角座阀技术参数： Technical Data of Angle Seat Valve: 公称压力：PN 1.6 2.5 Mpa Nominal Pressure: PN 1.6 2.5Mpa 控制压力：（DN08~DN50）1.9~10bar （DN65~DN100）4.0~12bar Control Pressure:（DN08~DN50）1.9~10bar （DN65~DN100）4.0~12bar 控制介质：中性气体或空气 Control Medium: Neutral gas, Air 适用温度：普通型：-20~180℃ 高温型：-20~320℃ Applicable Temperature: Normal Temperature: -20~180℃ High Temperature: -20~320℃ 适用介质：水、酒精、油、燃料、蒸汽、中性气体或液体、有机溶剂、酸碱溶液。 Applicable Medium: Water, Alcohol, Oil, Fuel, Steam, Neutral gas or liquid, Organic solvent, Acid and Lye 控制形式：常闭型、常开型、双作用型。 Control Type: Normally Closed, Normally Open, Double Acting 连接方式：螺纹：内螺纹、外螺纹、活接头（螺纹种类：G/BSP/BSPT/PT/NPT） 法兰：国标法兰、德标法兰、美标法兰 焊接：对焊、承插焊 Connection Ended: Thread Ended: Female Thread, Outside Screw, Screw Connector ( Thread Standard: G/BSP/BSPT/PT/NPT ) Flanged Ended: GB, DIN, ANSI Welded Ended: Butt Welded, Socket Welded 特点：Advantages: 1、可视位置指示：可接限位开关或紧急手动装置。 1. Seeable Location Indicator: Be able to access the limit switches and handwheel 2、容易安装：气控头可以作360°旋转，甚至限位开关也可以360°旋转。可方便地安装一到二个限位开关。 2. Easy to install: Pneumatic actuators and limit switches can be made into rotation in any 360-degree; easy to install one and two limit switches 3、先进的气动控制器：加厚工程塑料外壳，安全。低磨损的活塞结构，容量大而低耗气量。内部元件自润滑，免维护。 3. Advanced pneumatic actuator: using thicken Engineering plastics shell to insure valve safty; low wear and tear by the piston structure; high capacity and low air consumption; internal components is self-lubricating and maintenance-free. 4、容易连接：MAMUR标准连接，嵌入式金属接头。可选更小的控制头。 4. Easy to connect: MAMUR standard connection and inbuilt metal connector are suitable for smaller size actuator 5、长寿命导杆：阀杆契形特氟隆（PTEE）密封，避免脏物导入。自润滑，免维护。阀杆经特别处理以确保固定，并能自动校正位置。 5. Long life steam: valve steam uses wedge-shaped PTFE to avoid the dirty; steam are self-lubricating and maintenance-free; after special processing,
