Nibco NHE3U0L 8 in Swing Check Valve Flanged 125 Lb

Product Description

The NIBCO NHE3U0L is an 8-inch flanged swing check valve from the F-918-B series, designed for commercial, mechanical, and industrial piping systems. The valve features a cast iron body with bronze trim and a bolted bonnet construction. A lever and counterweight actuator assists with disc control, making this valve suited for horizontal swing applications where reliable backflow prevention is required. The 125 lb pressure class rating and 200 psi working pressure make it appropriate for demanding system pressures. This valve is intended for steam and compatible fluid media and is manufactured domestically.

This valve is specified for commercial mechanical and industrial piping installations where a full-size flanged check valve is required. The 8-inch nominal size and flanged end style allow for direct bolt-up integration with standard ANSI 125 lb flanged piping systems. Typical applications include boiler rooms, mechanical equipment rooms, and industrial process piping. The lever and weight assembly assists the disc in closing against low-velocity flow conditions. This valve is not approved for potable drinking water service per California Section 116875 and carries no low-lead compliance designation.
