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. Optimum accuracy is maintained whether the meter is installed horizontally, vertically or on an incline. 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. 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. They are commonly referred to as helix meters and are usually used to measure bulk flows.

Multi-Jet Warm Water Meter Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller, whose rotation speed depends on the velocity of water flow. For best accuracy, they should be installed horizontally. Electromagnetic Water Meters The Electromagnetic water meter (Mag Meter) does not have any moving parts and is ideal for potable and wastewater applications or any dirty liquid which is conductive or water based. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity. 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. This allows the combination meter to have a very large measurement range. 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. 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.The Kramoja region is located in northeastern Uganda and is classified as one of the poorest regions in the world.

In Amaglimo-Jong village, the entire community relies on a local swamp for all their water-related needs.This swamp is located about 13 km from the village. Plasson has dug the village a new well. DNV-GL Type Approved Product 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. For many years the Norval Non-Return principle has been very successful throughout most industrial sectors. During discussions with engineers in the Brewing, Soft drinks and Food Industries we established that the Norval principle could be developed to overcome problems encountered with Non-Return Valves in CIP systems.Essentially for ‘foot valve’ applications where single flange bolting to the end of a pipe is necessary. May also be used for bolting to the sides of tanks or bulkheads. Size range 40 mm (1.5 in) to 200 mm (8 in).
