FC-Z Series Self-Actuated Control Valve

Overview and application

The self-actuated control valve can be designed with single-seat valve plug or sleeve valve plug according to working conditions. It can accurately control the upstream/ downstream pressure at a preset value. It is widely applied for working conditions that require automatic control of downstream pressure but there is no power source at site such as gas or electricity in petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry and electric power industry.
