Stem movement way, ( Generic name: non-rising stem) , there are up and down spin lever, Generic name: Ming) The valve is closed ( The disc) Along the core line movement of the valve seat. Because of this, this article types of river closure by the valve and throttle valve is adapted to as truncation or adjusted. 。 Based on disc this way of moving, the seat of his change is relation with directly proportional valve stroke. Simple briefly explained by valve: the valve ( 截止阀、截止阀) Open-close part is shaped disc and tightly closed like the simplest surface or cone, the core of the disc along the seat line for linear motion. Because open or close the valve stem travel relatively short, and have very good truncation function, and because of the changes in the seat of his stroke proportional relationship with the disc, very suitable for traffic regulation. Common by valve type: Japan standard by the end of valve: J41H - 10 k, J41W - 150LB; Speckle tube by the valve: WJ41H, WJ41W; Stainless steel as of valve: J41F, J41W, J41Y; Low temperature by the end of valve: DJ41H, DJ41Y, DJ41F; As of valves: J941F, J941H; Welding of valve: J61Y, J61W, J961Y, J961W; Angle type of valve: J44H, J44W, J47H, J47W; Lining fluoride by valve: J41F46; Pneumatic globle valve: J641F, J641H, J641W; Bevel gear by the valve: J541H, J541W; Keep warm by valve: BJ41F, BJ41H. Q: as of valve type weaving way of answer: by the end of valve type weaving way: by the end of valve with add code: W speckle B, D, low temperature, heat preservation; 1) The valve class code: J expression by the valve; 2) By the valve drive mode: manual without code 6, 5 bevel gear, pneumatic, electric; 3) Flange petition petition forms as of valve: 4, 6, welding; 4) By the valve structure mode: 1 straight through, 2 Z pass-through, 3 t, 4, 5 Y type once-through, 6 balanced straight-through type, 7 balance Angle, 8 pin type; 5) The valve tightly closed material: stainless steel, fluorine rubber, H F N nylon molecular compound plastic Marine valve, Y hard alloy, monel alloy, m. W body directly processing; 6) The valve nominal pressure: 16 pressure 1. The meaning of 6 mpa 16 kilograms, PN1. 6 - 32mpa、IN150LB- 5 - 1500磅 63 k; 7) As of the valve body material: A chromium alloy, carbon steel, chrome molybdenum alloy, P I C stainless steel stainless steel 316, 304, R; Such as: WJ41H - Markings pipe 16 C speckle tube by the valve, W, J by the valve flange, 1, 4 straight through, stainless steel, 16 H pressure 16 kilograms, C carbon steel. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
