BI-DIRECTIONAL VALVE WITH FLOW-SELECTABLE FEATURE
<![endif]>013R9355
Installation of valve
The valve is a bi-directional valve * and can be installed horizontally or vertically in either the flow or return pipe.
A built in flow direction selection feature can be used to eliminate the risk of water hammer.
Troubleshooting
In the unlikely event of water hammer being encountered turn the setting ring (see diagram 4) to the other setting. Alternatively if commissioning the whole system, establish the flow direction through each valve using the diagrams below.
If the flow direction needs to be changed there is no need to remove the valve, simply turn the setting ring.
