Summary
The*0D*4Y/*0D*4R self-operated differential pressure control valve is composed of the control valveï¼Œactuator and a spring used for pressure settingã€‚
It is suitable for controling differential pressure in the pipes of non-crrosive liquids gases and steams. when the diferential pressure rises, the control valve is opened
The main features are as follows:
1.It has the pressure balancing Function with high sensitivity.
2.Low noise, reliable performance free of maintenance
3.The standard modular design is adopted.
4.Various combined controls can be carried out through the assemblies Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

Working principle
After throttling by the plug and seat, the before-valve pressure P1 of the process medium is changed into the after-valve pressure P2. Through the control pipeline, P1 is to the upper diaphragm chamber of the actuator and acts on the top disc.
The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly.
At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure.
When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut.Â Â
