Описание (английский):

Diese Internationale Norm legt die Anforderungen an die Konstruktion, Funktionsmerkmale und die Herstellung von Schiebern aus Thermoplasten zum Absperren fest sowie deren Anschluss an das Rohr¬leitungssystem, Gehäusewerkstoffe und Druck/Temperatur-Zuordnungen zwischen – 40 °C und + 120 °C, für eine Lebensdauer von 25 Jahren. Sie legt auch die entsprechenden Prüfungen fest. Diese Internationale Norm gilt für hand- und kraftbetätigte Armaturen, die in industrielle Rohrleitungssysteme eingebaut werden, unabhängig vom Einsatzbereich und dem zu befördernden Medium. ANMERKUNG 1 Industrielle Rohrleitungssysteme umfassen auch Rohrleitungen für Wasserversorgung für allgemeine Zwecke, Entwässerung und Entsorgung. ANMERKUNG 2 Rohrleitungssysteme für Wasser für den menschlichen Gebrauch können besonderen Anforderungen unterliegen. Diese Internationale Norm erstreckt sich auf die folgenden DN-Bereiche: DN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300 und DN 350 sowie auf die folgenden PN- und Class-Bereiche: PN 6, PN 10, PN 16 und Class 150.

Overview

EN ISO 16139:2006/A1:2019 (CEN endorsement of ISO 16139:2006 Amendment 1) amends the international standard for industrial gate valves made from thermoplastic materials. The amendment updates the nominal diameter (DN) and pressure rating (PN/Class) ranges, material and testing references, and specific design and performance requirements. It also includes Annex ZA linking the standard to the EU Pressure Equipment Directive (2014/68/EU) for presumption of conformity where applicable.

Key scope items added by Amendment 1

Declared DN range: DN 10 to DN 350 (specific DN values listed).
Declared pressure ratings: PN 6, PN 10, PN 16 and Class 150.
Material types covered: ABS, PE, PP, PVC-C, PVC-U, PVDF.

Key topics and technical requirements

Materials and selection: Valve body and bonnet/cover materials must be selected from specified ISO standards (ISO 15493, ISO 15494, ISO 10931) and conform to the listed thermoplastic materials.
Design strength and testing: Design strength is verified through the body pressure test and long-term behaviour test of the complete valve in accordance with ISO 9393-2.
Face-to-face dimensions: For flanged valves, dimensions are to be selected from EN 558; for other end connections they are manufacturer-defined.
Leak-tightness and seat testing: Seat and packing/shell leaktightness must be demonstrated on complete valves per ISO 9393-2 requirements.
Rating factors (f): Amendment 1 updates Table 1 to provide minimum rating factors for a design lifetime up to 25 years, by material and temperature (values provided for ABS, PE, PP, PVC-C, PVC-U, PVDF). Manufacturers may declare additional rating factors where noted.
Manual operation forces: Manual opening/closing forces are governed by EN 12570 limits and must maintain serviceability after applied forces.
Regulatory linkage: Annex ZA maps clauses to essential requirements of Directive 2014/68/EU (Pressure Equipment Directive).

Practical applications and users

Useful for manufacturers designing and producing thermoplastic gate valves to meet harmonized European and ISO requirements.
Reference for testing laboratories and quality assurance teams to verify design strength, leak-tightness and long-term behavior.
Used by procurement/specification engineers, plant designers and asset owners specifying valves for chemical processing, water treatment and industrial fluid systems where thermoplastic valves are preferred.
Helps notified bodies and conformity assessors evaluate compliance with the Pressure Equipment Directive when the standard is cited in the Official Journal.
