1 Venturi Commissioning Valve (FODRV) & (DRV) Cu x Cu Compression DN-DN Balancing Valves BOSS TM 900SC Venturi FODRV DN1- BOSS TM 901SC Venturi DRV DN1- Specification The commissioning station and DRV incorporates a characterised regulating needle combined with an isolating ball valve. The double regulating feature allows the valve to be isolated without movement of the set regulation point. The needle is regulated using an allen key. The valve is suitable for mounting in any orientation. The flow rate is measured using a fixed orifice Venturi cartridge with double seal test points inserted into the valve body. These functions are incorporated into a single fitting which contains any up and down stream lengths required for laminar flow conditions except when installed in close proximity to a pump. The commissioning valve should produce a signal of between except on the ultra low flow valves where the signal should be between The valve is suitable for mounting with the test points pointing down. The commissioning station has an accuracy of +/-%. 4.1

27 Butterfly Venturi Commissioning Valve FODRV & DRV 6mm 0mm (PN16) Balancing Valves BOSS TM 900XSS Venturi FODRV DN6-0 BOSS TM 901XS Venturi DRV DN6-0 The larger sizes of the BOSS TM Venturi consist of a gear operated cast iron butterfly valve fitted with a double regulation feature mounted on a carbon steel tube fitted with the Venturi device. These Venturi valves are available with flanged connections in a long or short pattern. The range covers sizes from 6mm (2 1 2in) to 0mm (12in). This range of valves complement the DZR brass offering of Venturi valves and the long pattern version includes, within the valve, the upstream lengths which are required for accurate commissioning ( times the valve diameter). The flow is calculated based on the pressure differential across the nozzle. The measurement accuracy is better that +/-% and this accuracy is maintained over the entire measuring range from 1 to. The BOSS TM Venturi is available in two variations: FODRV: Includes regulation, isolation and a flow measurement unit. DRV: Includes regulation and isolation unit. Benefits Regulation, Isolation and flow measurement in one single unit Measurement across a nozzle measurement better than +/-% Same measuring accuracy across the entire measuring area from 1 Regulation setting remains unchanged when isolated 4.27

28 Butterfly Venturi Commissioning Valve (FODRV) Specification The commissioning station incorporates a characterised regulation butterfly valve close coupled to a fixed orifice Venturi flow measuring device with double seal test points. The double regulating feature allows the disc setting to be locked in position using an allen key and return to the exact position after isolation. The long pattern incorporates all upstream lengths required for greater accuracy of flow measurements except when installed in close proximity to a pump.

Regulation/Operation The valve is adjusted by rotating the hand wheel on the gearbox. The water flow increases when the hand wheel is turned anti-clockwise and reduces when turned clockwise. By using a flow meter or other measuring device the flow rate through the BOSS TM Venturi can be measured and adjusted to meet the specific requirements of the system. The gearbox can be locked against the memory stop when the desired setting is achieved. Once locked the valve can be isolated and when re-opened cannot travel past the memory stop. Isolation The valve is isolated by turning the hand wheel clockwise up to the S position stamped on the gearbox. After isolation the valve is re-opened to the pre-set position when the indicator cam reaches the memory stop. Measurement measurements are via the Venturi nozzle. The BOSS TM Venturi has two test points (P/T plugs). The high pressure test point is identified by the RED retaining clip and the low pressure test point is identified by the BLUE retaining clip. The pressure differential measured between these test points can be used to calculate the actual flow through the Venturi. This differential can be measured using a flow meter or other measuring device. This is converted into a flow rate of litres per second () or metres cubed per hour (m /h) either electronically or using a calculation formula.
