Cage type double seater regulating valve
Simple structure, compact, easy to install, maintenance, long service life Cage type double seat regulating valve is mainly used in large flow, high pressure drop occasions
Application
Control valve, also known as control valve, in the field of industrial automation process control, by accepting the control signal of the output of the control unit, with the help of power operation to change the medium flow, pressure, temperature, liquid level and other process parameters of the final control element. Regulating valve is suitable for air, water, steam, oil and other media. Cage type double seat regulating valve is mainly used in large flow, high pressure drop occasions.
Characteristic
• Simple structure, compact, easy to install, maintenance, long service life;
• Body cavity S type flow channel and split wing design, medium pressure drop loss is small, circulation capacity is large, adjustable range is wide;
• Spool flow characteristic curve of high accuracy, balance type spool, unbalance force is small, allow large pressure difference, stable operation;
• The guiding area of the spool guiding part is large and has good seismic performance;
• Can use welding end and various pipe flange standards and flange sealing face type connection form, to meet various engineering needs and user requirements;
• A complete variety of valve body materials, gaskets and fillers can be reasonably selected according to the actual working conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions;
• Regulating valve can be equipped with our 101 series multi-spring pneumatic film actuator, or according to customer requirements with other brands of pneumatic, electric or hydraulic actuator.
