ZMAP型-气动薄膜单座调节阀-气动调节阀

产品详情

一、产品概述Product Overview：

气动薄膜单座调节阀由气动薄膜执行机构和调节阀两大部分组成，它与气动调节器，减压阀、定位器或其他仪表配合使用，达到控制管道内的温度、压力、液位、流量等工艺参数。单座调节阀具有易密封，泄漏量小的优点，但平衡力较大，故工作压差不宜过高。双座调节阀具有流量系数大，不平衡力较小的特点，因而使用广泛.

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.
