The regulating valve is one of the important links in the automation of the production process. It is driven by compressed air or electric power, receives the signal sent from the regulating instrument, changes the control parameters such as the pressure, temperature, and flow of the medium, so that the production resettlement requirements are fulfilled and the production process is realized. Automation.

The regulating valve is divided into self-operated regulating valve according to the driving mode, that is, the energy of the regulated medium is used to realize the automatic adjustment of pressure, temperature and flow rate, such as self-operated pressure regulating valve, self-operated temperature regulating valve and self-operated differential pressure regulating valve, Self-operated micro pressure control valve. Pneumatic control valve powered by compressed air. Electric control valve, powered by electricity. Electro-hydraulic control valve, manual control valve, intelligent control valve. In accordance with the upper valve cover is divided into ordinary type, heat dissipation, long neck type, bellows sealed type. In accordance with the flow characteristics are divided into straight lines, equal percentages, parabolic, fast open. In accordance with the form of movement of the spool is divided into straight stroke, angular stroke. According to the adjustment form is divided into adjustment type, cut-off type, adjust the cut-off type. According to the spool shape is divided into flat spool, spool spool, window spool, spool spool, multi-stage spool, eccentric spool, butterfly spool, spherical spool. Commonly used single-seat control valve, two seat control valve, sleeve control valve, angle control valve, three-way control valve.

The development of control valves has been rapid, and new varieties have been developed based on new process requirements, such as intelligent control valves, ultra-small flow control valves and so on.
