As an important device in industrial automation control systems, the electric ball valve has seen an increasing use in recent years due to its simple structure and ease of operation. It can be used not only to shut off or connect the medium in pipelines, but also for regulating and controlling fluid flow! However, in pipes under different operating conditions, different models of electric ball valves are used! Users should gain a thorough understanding of the method used to designate electric ball valve models! The methods for editing electric ball valve models include adding additional conditions for the ball valve, selecting the drive type, varying the connection styles, altering the structural design, choosing the type of sealing material, determining the pressure level of the valve, and selecting the material used for the valve body Method for indicating electric ball valve models: Additional codes for ball valves – V indicates a valve core with a V-shaped structure, D denotes low temperature performance, B refers to insulation features, P indicates an eccentric structure, while U, S, and DY generally denote upper-mounted types ； Ball valve name code: Q denotes a ball valve ； Ball valve actuation code: 2 denotes electro-hydraulic, 3 denotes turbine, 6 denotes pneumatic, 7 denotes hydraulic, 9 denotes electric; manual operation has no code ； Connection method code: 1 indicates internal thread, 4 indicates flange type, 6 indicates welding, 7 indicates clamp type ； Structural type code: Floating type: 1 denotes a straight flow channel, 2 denotes a Y-shaped tee, 4 denotes an L-shaped tee, 5 denotes a T-shaped tee ； Fixed type: 0 indicates hemispherical straight-through; 6 indicates four-way flow channel; 7 indicates straight-through flow; 8 indicates L-shaped three-way; 9 indicates Y-shaped three-way ； Sealing material code: B – Babbitt alloy; F – Fluororubber; F46 – Fluorinated lining; H – Stainless steel; J – Rubber lining; M – Monel alloy; N – Nylon plastic; Monel P; Y – Cemented carbide; W – Valve body processed directly ； Pressure rating code: 16 indicates a pressure of 1.6 Mpa ； 150LB denotes pressure in US pounds, with a maximum pressure rating of up to 2500LB ； 5K denotes the daily pressure, with a maximum pressure of 63K; valve body material codes: A for titanium and titanium alloys, C for carbon steel, I for chromium-molybdenum steel, P18-8 series stainless steel, RMo2Ti series stainless steel, S for plastic. Instructions for editing electric ball valve models: VQ947F-16P Stainless steel electric flanged V-type ball valve 1. V: indicates that the valve core has a V-shaped structure 2. Q: denotes a ball valve ； 3, 9: Indicates that the drive mechanism is electric ； 4、4: The connection method is flange connection ； 5, 7: The structural format is a fixed straight-through flow channel ； 6、F: The material of the sealing pair is fluororubber ； 7, 16: Indicates a nominal pressure of 1.6 MPa ； 8、P: Indicates that the valve body is made of stainless steel.
