Electric precision and small two-seat regulating valve adopts double-guide structure with electronic direct-stroke electric actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc. It is widely used to precisely control the process parameters of gas, liquid, steam and other media, such as pressure, flow, etc. Temperature and liquid level should be kept at a given value. It is especially suitable for medium occasions with large pressure difference, large allowable leakage and not very clean. Products include standard type, bellows sealing type, jacket insulation type and other varieties. The nominal pressure grades of products are PN16, 40, 64; the nominal diameter range is DN25-400. The applicable fluid temperature is -250 ~560 C. Various grades within the scope. Leakage standard is level II or IV. Flow characteristics are linear or equal percentage. Various specifications are available.

【進口電動精小型調(diào)節(jié)閥】工作原理：

精小型電動調(diào)節(jié)閥與被調(diào)介質(zhì)直接接觸，由于閥芯運動，改變了閥芯與閥座間的流通面積，即改變了閥的阻力系數(shù)，從而改變了流經(jīng)調(diào)節(jié)機構(gòu)介質(zhì)的流量，達到了對工藝參數(shù)的調(diào)節(jié)。精小型電動調(diào)節(jié)閥是由智能型電子式電動執(zhí)行器通過支架與單座、套筒調(diào)節(jié)閥連接在一起所 組成。當輸入端無信號時，執(zhí)行器穩(wěn)定在預選的零位，調(diào)節(jié)閥處于全開或全閉的位置，執(zhí)行器的輸出軸通過開合螺 母與調(diào)節(jié)閥的閥桿相連。當輸入端有信號時輸出軸即通過輸入信號按一定比例處在一定的位置，調(diào)節(jié)閥即處于所需開度，從而達到了調(diào)節(jié)和控制的目的。精小型電動調(diào)節(jié)閥分為電開式和電閉式兩種。通過選擇電子式電動執(zhí)行器的正、反 作用開關來實現(xiàn)電開式和電閉式調(diào)節(jié)。

【進口電動精小型調(diào)節(jié)閥】特點：
1、控制簡單，反應快速，且本質(zhì)安全，無需另外再采取防爆措施；
2、執(zhí)行機構(gòu)采用精小型多彈簧結(jié)構(gòu)，實現(xiàn)了小型化，輕型化，對空間的有效利用作出了貢獻；

3、標準化部件設計；互換性強，減少了用戶的庫存量，降低了使用成本，大大提高了性價比。
