結(jié)構(gòu)特點(diǎn)和用途Structural Feaures and Application

本系列調(diào)節(jié)閥由閥門和HA-系列薄膜氣動(dòng)執(zhí)行機(jī)構(gòu)組成。采用平衡式閥瓣和雙座套筒寬導(dǎo)向結(jié)構(gòu)，有效消除機(jī)械振動(dòng)噪聲并提高使用壽命。采用低流阻、高容量閥體和套筒，具有流量大、調(diào)節(jié)范圍大以及很小的密封泄露（見(jiàn)性能指標(biāo)）。執(zhí)行機(jī)構(gòu)接受0.14，,028,0.4MPa的起源動(dòng)力，控制調(diào)節(jié)閥開度，實(shí)現(xiàn)對(duì)管路內(nèi)介質(zhì)的壓力、流量、液位等受控參數(shù)的控制。

本產(chǎn)品適用于低流阻、大容量和有中等密封要求（ANSI B16.104 Ⅲ級(jí)）的工況條件。廣泛應(yīng)用于化工、輕紡、冶金、火電等行業(yè)的自動(dòng)控制系統(tǒng)中。

This series valve by valve and HA - film series pneumatic actuators. With balanced disc and the two-seater sleeve width guide structure, effectively eliminate the mechanical vibration noise and improve the service life. Body and sleeve with low flow resistance, high capacity, large flow, the adjusting range is large and small seal leak (see performance index). Enforcement agencies to accept, 0.14, 028,0.4 MPa the origin of the power, control the valve opening, implementation of piping within the medium pressure, flow, liquid level control of the controlled parameters, such as.

This product is suitable for low flow resistance, large capacity, and have a secondary containment requirements (ANSI B16.104 Ⅲ) conditions. Are widely used in chemical industry, textile, metallurgical, coal and other automatic control system.
