Description
STVC is a flanged valve. The valve is equipped with self-sealing measuring sockets on the flanges of the valve. El volante tiene un display digital By means of the wheel the valve is set at the desired flow or kv-value according to the diagram. Cuando se ha realizado el ajuste, la válvula puede ser bloqueada. This is done by screwing down the inner spindel to its end position with a 4mm Allen key. After locking, the valve can be closed but cannot however be opened at a higher kv value than the one set. The wheel can be sealed according to the figure. Installation To avoid turbulence which can affect the measuring accuracy, the valve should not be assembled close to bends, branch lines and other valves directly before or after the valve according to the figure. The valve must be assembled with the flow in the direction of the arrow to achieve the correct measuring results.
