INSTALLATION & OPERATION GUIDE
Install the Double Regulating Valve in the pipe line by ensuring the arrow marking on the valve is same direction as piping flow.
To achieve flow measurement accuracy, it is essential that the piping on the inlet and outlet of the valve is straight and has a minimum length equivalent to 5 Diameters (5D) inlet and 2 Diameters (2D) outlet as shown. If the valve is install at the discharge side of a pump set, it is essential that the straight pipe length between pump outlet and valve has a minimum length of 10 Diameters (10D).
Gaskets must be used and assembled between valve and flanges. This will ensure the installation is concentric with pipe line and better accuracy is obtained.
Design flow is achieved by pre-setting valve’s opening position, which could be read from scales at the handwheel. Contact your local distributor for information on electronic commissioning meter.
To lock the pre-setting of the valve, push the limitation ring at the scales at the bottom of the handwheel, tighten the screw using the hexagon wrench.
Valve must not be lifted by holding the handwheel.
