Product Desciption
The Introduction of Products 
P4
Because the independent pressure regulating valve has no external drive energy. Therefore, the operating force of the product is small, and it has the following characteristics:
1) Balanced spool structure, such as balanced single seat. Double spool balance type, sleeve balance type, etc.
2) Fast open flow characteristics, its spool is flat type.
3) Nominal size and valve body characteristics: DN20~100mm (or 125). The valve is provided with bellows, spool for a single seat (some manufacturers product DN20mm no bellows, spool is also a single seat); When the nominal diameter is greater than 100mm. There is no bellows in the valve cover, and the spool is double spool or sleeve structure.
4) Actuator type recommendation: set value ≤ 0.6mpa, choose thin film actuator; When the setting value is > 0.6mpa, choose the cylinder actuator.
5) The pressure setting value can be set continuously during operation.
6) After the valve pressure adjustment, the ratio of the valve pressure and valve pressure can be 10:1 ~ 10:8.
7) Rubber diaphragm type detection, implementation of high accuracy, sensitive action.
8) The use of pressure balance mechanism, so that the regulator sensitive response, accurate control.
Product installation and use
* When the valve is used in gas or low viscosity liquid medium, usually ZZY self-propelled pressure regulating valve is independent on the horizontal pipe, when the position space is not allowed to flip or tilt.
* When the valve is used in steam or high viscosity liquid medium, usually ZZY self-propelled pressure regulating valve is installed upside down on the horizontal pipe, and the condenser (steam with self-propelled) should be higher than the actuator of the pressure regulating valve and lower than the valve before and after taking over. The condenser should be filled with cold water before use, and then filled with water once every 3 months.
* The pressure taking point should be taken in the appropriate position of the pressure regulating valve, the pressure regulating before the valve should be more than 2 times the diameter of the pipe, and the pressure regulating after the valve should be more than 6 times the diameter of the pipe.
* In order to facilitate on-site maintenance and operation, there should be appropriate space around the pressure regulating valve.
* When the medium is clean gas or liquid, the valve filter can not be installed.
* Pressure regulating valve diameter is too large (DN≥100), there should be a fixed bracket.
* When confirming that the medium is clean, piece 3 can not be installed.
* The bypass valve (manual) can be omitted (we do not recommend) when the position is really not allowed.
* After the valve group, users can choose check valve, safety valve, etc.
* Self-operated valves can be smaller than the pipe diameter according to the calculated diameter, and globe valves, cut-off ball valves, bypass valves, filters can not be smaller than the pipe diameter.
* In order to ensure the maintenance and failure of the production can continue to run, it is best to set up a bypass system
* The filter in the system can be omitted if the process medium is clean and free of impurities.
* When there are impurities in the medium or use the self-propelled pressure regulating valve with a conductor, the filter should be installed to prevent blocking the pressure pipe or the conductor, jammed cylinder actuators and spool, etc.

The working principle of
1) The working principle of the rear pressure regulating valve of the self-operated valve is shown in Figure 3. Valve front pressure P1 through the valve core, seat throttling, into the valve back pressure P2. P2 through the pipeline input on the film chamber on the top plate, the force and the spring reaction force balance, determine the relative position of the valve core, seat, control valve pressure. As P2 increases, so does the force P2 exerts on the top disk. At this point, the force on the top plate is greater than the spring reaction force, so that the spool closed to the seat position. At this time, the flow area between the spool and the seat is reduced, the flow resistance becomes large, P2 is reduced, until the force on the top plate and the spring reaction force is balanced, so that P2 is reduced to the set value. Similarly, when P2 goes down. The direction of action is opposite to the above, and this is the working principle of the post-valve pressure regulation.
2) The working principle of the self-operated valve front pressure regulating valve is the same as the working principle of the valve back pressure regulation (see Figure 4), and attention should be paid to the reverse installation of the spool.
2) The working principle of the self-operated valve front pressure regulating valve is the same as the working principle of the valve back pressure regulation (see Figure 4), and attention should be paid to the reverse installation of the spool.
