進口氣動高壓調節閥閥芯采用上導結構，閥體結構緊湊，流體通道呈S型，壓降損失小，流量大，可調范圍廣S氣動高壓調節閥芯部分導向面積大，抗振性能強， 泄漏量符合ANSI FCI 70-2-2006標準，調節閥配用多彈簧薄膜或氣缸執行機構，其結構緊湊，輸出力大。調節閥廣泛應用于高溫及高壓場合。 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
進口氣動調節閥結構作用：
The structure function of the imported pneumatic high pressure regulating valve:進口氣動高壓調節閥是由氣動薄膜執行機構和直通單座籠式閥體組成，閥芯為柱塞型，用于高壓差條件下的閥芯，頭部滲或鑲嵌硬質合金，以抗高壓差情況下的沖蝕和氣蝕，提高閥門的使用壽命，由于氣動高壓調節閥使用的是高壓差環境，介質對閥芯的不平衡力較大，相應的氣動執行機構選型也要加大，氣動單座調節閥配置定位器或定位器，可以根據用戶需求，配進口定位器如西門子定位器、山武定位器等。閥門定位器輸入信號為4-20mA，可以選配輸出信號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.
進口氣動調節閥產品特點：
Product features of imported pneumatic high pressure regulating valve:
進口氣動調節閥就是以壓縮空氣為動力源，以氣缸為執行器，并借助于電氣閥門定位器、轉換器、電磁閥、保位閥等附件去驅動閥門，實現開關量或比例式調節，接收工業自動化控制系統的控制信號來完成調節管道介質的流量、壓力、溫度等各種工藝參數。氣動薄膜單座調節閥的特點就是控制簡單，反應快速，且本質安全，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.
調節閥定位器：
閥門定位器是調節閥的主要附件，與氣動薄膜單座調節閥大大配套使用，它接受調節器的輸出信號，然后以它的輸出信號去控制當調節閥動作后，閥桿的位移又通過機械裝置反饋到閥門定位器，閥位狀況通過電信號傳給上位系統。
閥門定位器按其結構形式和工作原理可以分成氣動閥門定位器、電氣閥門定位器和智能式閥門定位器。
閥門定位器能夠增大調節閥的輸出功率，減少調節信號的傳遞滯后，加快閥桿的移動速度，能夠提高閥門的線性度，克服閥桿的磨擦力并消除不平衡力的影響，從而保證調節閥的正確定位。
