Industrial Piping. Cast Iron Gate Valves

This document specifies the technical requirements and test methods for cast iron gate valves intended for industrial applications, covering design parameters, material specifications, and performance criteria to ensure safe operation under varying pressure and temperature conditions. It defines the classification of valve types, dimensional tolerances, and pressure-temperature ratings relevant to general industrial piping systems. The standard addresses the material properties of cast iron components, ensuring adequate mechanical strength and resistance to corrosion in typical service environments. Detailed procedures are outlined for manufacturing quality control, including visual inspections, pressure testing, and functional checks during the acceptance phase. It establishes uniform criteria for the valve's structural integrity, sealing efficiency, and operational reliability across different pressure classes. The scope encompasses both flanged and end-connected configurations commonly used in municipal water supply, industrial processing, and utility distribution networks. All provisions aim to harmonize product specifications to facilitate interchangeability and maintain consistent performance standards across the market. The document serves as a reference for manufacturers, suppliers, and users to ensure compliance with established technical norms for cast iron gate valve production and application.
