BOSS | Fig. 901S | 1.1/2" BSP DRV Venturi Commissioning Valve

CLEARANCE ITEM - OLD SURPLUS WAREHOUSE STOCK - LIMITED AVAILABILITY

DN40S, 1.1/2" Product Code: 22074050

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 10 – 60kPa except on the ultra low flow valves where the signal should
be between 1 – 4.7kPa. The valve is suitable for mounting with the test points
pointing down. The commissioning station has an accuracy of +/-3%.
