Pneumatic control valve
The United States Miller MILLER brand MS10 series of imported pneumatic valve with single seat pneumatic control valve, pneumatic control valve seat, pneumatic sleeve valve, pneumatic angle type regulating valve, pneumatic control valve three. ML1000 pneumatic diaphragm actuator, ML2000 pneumatic piston actuator and valve seat. The locator, with solenoid valve, pressure relief valve through the 4-20mA/4-12mA/12-22mA/0-5V/1-5V receives the input control signal, and then output the 4-20mA valve position feedback signal, so as to achieve the adjustment of pressure, flow, temperature, level and other parameters. If equipped with intelligent positioner adjustment more convenient, with fault self diagnosis, can reduce maintenance, easy to intelligent control management.
In the technical design of the valve cage with compression seat design, to solve the traditional screw into the valve seat disassembly difficult, leakage and other issues, extending the service life. The open flow design, medium tends to open the valve opening direction, good controllability, flow characteristics and small distortion. According to the working conditions can choose to reduce noise, anti cavitation special valve cage.
