通径类似于DN50 - DN750阀腔支撑阀座的阀门

Size 2” - 30” Cartridge Seated Valves

特点与优点
Features and Benefits

• 标准双向连接，通径从2”至8”（类似于DN50至DN200），其他通径是圆形和带键的 - 因此能够有效配合支撑手柄或执行器，减少摩擦
  Standard Double D Connection in sizes 2” thru 8”, all others round and keyed - gives positive attachment for handle or actuator support and less friction
• 阀轴在三个位置采用三个标准PTFE（强化聚四氟乙烯）套管保护加固，更有利于阀轴的校准定位和执行器的支撑固定，同时减少摩擦
  Three standard PTFE bushings furnish shaft support at three locations for positive shaft alignment and actuator support as well as less friction
• 标准ISO 5211顶台适配所有类型的执行器、手柄、齿轮操作器，电动和气动执行器
  Standard ISO 5211 top plate accommodates all types of actuators; handles, gear operators, electric and pneumatic actuators
• 精密的锥销确保有效、防震、阀轴阀瓣连接 - 易于现场更换
  Precision taper pins ensure positive, vibration proof, shaft to disc connection - easily field replaceable
• 一体式阀轴确保可靠有效阀瓣定位，标配416不锈钢
  One-piece through shaft ensures dependability and positive disc position, 416SS standard
• 光滑阀瓣表面与阀座表面配合严丝合缝，密封效果极高，有效防止阀轴区域的渗漏
  Smooth finished disc flats “mate” with seat flats to give a highly efficient seal; prevents leakage into the shaft area
• 阀座面不需要法兰垫圈
  Seat face negates need for flange gaskets
• 酚醛树脂衬垫的阀座不会收缩，抗拉伸，防吹出，易于现场更换
  Phenolic backed seat is non-collapsible, stretch resistant, blow-out proof, and easily field replaceable
• 末端应用固定螺丝位于阀门的两个位置，也就是3点钟和9点钟位置，适用的阀门通径达6”（类似于DN150）；更大通径的阀门的末端应用固定螺丝位于阀门的四个位置，位于2、4、8和10点钟位置 - 位于外周的定位从阀体到酚醛衬垫
  Dead end service set screws located in 2 places on valves up to 6” at 3 and 9 o’clock positions, 4 places in larger valves at 2, 4, 8 and 10 o’clock positions - positioned on outer perimeter through valve body to phenolic backing
• 精密的阀瓣表面实现气密性密封关断，确保扭矩最小、阀座寿命更长
  precision profile disc provides bubble-tight shut off and assures minimum torque and longer seat life
• 将弹性合成橡胶与酚醛树脂衬垫密封环结合，能够防止扭曲变形，这是导致阀轴泄漏的主要原因
  Bonding of elastomer to phenolic backing ring protects against distortion, a common cause of shaft leakage
