Woltmann Turbine Helical Vane Meters Woltmann meters comprises of a rotor with helical blades inserted axially in the flow, much like a ducted fan; they can be considered a type of turbine flow meter. Unlike conventional check valves, the more arduous and frequent the operating cycle the better Norval works. When selecting Norval check valves particular attention should be given to the period that the valve will remain in the open position without a flow reversal taking place. Non-electrical devices and components group II ATEX II 2 GD c T2 Non-electrical Valves 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).

M-Bus (Meter-Bus) Protocol Communications Output M-Bus (Meter-Bus) is a European standard (EN 13757-2 physical and link layer, EN 13757-3 application layer) for the remote reading of water, gas and electricity meters. ISO5211 Pad Mount for Actuator Operation 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. The valve design incorporates a secondary metal seat in the body, providing the required shutoff should the primary seats be destroyed by fire. By using one of our standard mounting plates and fabricated ends, a permutation to meet all requirements can be achieved. Combination Water Meters Combination water meters comprises of a bulk Woltmann insert and a low-flow Volumetric insert or meter, flow is diverted between them by a by-pass valve that is set at a predetermined flow rate.Fire Safe Approved to API 607 4th Edition Valves have been qualified by testing to API standards 607, 4th Edition. As a classification society, DNV GL sets standards for ships and offshore structures – known as Class Rules.

Norval - Northvale Korting Norval - Northvale Korting

This is available in sizes ½” to 2″ and can be supplied with screwed BSP end connections or with push fit ends for easy and quick installation. These check valves are constructed by mounting a number of small cone diaphragm assemblies onto a centre plate which is housed in a mild steel fabricated body. Essentially for ‘foot valve’ applications where single flange bolting to the end of a pipe is necessary. BSI BS EN 331 Approved Gas Product BS EN 331:2015 specifies the characteristics for the construction, performance and safety of ball valves and closed bottom taper plug valves. Can be incorporated in a variety of body configurations or simply built into original equipment as a cone and diaphragm assembly.A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity. They comprise safety, reliability and environmental requirements that vessels and other offshore mobile structures in international waters must comply with. in) to 200 mm (8 in) diameter for mounting between adjacent pipe flanges to BS 4504 NP 16 or equivalent.

The Kramoja region is located in northeastern Uganda and is classified as one of the poorest regions in the world.Suitable for use in chemical and pharmaceutical industries, petrochemical industries, hydraulic installation, compressed air, steam and water systems. 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.

In Amaglimo-Jong village, the entire community relies on a local swamp for all their water-related needs.

PSI to open and can be installed in both horizontal and vertical lines with upward flow or in any intermediate position. For large bore installations we offer the Norval valve in modular form, in sizes 250 mm – 600 mm diameter. Volumetric Positive Displacement Meter Based on the volumetric rotary piston measurement principle, these meters offer the very highest levels of reading accuracy, even at the lowest flow rate.
