进口气动高压调节阀阀芯采用上导结构，阀体结构紧凑，流体通道呈S型，压降损失小，流量大，可调范围广S气动高压调节阀芯部分导向面积大，抗振性能强， 泄漏量符合ANSI FCI 70-2-2006标准，调节阀配用多弹簧薄膜或气缸执行机构，其结构紧凑，输出力大。调节阀广泛应用于高温及高压场合。 imported pneumatic pressure regulating valve on the valve spool with guide structure, compact structure, the fluid channel is S, pressure drop, flow rate, wide adjustable range S pneumatic pressure regulating valve core part oriented area, strong resistance to vibration performance, leakage with ANSI FCI 70-2-2006 standard, equipped with multi spring diaphragm regulating valve or pneumatic actuator, which has the advantages of compact structure, large output force. Regulating valves are widely used in high temperature and high pressure occasions

进口气动调节阀结构作用：

The structure function of the imported pneumatic high pressure regulating valve:进口气动高压调节阀是由气动薄膜执行机构和直通单座笼式阀体组成，阀芯为柱塞型，用于高压差条件下的阀芯，头部渗或镶嵌硬质合金，以抗高压差情况下的冲蚀和气蚀，提高阀门的使用寿命，由于气动高压调节阀使用的是高压差环境，介质对阀芯的不平衡力较大，相应的气动执行机构选型也要加大，气动单座调节阀配置定位器或定位器，可以根据用户需求，配进口定位器如西门子定位器、山武定位器等。阀门定位器输入信号为4-20mA，可以选配输出信号4-20mA。imported pneumatic pressure regulating valve is a pneumatic diaphragm actuator and through single seat cage type valve body, as the plunger type valve spool, for the condition of high pressure, head infiltration or inlaid with hard alloy, with anti cavitation and high pressure under the condition of erosion, improve the service life of the valve, the pneumatic pressure regulator the valve is high pressure environment, medium on the spool of the unbalanced force, the corresponding actuator selection should also increase, single seat pneumatic  valve positioner or locator configuration, according to user needs, such as SIEMENS imported locator locator, locator Shanwu etc.. The input signal of the valve locator is 4-20mA, and the output signal 4-20mA can be selected.

进口气动调节阀产品特点：

Product features of imported pneumatic high pressure regulating valve:

  进口气动调节阀就是以压缩空气为动力源，以气缸为执行器，并借助于电气阀门定位器、转换器、电磁阀、保位阀等附件去驱动阀门，实现开关量或比例式调节，接收工业自动化控制系统的控制信号来完成调节管道介质的流量、压力、温度等各种工艺参数。气动薄膜单座调节阀的特点就是控制简单，反应快速，且本质安全，不需另外再采取防爆措施。

imported pneumatic valve is driven by compressed air source to the cylinder as the actuator and valve positioner by means of electrical, converter, solenoid valve, position  valve and other accessories to drive the valve, switch or proportional regulator, receive to complete the flow pressure temperature and other parameters regulating pipeline  signal industrial automation  system. The characteristics of pneumatic thin film single seat regulating valve are simple , quick reaction, and essential safety, and no other measures should be taken.

调节阀定位器：
阀门定位器是调节阀的主要附件，与气动薄膜单座调节阀大大配套使用，它接受调节器的输出信号，然后以它的输出信号去控制当调节阀动作后，阀杆的位移又通过机械装置反馈到阀门定位器，阀位状况通过电信号传给上位系统。
阀门定位器按其结构形式和工作原理可以分成气动阀门定位器、电气阀门定位器和智能式阀门定位器。
阀门定位器能够增大调节阀的输出功率，减少调节信号的传递滞后，加快阀杆的移动速度，能够提高阀门的线性度，克服阀杆的磨擦力并消除不平衡力的影响，从而保证调节阀的正确定位。
