What are the advantages of self-operated control valves?

Self-operated control valve is a new type of control valve that has become popular in recent years. It does not require manual adjustment, nor external (such as: electric, pneumatic) power adjustment. It is precisely because of this characteristic that it is deeply loved and respected by people in the industry. The use of self-operated regulating valve is not only convenient and simple, but also saves resources.

Self-operated control valve is a new type of control valve. Compared with the manual control valve, its advantage is that it can be adjusted automatically; compared with the electric control valve, its advantage is that it does not require external power. Application practice has proved that in closed water circulation systems (such as hot water heating systems, air conditioning and chilled water systems), the correct use of this kind of valve can easily realize the flow distribution of the system; it can realize the dynamic balance of the system; it can simplify the system Debugging work; can stabilize the working state of the pump, etc.

Self-operated pressure control valve (with condenser) ZY-type self-operated pressure control valve (self-operated pressure control valve) does not require additional energy, uses the energy of the adjusted medium as a power source, introduces an actuator to control the position of the spool, and changes the position of the spool at both ends. The pressure difference and flow rate make the pressure before the valve (or after the valve) stable. It has the advantages of sensitive action, good sealing, low pressure set point wave power, etc. The self-operated pressure control valve is widely used in the automatic control of gas, liquid and steam medium pressure reduction and pressure stabilization or pressure relief and pressure stabilization.

The self-type pressure control valve has three structures: single seat (ZZYP), sleeve (ZZYM), and double seat (ZZYN); the actuator has two kinds of diaphragm type and piston type; the function type has pressure regulator after pressure reducing valve (B Type) and pressure relief valve front pressure adjustment (K type). The nominal pressure grade of the product has the range of DN15~250; the leakage level has three levels of II, IV and VI; the flow characteristic is quick opening; the pressure section adjustment is from 15 to 2500Kpa. It can be combined as needed to meet the user's working conditions.

Advantages of self-operated regulating valve
(1) The adjustment accuracy is high.
(2) The detection accuracy of the actuator is high.
(3) The valve is sensitive and easy to operate.
(4) The regulating valve has fast response speed and control.
(5) It can work without electricity and gas, saving energy.

The simple structure of the self-operated regulating valve has both advantages and disadvantages, so we must choose the regulating valve according to our own needs, so that we can play the function of the regulating valve.
