Full advantage of the most forged steel gate valve Forged steel gate valve 11 described the advantages are as follows: 1 forged steel gate valve fluid resistance is small, medium distressed by the sealing surface brush and water erosion. (2) forged steel gate valve for Class150 ~ 2500, operating temperature -29 ~ 425 ℃ (carbon steel) or -29 ~ 500 ℃ (stainless steel) of small diameter pipeline, the pipeline used to cut off or connected to the media. 3 simple welded forged steel valve body, a short length of the structure, manufacturing process, good for a wide range. 4 gate is placed perpendicular to the valve body, and the level of cut-off valve flap is placed in the valve body, valve and thus shorter than the length of the structure. 5 forged steel gate valve of the internal media channel is through the medium flowing through the valve does not change its flow direction, so the fluid resistance. 6 forged steel gate valve movement direction perpendicular to the direction of the fluid can be fully open and fully closed. 7 use of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. 8 socket weld forged steel gate valve medium flows unrestricted, non-spoiler, not reduce the pressure. 9 very good sealing performance by the erosion of full-time small sealing surface. 10 stainless steel forged steel gate valve opening and closing more effort. 11 is relatively simple shape, the casting process is better for a wide range.

锻钢闸阀优点介绍11点如下： 1.锻钢闸阀流体阻力小，密封面受介质的忡刷和侵蚀小。 2.锻钢闸阀适用于 Class150 ～ 2500 、工作温度 -29～425℃(碳钢)或-29～500℃(不锈钢)的小口径管路上，用于截断或接通管路中的介质。 3.对焊锻钢闸阀形体简单，结构长度短，制造工艺性好，适用范围广。 4.闸板是垂直置于阀体内的，而截止阀阀瓣是水平置于阀体内的，因而结构长度比截止阀短。 5.锻钢闸阀阀体内部介质通道是直通的，介质流经闸阀时不改变其流动方向，所以流体阻力小。 6.锻钢闸阀运动方向与流体方向相垂直，能作全开和全关。 7.选用不同的材质，可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质. 8.承插焊锻钢闸阀介质流向不受限制，不扰流、不降低压力。 9.密封性能非常好全开时密封面受冲蚀较小。 10.不锈钢锻钢闸阀开闭较省力。 11.体形比较简单，铸造工艺性较好，适用范围广。
