一、產(chǎn)品概述Product Overview：

氣動(dòng)薄膜單座調(diào)節(jié)閥由氣動(dòng)薄膜執(zhí)行機(jī)構(gòu)和調(diào)節(jié)閥兩大部分組成，它與氣動(dòng)調(diào)節(jié)器，減壓閥、定位器或其他儀表配合使用，達(dá)到控制管道內(nèi)的溫度、壓力、液位、流量等工藝參數(shù)。單座調(diào)節(jié)閥具有易密封，泄漏量小的優(yōu)點(diǎn)，但平衡力較大，故工作壓差不宜過高。雙座調(diào)節(jié)閥具有流量系數(shù)大，不平衡力較小的特點(diǎn)，因而使用廣泛.

Thin-film single-seat pneumatic control valve by the pneumatic diaphragm actuator and control valve of two parts, with pneumatic regulator, reducing valve, positioning, or used in conjunction with other instruments, to control the temperature inside the tubes, pressure, level, flow and other process parameters. Single-seat control valve with easy to seal, leakage of small advantages, but a large counterweight, the working pressure should not be too high. Seat valve with a flow coefficient, the unbalanced force of smaller features, which are widely used.
