Butterfly valve type

Butterfly valve type introduction

Butterfly valve type preparation method (in sequence) : for example, D343H-10C ①D ②3 ③4 ④3 ⑤H ⑥10 ⑦C  
 Additional code: BD thermal butterfly valve, SD telescopic butterfly valve, TLD desulfurization butterfly valve, DH check butterfly valve, DKS fast butterfly valve, FDBD square butterfly valve;  
 (1) Butterfly valve code: D indicates the butterfly valve;  
 (2) Transmission form code: lever (omitted), 3 means gear drive, 6 means pneumatic drive, 7 means hydraulic drive, 9 means motorized drive;  
 
(3) Connection code: 4 flange type, 6 welding, 7 wafer type;  
 (4) Structure form code: 1 means concentric, 2 means double eccentric, 3 means three eccentric, 4 means change eccentric, 5 means single eccentric;  
 
(5) Sealing material code: H---Stainless steel, X or J---Rubber, F---Vition, F4---PTFE,F46---FEP, M---Monel alloy, Y---Stellite, W---valve body direct processing;  
 
(6) Pressure grade code: 10= PN1.0mpa, 16=PN1.6, 25=PN2.5, 40=PN4.0, PN is the domestic pressure code, Mpa is the unit of pressure;  Class150LB=1.6mpa, 300LB=2.5-4.0mpa, Class is the American standard code, LB is the American standard pound unit.  
 
(7) Butterfly valve body material code: C---cast steel, P---stainless steel 304, R---stainless steel 316, AL---special alloy steel, Z---cast iron, Q---ductile iron.  
 
The above is the common butterfly valve code, because of the special conditions of the customized products, can be selected according to the design scheme.
