Butterfly Valves are excel design in a variety of applications, Cast in both wafer and tapped lug patterns in a variety of material choices, which features a one-piece body for minimum weight and maximum strength and unique stem hole to ensure a dry stem work. Available in sizes 2" through 36"(DN 50 to 900 mm) which application in a wide range of industries: Chemical and petro-chemical, Agriculture, Oil and gas drilling and production, Food and beverage, Water and waste water, Cooling towers, Power, Mining, Marine, etc.
VigorPetro supplys Butterfly Valves equal to DEMCO in full series NE-C, Series NE-I, Series NE-D, Series NF-C.
Series NE-C, Sizes from 2 to 12 in [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 in of insulation on ASME Class 150 pipe flanges.
Series NE-I, Sizes from 2 to 12 in [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, can be made in sizes 2 to 12 in [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.
The valves are designed for installation between ASME Class 125 and 150 flanges. The Series NE-D valve is also available with the short-pattern version (NE-D SP).

Handles and stem extensions:
There are three basic handle designs that are compatible with any 2- to 12-in [50- to 300-mm] valve: ten-position locking, two-position locking, and memory stop. Memory-stop handles provide throttling, which is infinitely adjustable and can be set by a lock nut with a memory-stop setting (adjustable open stop). Handles are available in basic trim, corrosion-resistant trim, and sanitary trim.
VIGORPETRO's DEMCO Type valve weatherproof gear operators are offered with a choice of handwheel. The worm gear has either self-locking set screws to control open and closed positioning or an optional adjustable memory-stop for balance return to a preset open position after closing.
