What are the classifications of electronic pneumatic regulators? How do they distinguish between choices? Of course, there is some data to choose from. The adjustment structure is actually very simple, as for the single-seat, sleeve this is selected according to the flow size, the user in the selection process as long as you know about the line, the detailed core technology is to choose the structure and caliber through professional software and calculation formula technology. The following is the selection of electronic pneumatic regulators for reference.
Here is the content list:
l Selection according to use requirements
l Selection based on safety
l Select according to the application domain
Electronic pneumatic regulator by the valve core and valve body (including seat) two parts, according to different use requirements have different structural forms, pneumatic film control valve is mainly through single seat valve, double-seat control valve and high-pressure Angle type control valve.
Atmospheric pressure difference occasions, the choice of fluid pressure imbalance type top oriented one-way regulating valve, is a small volume, simple structure but can adapt to harsh working conditions of the single-seat electronic pneumatic regulator. Due to the use of an unbalanced spool, and the small design of multi-spring film actuator combination, appearance greatly reduced. Because there is no fluid pressure balance structure, the series of regulating valves are especially suitable for all kinds of fluids.
Selection based on safety
The regulating valve of the electronic pneumatic regulator has two forms: the open valve and the closed valve. According to the safety and use requirements of different production processes, when the signal pressure is interrupted, the regulating valve is in the open or closed position, and the harm caused to the process production is determined by the size. If the valve is in the closed position when the harm is small, the gas valve is selected, the signal pressure is interrupted, the regulating valve is in the closed position, otherwise, the gas closed valve is selected.
Nitv electric proportional valve can use electrical signals to adjust the air pressure, through the adjustment of air pressure continuous stepless regulation, remote control and program control, greatly facilitate the operation of personnel. For continuous or stepless regulation of air pressure working environment, especially suitable for the electric proportional valve to play a role. So, what are the characteristics of NITV series electric proportional valves? Nitv series electric proportional valves are sensitive and stable. NITV series electric proportional valves can choose from either analog output (DC1-5V) or switched output (NPN/PNP). NITV series electric proportional valves are available in three models: NITV 1000/2000/3000 series. Nitv series electric proportional valve with cable plug directly to 3M, no cable plug.
