Ordering Information: The document lists various types of valves with specific features, such as disc connections and material compositions. An example order is provided, detailing how to specify the product number, nominal pressure, diameter, and material when placing an order.
