Series NE-C: Sizes 2” to 12” (50 to 300 mm) are available in both wafer and lug styles. This series is a general-purpose valve with a neck length designed to provide full clearance for the valve top over 2” of insulation on ASME Class 150 pipe flanges.

Series NE-I: Sizes 2” to 12” (50 to 300 mm) are suited for a range of applications in many industries, including food and beverage utilities and process flowlines. This short neck design is offered in a variety of body materials. The valves are designed for installation between ASME Class 125 and 150 flanges.

Series NE-D: The valves in this series can be made in sizes 2” to 12” (50 to 300 mm). The Series NE-D valve is a short-neck valve with body notches to fit popular, lightweight flange patterns, making it ideal for both the bulk material handling and the transportation industries. Valves also will center in ASME Class 125 and 150 flanges. 

Series NEI-T Teflon: Because of the inert, aseptic, non-stick character of Teflon, the DEMCO NEI-T Teflon-lined butterfly valve is ideal for clean lines in food and beverage plants. The Teflon seat consists of a virgin Teflon liner overlaid and bonded to an elastomer EPDM cushion, which provides resilience for sealing.

The Teflon liner extends over the seat faces, completely covering and sealing the resilient material from contact with line fluids.
