Safety information, installation and maintenance Warning
This document does not contain enough information to install the DCV3/B safely. For full details see the Installation and Maintenance Instructions supplied with the product. Note : Flanges, bolts (or studs), nuts and joint gaskets are to be provided by the installer. Disc check valves are non-maintainable (no spares are available). Disc check valves are not suitable for use where heavily pulsating flow exists. Installation note: The DCV3/B is installed in the feedwater line with the flow in the direction of the arrow on the valve body. It may be installed in any plane, and is sandwiched between flanges using suitable gaskets. The valve is centralised by rotating it until the lugs on the body contact the flange joint bolts. The valve must be installed at least 1 metre from the feedpump. It is essential that there is water on both sides of the valve at all times – steam temperatures above 120 °C will cause damage to the EPDM seal.
How to order Example: 1 off Spirax Sarco DN40 DCV3/B boiler feed check valve.
