Abstract

Overview

ISO 21787:2006/Amd 1:2019 is an important amendment to the international standard that specifies requirements for industrial globe valves made from thermoplastic materials. Published by the International Organization for Standardization (ISO), this amendment updates material specifications, testing methods, dimensional standards, and performance criteria to ensure high-quality, reliable, and safe globe valves for industrial applications.

Key Topics

Scope and Range: Applies to globe valves with nominal diameters (DN) from 10 to 350 and pressure ratings (PN) of 6, 10, 16, and Class 150.
Material Requirements: Specifies use of thermoplastics such as ABS, PE, PP, PVC-C, PVC-U, and PVDF following updated ISO material standards to ensure durability under fluid pressure conditions.
Design Dimensions: Face-to-face dimensions of flanged valves align with European Norm EN 558:2017, while other types rely on manufacturer specification.
Pressure and Strength Testing: Long-term performance, design strength, and leaktightness are verified through tests compliant with ISO 1167-1 and ISO 9393-2, ensuring valves withstand operational and surge pressures safely.
Marking and Traceability: Valves must bear comprehensive markings including DN, PN/Class, material type, manufacturer identification, and pressure/temperature limits to support safety, conformity, and quality control.
Operating Forces: Manual operating forces are regulated per EN 12570, guaranteeing ease of use while maintaining valve functionality after force application.
Updated References: Incorporates current international standards for piping systems, fasteners, flanges, and valve actuator attachments to maintain compatibility and interoperability.
Conformity with PED: Aligns with the European Pressure Equipment Directive (2014/68/EU), giving presumption of conformity for valves sold within the EU market.

Applications

Industrial globe valves manufactured in compliance with ISO 21787:2006/Amd 1:2019 are used extensively in systems requiring reliable flow regulation of fluids, especially where chemical resistance and long-term performance are critical. Common applications include:

Chemical Industry: Handling corrosive media with thermoplastics valves that resist degradation.
Water and Wastewater Treatment: Regulating water flow with valves offering leak-tight sealing and pressure resilience.
Food and Beverage Processing: Ensuring sanitary and safe flow control with approved plastics materials.
Pharmaceutical Manufacturing: Maintaining purity and avoiding contamination through compatible valve materials.
Industrial Piping Systems: General flow control in manufacturing processes where durability and operational efficiency are paramount.

The standard supports manufacturers and engineers in selecting and certifying globe valves that meet current global safety, quality, and environmental requirements.

Related Standards

Compliance with ISO 21787:2006/Amd 1:2019 involves referencing and integrating related standards such as:

ISO 1167-1:2006: Thermoplastics pipes and fittings testing for internal pressure resistance.
EN 558:2017: Valve face-to-face and center-to-face dimensions for flanged systems.
ISO 9393-2: Testing procedures for valve performance including strength and leak tightness.
ISO 15493 and ISO 15494 Amendments: Specifications for plastics piping systems components.
EN 12570: Manual operating forces for valves.
EN 10921:2018: Flanges and flange joint specifications for steel components.
ISO 5210:2017: Actuator attachments for multi-turn valves.
EU Directive 2014/68/EU (PED): Regulatory framework for pressure equipment conformity in European markets.

Adhering to these related standards ensures globe valves meet stringent safety, quality, and interoperability criteria required in modern industrial piping systems.

ISO 21787:2006/Amd 1:2019 serves as a comprehensive benchmark for manufacturers, engineers, and quality assurance professionals aiming to implement reliable thermoplastic globe valves that deliver optimal performance under industrial operating conditions, while conforming to current international and European regulatory requirements.
