With the progress of high-tech development, working conditions have become more sophisticated, the new valve products are constantly entering the market, additional conditions for the butterfly increasing upgrade transmission mode, the structure changes, temperature and pressure decay requirements of the material increase, resulting in a series of new valve products. SHOWA Showa Valve Company for this binding international standards into the preparation of a breakdown within the company manufactured products integrated industrial correct selection and butterfly valves for SHOWA Showa have more understanding. Here is the latest instructions SHOWA Showa Butterfly Valve's latest model designation, if not understand, please contact our technical engineers for you to explain. ♀ Butterfly Model methodology in order: for example D343H-10C ①D ②3 ③4 ④3 ⑤H ⑥10 ⑦C butterfly Additional code: BD insulation valve, SD telescopic butterfly, TLD desulfurization butterfly, DH return valve, DKS fast butterfly, FDBD square louver ① butterfly valve preparation Code: D indicates butterfly ② Transmission Type Code: manual omission, 3 denotes a turbine drive, 6 denotes pneumatic drive, 7 hydraulic, electric ③ 9 shows connection code: 4 flanged, welded 6, 7 pairs of clip-④ structure code: 1 representation of linear, 2 for double eccentric, 3 represents three eccentric, eccentric 4 represents change, 5 represents a single eccentric ⑤ seal material code: H stainless steel, X rubber, F PTFE, FX compound rubber, M Monel, Y Carbide, W valve direct processing ⑥ pressure rating code: 10 = PN1.0Mpa, 16 = PN1.6,25 = PN2.5,40 = PN4.0, PN is the pressure of the Code , MPA pressure units Class150LB = 1.6mpa, 300LB = 2.5-4.0mpa, Class US-made American Standard Code, LB is the American standard-pound units. ⑦ Housing Material Code: C steel, P stainless steel 304, R stainless steel 316, AL special alloy steel, Z cast iron, Q ductile, N nylon. The above is a common butterfly related code, because working conditions require special custom-made products, according to the design scheme for selection.
