Purpose: paraboia stop valve ***** DIN is applicable to the pipet are used in various industries such as ***** industry. ***** fertilizer, electric power industry etc under nominal pressure of PN1.6-16MPa and working temperature of -29-350? as switch and the adjustment of flutural features: ***** product has logical structure, reliable seal, exceilent performance and nice design. ***** seal surface is build-up welding with Co hard ailoy, which is *****-resistant, has good friction resistant and long life. ***** stem is quenched and tempered.and its surface is treated by nitratment, thus it has good corrosion resistant and friction resistant. ***** has double seal capability, thus is more reliable. ***** stem may show the position of lift, thus it is clearer. ***** part material, flange and butt weld end dimension may be selected according to current operationg condition and users'requirement. so that meet the requirements of various engineering structure formation :BB-BG-O, S&Y Driving maner:hand-operrated, Electric-auctuated Design standand:DIN3358 FACE TO FACE:DIN3230 Flanged ends:DIN2543-2545 TEST AND INSPECTION;DIN3230
