with the continuous progress of high-tech development, working condition requirements also more and more high, the new type butterfly valve products are entering the market, the increase of additional conditions for butterfly valve, transmission mode of upgrading, the change of the structure, heat resistance, pressure to improve corrosion resistance of the material requirements, produce a series of new type butterfly valve products. For this company, combined with international standard fusion in-house manufacturing for each product integration, correct selection and to Taiwan for industry minister butterfly valve have more understanding. , here is the company's latest butterfly Industrial Valves model establishment method of the latest specification, if you have any confused please contact our technical engineers for you. The butterfly valve model establishment method ( According to the order) : D343H - for example 10 C (1) D (2) three (3) (4) 3 (5) 4 H additional code: 6 to 10 7 C butterfly BD insulation butterfly valve, SD telescopic butterfly valve, TLD desulfurization, DH check butterfly and DKS butterfly valve, FDBD square louvers quickly; Compiled code: (1) butterfly valve D said butterfly valve; (2) the transmission form code: manual ( Omitted) Said, 3 turbine drive, pneumatic drive 6 said, 7 said hydraulic, 9 said electric; (3) connection code: 4 flange welding, 6, 7 the wafer; (4) structure code: 1 according to linear, 2 said the double eccentric, said three eccentric 3 and 4 said becomes eccentric, 5 single eccentric; (5) sealing material code: H, X stainless steel rubber, ptfe, FX compound rubber, F M monel alloy, hard alloy, Y W body directly processing; 6 classes code: 10 = PN1. 0 mpa, 16 = PN1。 6、25 = PN2。 5、40 = PN4。 Is 0, the PN code of domestic pressure, the MPA is the unit of pressure; Class150LB = 1。 6mpa、300LB=2. 5 - 4. 0 mpa, Class is American American standard code, LB Class is American standard units. All landowners shell material code: cast steel, stainless steel 316 stainless steel 304, P R C, AL special nodular cast iron, cast iron, alloy steel, Z Q N nylon. Above for common butterfly related code, need to custom-made product, due to special conditions according to the selection of design scheme.
