TheV230D01/V231D01self-operated (after-valve) pressure control valve is Composed of the control valve, actuator And a spring used for pressure setting. It is suitable for controlling after-valve Pressure in the pipes of non-corrosive liquids, gases and steams. When the after-valve pressure rises, the control Valve is closed.
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.

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, P2 is input to the lower 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 after-valve pressure. When the after-valve pressure P2 increases, the acting force of P2 that actson the top disc w ill 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 close towards 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 reduced, the flow resistance becomes higher and P2 is reduced to the set value. Likewise, when the after-valve pressure P2 decreases, the acting direction is reverse to the above. This is the working principle during the control of after-valve pressure. When it is necessary to change the set value of after-valve pressure P2, please adjust the adjusting nut.

JZF Series Multi Medium 2 Way Pneumatic Stainless Angle Valve With Plastic Actuator
Installation&MaintenanceÂ < /p>
1.Clean the pipes carefully from any residue,dribble or welding residue,to avoid any damage to the seal
2.To be installed as required,preferably with actuator in upright position
3.Connect the pipes according to the reference points(flow direction)
4.Before taking the valve apart,depressurize the media supply and pilot air supply piping system.
External air pilot,increase service life,maintenance-free.
Between overflow with self-adjusting slider gland,can improve sealing performance
Angle valve seat structure,allows a large flow(in particular with the general Compared thought the valve),a compact fast response.
Flow direction below the seat(direction A)
1.Valves with flow direction below the seat(direction A) ensure long services life.
2.Valves used for liquid media are waterhammer-free.
3.Valves with orifice DN15/DN20/DN25 are idea for the operating pressure of 0.3MPa
Â Valves with orifice DN32/DN40 are operated with double-acting actuators DN100
Â Valves with orifice DN50 are operated with double-acting actuator DN125
