What is the advantage of self-reliance type pneumatic control valve?

Self-reliance type pneumatic control valve is popular in recent years a new type of pneumatic control valve, it does not need to manually adjust, also do not need external ( Such as: electric and pneumatic) Dynamic adjustment. Because of this feature makes it was deeply loved by people in the industry and respected. Use self type pneumatic control valve not only convenient and simple, and can save resources. Below small make up take you to learn about the advantages and disadvantages of self-reliance type pneumatic control valve! Self-reliance type pneumatic control valve is a new pneumatic control valve type. Compared with the manual pneumatic control valve, its advantage is able to automatically adjust; Relative to the electric pneumatic valve, its advantage is not need external motivation. The application practice proved that the closed water circulation system ( Such as hot water heating system, air conditioning chilled water system) The proper use of the valve, the flow distribution can be easily implemented system; Can realize the dynamic equilibrium of system; Can greatly simplify the system debugging work; Fix the pump working condition, etc. Self-reliance type pneumatic pressure regulator ( With condenser) ZY self-reliance type pneumatic pressure regulator ( Self-reliance type pressure control valve) Without additional energy, use energy modulated medium itself as the source of power, introducing device, control valve core position change at the ends of the bending differential pressure and flow, make the valve before ( Or after valve) Pressure stability. Action sensitive, good sealing, the advantages of small pressure set point wave power, self-reliance type pressure control valve is widely used in gas, liquid and steam medium pressure regulated or pressure regulator, automatic control. Since the pressure control valve have single-seat ( ZZYP) And the sleeve ( ZZYM) , two-seat ( ZZYN) Three kinds of structure; A diaphragm, two piston actuator; Function type have after decompression with valve pressure regulation ( B) And pressure relief valve pressure regulation (before K type) 。 Product nominal pressure rating, and valve body diameter range DN15 ~ 250; Leakage level class II, IV and VI three gears; Flow characteristic of quick opening; Pressure block adjustment from 15 to 2500 kpa. Can be combined according to the need to satisfy the working condition of the user requirements. The advantages of self-reliance type pneumatic control valve ( 1) High precision of adjustment. （ 2) High precision of the actuator. （ 3) Valve action sensitive, easy to operate. （ 4) Pneumatic - valve response speed and control precision. （ 5) Can work under no electric airless condition, save the energy. Self-reliance type pneumatic control valve has the advantages of simple structure, so that we in for routine maintenance workload will be a little less, the pressure set point can be a wide range of adjustment, for the convenience of consumers within the range set for continuous adjustment, pressure balance mechanism in the valve, pneumatic control valve in order to make responsive, accurate control, and can adjust low corrosive medium, or as water, oil, air and other liquid medium, and non-corrosive gases below 350 degrees Celsius. Self-reliance type pneumatic control valve can also adjust the medium of high temperature, but must be equipped with a condenser, isolation tube such as attachments, only in this way can ensure self-reliance type pneumatic - valve to a safe and effective for high temperature medium. Valve after medium dosage reduction, no dosage, or intermittent dosage, pneumatic control valve will be leaked, this is self-reliance type pneumatic - valve structure simple, the negative effects of, but it doesn't matter, we are usually continuous use of medium will give preference to self-reliance type pneumatic control valve. Self-reliance type pneumatic - valve structure simple has both advantages and disadvantages as well, so we should choose according to their needs of pneumatic control valve, so we can play the effect of pneumatic control valve.
