The Complete Guide to ISO 15761 Manufacturing Process for Gate Valves
Gate valves play a critical role in industrial flow control systems, and adhering to the ISO 15761 manufacturing process gate valve standard ensures superior quality, reliability, and safety. This guide explores the essential stages of manufacturing, key features, and benefits of ISO 15761-compliant gate valves.
Material Selection and Design
The manufacturing process begins with meticulous material selection. High-grade materials like carbon steel, stainless steel, or alloy steel are chosen based on the valve’s intended application. Designers use advanced CAD software to create precise blueprints that meet ISO 15761 specifications, ensuring optimal performance under high-pressure conditions.
Casting and Forging
Valve bodies and bonnets are typically formed through casting or forging. Forging is preferred for high-stress environments as it enhances mechanical strength and eliminates internal defects. Each component is inspected for dimensional accuracy and structural integrity before proceeding to the next stage.
Machining and Assembly
CNC machining ensures components like the gate, stem, and seat are manufactured to exact tolerances. Surface treatments, such as hardening or coating, are applied to improve wear and corrosion resistance. During assembly, parts are carefully fitted and tested to prevent leaks and ensure smooth operation.
Key Features of ISO 15761 Gate Valves
ISO 15761-compliant gate valves offer robust construction, tight sealing, and long service life. They are designed for full open or full close applications, minimizing pressure drop when fully open. These valves undergo rigorous testing, including shell tests and seat leakage tests, to guarantee compliance with international standards.
