| For the initial purchase of Voto valve products and the lack of knowledge of the valve, friends should understand this editing method, is the correct selection and understanding of the purchase of Voto valve products, This model editing method is combined with the international model editing and the company's internal technology selection to make a correct representation. Mainly for the additional code of the gate valve, gate valve code, drive mode, connection form, structural form, sealing material, pressure level, valve body material to explain, I hope to help the majority of users. Description of the model description of the precision casting gate valve: Ball valve additional code: V means the valve core has a V-shaped structure, D means low temperature, B means heat preservation, P means eccentric structure, U and S and DY means top-loading type; Ball valve name code: Z means gate valve; ball valve drive code: 2 means electrohydraulic, 3 means turbine, 6 means pneumatic, 7 means hydraulic, 9 means electric, manual no code; Connection code: 1 for internal thread, 4 for flange type, 6 for welding, 7 for clip type; structure type code: floating type: 1 means straight flow to 2, 2 means Y type tee, 4 means L type three Pass, 5 means T-type tee; Fixed type: 0 means hemisphere straight through, 6 means four-way flow path, 7 means straight-through flow, 8 means L-shaped three-way, 9 means Y-shaped three-way; Sealing material code: B babbitt, F fluoro rubber, F46 lining fluorine, H rust steel, J lining rubber, M Monel alloy, N nylon plastic, Monel P, Y hard alloy, W valve body direct processing; Pressure level code: 16 means the pressure is 16 kg (1.6Mpa) up to 64Mpa; 150LB means American standard pound pressure, the maximum pressure level can reach 250B (150LB=1.6MPA/300LB=2.54.0mpa/400LB=6.4mpa/600LB=10mpa); 5K indicates the daily pressure, the maximum pressure is 63K; |
