As one of the leading f4 metal seat cast iron gate valve,Website: , f4 rising stem metal seat cast iron gate valve, f4 non-rising stem brass seat cast iron gate valve, f4 non-rising stem metal seat cast iron gate valve manufacturers and suppliers in China and equipped with a productive factory, Shanghai Hugo Valve Co.,Ltd is always at your service. Description DIN 3202-F4 series metal seat cast iron gate valve is a valve with single wedge disc, which can meet the serious requirements in industrial field. For ductile iron body, our size range can be DN50 - DN 900. General design have the advantage as bellow :1, reasonable design, compact structure, easy operation.2, good cast iron gate valve performance, when the ductile iron gate valve is fully opened, the flow resistance coefficient is small, valve port is smooth and straight, without pressure loss, sealing surface have small washout and erosion from medium.3, used stainless steel or bronze as sealing material, there is long longevity.4, small torque, easy to open and close, very simple to operate too.5, two-way sealed design, there is no limitation for medium direction.Component 1 Body Cast Iron / ductile iron 2 Wedge Ductile iron+brass Ductile iron+bronze Ductile iron+stainless steel 3 shaft Stainless steel 4 Bonnet Gasket EPDM/NBR 5 Bonnet Cast Iron / ductile iron 6 HandWheel Ductile iron Application STAND-ARD DESIGN CODE DIN3352 INSPECTION&TEST DIN 3230 END STANDARD DIN /EN1092 FACE TO FACE DIN3202-F4 Test Pressure Working pressure PN 10 PN 16 Shell pressure 1.5 Mpa 2.4 Mpa Seat pressure 1.1 Mpa 1.76 Mpa Dimensions                                                                                                                                                                                Unit : mm DN 40 50 65 80 100 125 150 200 250 300 350 400 500 600 L 140 150 170 180 190 200 210 230 250 270 290 310 350 390 H No-rising Stem 276 296 330 343 372 463 480 603 729 774           Rising Stem 395 453 496 566 685 742 961 1138 1266           D (PN10) 150 165 185 200 220 250 285 340 395 445 505 565 670 780 D (PN16) 150 165 185 200 220 250 285 340 405 460 520 580 715 840 W 160 160 160 200 200 260 260 320 400 400 460 460 560 650
