The effect of self-reliance type pneumatic control valve and its advantages

Self-reliance type pneumatic - valve on within the medium flows through the valve's own pressure, temperature, as energy drive valve work automatically, do not need the power converter and secondary instrument. Self-reliance type pneumatic control valve using valve the output feedback signal ( Pressure, differential pressure, temperature) Through signal to the actuator driven disc change of valve opening, to achieve the purpose of regulating pressure, flow, temperature. Self-reliance type pneumatic control valve is a new type pneumatic control valve types themselves. 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.
