The Methodology Behind Electric Butterfly Valve Model

The model designation system for electric butterfly valves in China is derived from national standards for valve selection, encompassing several key parameters:

• Butteryfly Valve Code: D
• Actuation Method: 9 – Electric Actuator
• Connection Type: 4 – Flange Type, 6 – Welding, 7 – Wafer Type
• Structural Design: 1 – Center Line Structure, 2 – Double Eccentric, 3 – Triple Eccentric
• Seat/Sealing Material: H – Stainless Steel, W – Valve Body Processing, Y – Alloy, X – Rubber, J – Rubber Lining
• Nominal Pressure: 10 – 10Bars, 10K – Japanese Standard, 150LB – American Standard
• Valve Body Material: Z – Gray Iron, Q – Ductile 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”

These parameters, except for temperature and medium, are reflected in the model, please kindly specifying the operating medium and temperature during selection.
