Pneumatic pneumatic valve selection in the attachment

one Pneumatic pneumatic valve synopsis:
1. Pneumatic pneumatic valve is a kind of using compressed air driving operation of the pneumatic valve actuator, the opening and closing speed is relatively fast, often used for fast two position cutting, can also be used to adjust the flow, because it relies mainly on the gas source, under the condition of flammable and explosive of high practicability, can be used to control gas, liquid, oil and all kinds of corrosive medium.
2。 Change this accessory in pneumatic pneumatic valve, with different attachments, unable to achieve a variety of different control methods, users can need according to different pneumatic valve work, for the corresponding configuration.
3。 The main products are: pneumatic pneumatic valve pneumatic control pneumatic valve, pneumatic pneumatic valve, pneumatic valve, pneumatic pneumatic pneumatic brake valve, etc.



2. Pneumatic pneumatic valve sanlian pieces is introduced:
1. Pneumatic triple pieces is the most common type of pneumatic valve accessories, its function can be simply summarized as: filtration + stress + oil mist, which reduced pressure pneumatic valve is necessary attachments, no matter what is the function of pneumatic pneumatic valve, its function is to give a standard power supply pressure pneumatic pneumatic valve, standard value is 0. 4 to 0. 7MPa。
2。 Reduced pressure pneumatic valve is reduced by the inlet pressure to a certain outlet pressure, and rely on the energy of the medium itself, maintain stable outlet pressure pneumatic valve automatically. Two coupling ( The filter, vacuum pneumatic valve) Features: complete compressed air filter and pressure relief function; Triple parts ( Filter, vacuum pneumatic valve, oil mist) : complete compressed air filter and pressure relief function, and the air lubrication.



3. Pneumatic solenoid pneumatic valve product introduction:
1. Pneumatic electromagnetic valve, also called directional control pneumatic valve, applies only to open and close two pneumatic valve, pneumatic valve is a necessary configuration, solenoid pneumatic valve by excitation/demagnetization of pneumatic on/off control of pneumatic valve.
2。 Solenoid pneumatic valve, pneumatic valve is typically used for switch controlled by voltage signal source gas circuit switch, switch to control the pneumatic valve. Definition: solenoid pneumatic valve pneumatic valve operation is usually by controlling the motion process of pneumatic actuators to open and close.




4 pneumatic valve, pneumatic limit switch is introduced:

1, pneumatic limit, also known as the travel switch, also can call letter. It is in the automatic control system to detect the state of the pneumatic valve, field instruments to the pneumatic valve open or closed position to switch quantity ( Contact) The signal output, accepted by the programmable device or a computer search for sampling, confirm and executing the next program.
2, this product also can be used as the system of pneumatic valve interlock protection and remote alarm indicator. If you want to grasp two pneumatic valve pneumatic valve position state, limit switch is a valid configuration, pneumatic valve is used to indicate mechanical equipment and feedback of movement limit position of the electric switch.




5, pneumatic pneumatic valve positioner:

pneumatic positioner is the necessary configuration, pneumatic regulating pneumatic valve can be controlled by pneumatic valve positioner of the opening of the pneumatic valve in any position, it will pneumatic valve rod displacement signal as the input of the feedback signal, as set in the controller output signal, comparing, when there is deviation, change of its output signal to the actuator, the actuator, pneumatic valve rod displacement is established times and one to one correspondence relation between the controller output signal. Pneumatic pneumatic valve accessories and protect a pneumatic valve is a common used to protect pneumatic valve position after the expiration of a device.




6, choose pneumatic pneumatic valve regulation:

1, if there is a safety control regulation of pneumatic valve, pneumatic valve must also configure the electromagnetic force by electromagnetic pneumatic valve control pneumatic valve in pneumatic valve in the safety accident cases.
2, for the large capacity of cylinder, pneumatic valve, in order to speed up the action of pneumatic valve, pneumatic valve guide is also must be configured, guide the function of the pneumatic valve is driven by a small volume of gas signal to guide the pneumatic valve to switch of gas pipeline, the pneumatic cylinder valves have fast charge/discharge gas gas path, pneumatic valve guide to many species, this according to the specific needs of pneumatic pneumatic valves for selection.
3, if you want to master the pneumatic valve, pneumatic valve is to adjust then you must install the pneumatic valve opening transmitter, it can feedback the opening of the pneumatic valve in any position of the signal. Due to the needs of the process equipment, pneumatic valve may be normal open, slow, slow or open, normally closed, then you need to configure the pneumatic damper, by the size of the damper is the control volume, the pneumatic valve by adjusting to need movement speed.
