The Complete Guide to ISO 15761 Manufacturing Process for Gate Valves

Gate valves are essential components in industrial piping systems, designed to control the flow of liquids and gases. The ISO 15761 manufacturing process gate valve standard ensures these valves meet rigorous quality, safety, and performance criteria. This guide explores every step of the manufacturing journey, from material selection to final testing.

Key Stages in Gate Valve Production

The manufacturing process begins with material procurement. High-grade metals like carbon steel, stainless steel, or alloy steel are chosen based on application requirements. Next, casting or forging shapes the valve body and bonnet, followed by precision machining to achieve tight tolerances. Critical components such as the gate, stem, and seat are meticulously crafted to prevent leaks and ensure durability.

Quality Control and Testing Protocols

Each valve undergoes non-destructive tests, including radiographic and ultrasonic inspections, to detect internal flaws. Pressure tests verify the valve’s ability to withstand operational stresses. Compliance with ISO 15761 guarantees that every gate valve delivers reliable shut-off capabilities and longevity in demanding environments.
