This specification relates to the supply and installation of Axial Flow Control Valve (Needle Valves type) and Accessories. All materials shall be supplied as specified and shall be subjected to approval. The material of the valve and accessories shall be free from scale, lamination, inherent corrosion and any other defects. Valve and accessories shall be manufactured, inspected and tested in accordance with the applicable codes and standards and shall be capable of withstanding design conditions of the operating systems. The specifications provided herein shall be supplemented with those provided in the Data Sheet. Valve manufacturer shall be certified to ISO 9001:2008. Contractor/Manufacturer shall further warranty the valve against manufacturing defects, material failure and corrosion problems for five years from the date of supply.
Technical Specification for Needle Control Valves
This standard defines the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems above or below ground (see prEN 805, including meter valves), and also suitable for pipe systems carrying raw or treated water (e.g for irrigation, for fire fighting).

This European Standard defines the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems above or below ground (see prEN 805, including the meter valves), and also suitable for pipe systems carrying raw or treated water (e.g. for irrigation, for fire fighting).
Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 1: General requirements
ISO 28921-1:2013 specifies requirements for design, dimensions, material, fabrication and production testing of isolation valves for low-temperature applications. It applies to gate, globe, check, butterfly and ball valves and can be used for other valve types used in low-temperature services. ISO 28921-1:2013 covers isolation valves for use in cryogenic temperature service where the design low-temperature service is ?50 °C down to ? 96 °C. It covers valves with body, bonnet, bonnet extension or cover made of metallic materials. ISO 28921-1:2013 covers valves of nominal sizes DN: 10; 15; 20; 25; 32; 40; 50; 65; 80; 100; 125; 150; 200; 250; 300; 350; 400; 450; 500; 600; 650; 700; 750; 800; 850; 900, corresponding to nominal pipe sizes NPS: 3/8; ½; ; 1; 11/4; 11/2; 2; 21/2; 3; 4; 5; 6; 8; 10; 12; 14; 16; 18; 20; 24; 26; 28; 30; 32; 34; 36. It applies to pressure designations: PN 16; 25; 40; 100; 160; 250; Class 150; 300; 600; 800; 900; 1 500.
