Products Details

The electric flanged butterfly valve is a kind of valve widely used in the industrial field, with the characteristics of automation, efficiency and reliability. Here are some details about the electric flanged butterfly valve:

Structure and performance:

The electric flanged butterfly valve is mainly composed of the valve body, the butterfly plate, the seal and the transmission device. Its structure adopts the eccentric principle of three-dimensional design, with flexible sealing and multi-layer sealing compatible new technology, making the valve in operation to reduce torque, save energy, with energy-saving characteristics. At the same time, the overall corrosion resistance, high temperature resistance and corrosion resistance reliability are ensured.
Main performance features:

Unique structure, small size, light weight, flexible operation, labor-saving and convenient;
Reliable sealing, can achieve no leakage seal;
Fluid characteristics tend to a straight line, the best;
The three-eccentric principle is adopted to make the sealing surface almost free of wear and prolong the valve life;
Wide range of applications, such as water, steam, oil, air, gas and other media.
Application field:

Suitable for food, medicine, petrochemical, power plants, iron and steel plants, industrial water treatment and high-rise building environmental protection, water supply and drainage pipes to regulate the flow and cut off the best equipment.
Connections and dimensions:

The main connection and size are PN0.6, 1.0MPa.
Model naming method:

The electric butterfly valve model naming system is derived from the national valve selection standard, covering a number of key parameters, such as butterfly valve code, drive mode, connection type, structural design, sealing material, nominal pressure, valve body material and nominal diameter. For example:
Butterfly valve code: D
Drive mode: 9 - electric actuator
Connection type: 4 - flange, 6 - welded, 7 - dish
Structure design: 1 - center line structure, 2 - double eccentric, 3 - three eccentric
Seal/Sealing material: H - stainless steel, W - body finish, Y - alloy, X - rubber, J - rubber lining
Nominal pressure: 10-10bar, 10K - Japanese standard, 150LB - American standard
Body material: Z-gray cast iron, Q-ductile cast iron QT450, C-carbon steel WCB, P-stainless steel 304, R-stainless steel 316, I-chromium molybdenum steel WC6/WC9
Nominal diameter: DN40-2200mm, 2 "-60".
Special Model:

For example, electric flanged soft seal butterfly valve models: D971X, D971F, D971J; Electric flanged hard seal butterfly valve Model: D973H, D973W, D973F, D973Y.
Electric flanged butterfly valves are becoming increasingly popular in industrial applications due to their compact design, lightweight and small installation footprint. Its design not only reduces initial costs, but also provides good sealing performance and reliability.
