Many of our marine valves can be pressure tested, witnessed by a classification society and supplied with 3.1 & 3.2 certification on request, these include Lloyd’s Register of Shipping, DNV-GL (Det Norske Veritas), RINA, Bureau Veritas, Germanischer Lloyds, NK and ABS (American Bureau of Shipping). Please contact sales with your requirements.
Valves have been qualified by testing to API standards 607, 4th Edition. The valve design incorporates a secondary metal seat in the body, providing the required shutoff should the primary seats be destroyed by fire.
The top flange and drilling to ISO5211 specifications offer the widest possible selection of actuation options, as well as direct mount of pneumatic actuators and accessories.
Based on the volumetric rotary piston measurement principle, these meters offer the very highest levels of reading accuracy, even at the lowest flow rate. Optimum accuracy is maintained whether the meter is installed horizontally, vertically or on an incline.
Elster Water Metering (Kent Meters) is an industry leader in the manufactures a comprehensive range of water metering solutions, which includes high accuracy mechanical meters, fully electronic water meters and Smart metering solutions for residential, commercial and industrial sectors.
Meters conform to the European Council Directive on Measurement Instruments which supersedes the Metrological Classes A, B, C etc. The permissible error limits are regulated across Europe by the MID, water meters may measure with an accuracy of +/-5% in the lower flow range and +/-2% in the permanent load range.
EC-Certificate is issued according to Article 8(1) b) ii) of Council Directive 94/9/EC for equipment and protective systems intended for use in potentially explosive atmospheres (ATEX).
Classification, verification, risk-management, and technical advisory to the maritime industry on safety, enhanced performance, fuel efficiency, etc. As a classification society, DNV GL sets standards for ships and offshore structures – known as Class Rules. They comprise safety, reliability and environmental requirements that vessels and other offshore mobile structures in international waters must comply with. DNV GL is authorized by 130 maritime administrations to perform certification or verification on their behalf.
BS EN 331:2015 specifies the characteristics for the construction, performance and safety of ball valves and closed bottom taper plug valves. It also details the test methods and marking provisions. It applies to metallic valves not directly buried for domestic and commercial installations inside or outside of buildings, using gases of the first, second and third family (specified in EN 437) and working up to 0,2 × 105 Pa, 0,5 × 105 Pa, 1 × 105Pa, 5 × 105 Pa and 20 × 105Pa and with temperature limits from – 5 °C or -20 °C to + 60 °C.
Whole products such as valves, boilers & showers undergo mechanical and water quality testing. This type of approval demonstrates full compliance with requirements of the regulations and byelaws, provided the fitting is installed according to any conditions given with the approval.
