A waste cone with sight glass is installed at the outlet of the fire pump relief valve and allows the flow of water relieved through the valve to be checked visually. The relief valve outlet connection and the need for visual flow verification are considered when selecting a fire pump waste cone.
The Cla-Val Model WC-1 is designed for use with UL/FM approved fire pump pressure relief valves and is manufactured in accordance with NFPA 20 requirements. Two 2″ 316 stainless steel sight glasses on the conical body make it easy to check whether the relief valve is open.
The body is cast in one piece from ASTM A536-65 ductile iron and contains no welds. Interior and exterior surfaces are coated with fusion-bonded red epoxy. It is supplied as standard with 150# FF and 300# RF flanges.
Suitable for onshore and offshore applications, the WC-1 can also be manufactured in optional materials such as NAB, Monel, 316 stainless and super duplex for seawater and heavy-duty conditions. Size is selected according to pump flow. Waste cones can also be supplied under the Weflo brand.
