Parker 2 Way Proportional Valve And Servo Valves D1FVE02BCVF0A41

Parker Proportional Valve Features

The input signal of Parker proportional valve increases, the solenoid pilot valve 1 for gas supply is reversed, and the solenoid pilot valve 7 for exhaust is in the reset state, then the gas supply pressure enters the pilot chamber 5 from the SUP port through valve 1, the pressure of the pilot chamber rises, the gas pressure acts on the upper part of the diaphragm 2, then the gas supply valve core 4 connected with the diaphragm 2 is opened, and the exhaust valve core 3 is closed, and the output pressure is generated. This output pressure is fed back to control loop 8 through pressure sensor 6. Here, a quick comparison with the target value is corrected until the output pressure is proportional to the input signal, thus obtaining a change in the output pressure proportional to the change in the input signal. Because there is no nozzle baffle mechanism, the valve is not sensitive to impurities and has high reliability. peculiarity

1) It can realize the endless adjustment of pressure and speed, and avoid the impact phenomenon when the switching valve is reversed.

2) Can achieve remote control and program control.

3) Compared with intermittent control, the system is simplified and the components are greatly reduced.

4) Compared with the hydraulic proportional valve, small size, light weight, simple structure, low cost, but the response speed is much slower than the hydraulic system, and it is more sensitive to load changes.

5) Small power, less heat, low noise.

6) There will be no fire, and the effect of temperature change is small.

Proportional valves include thermal compensation proportional valves, non-thermal compensation proportional valves, OEM systems - proportional. Model EPC is a DC driven normally closed valve that includes an elastic seat to provide airtight closure. Wide flow coefficient (Cv) can be used for flow or pressure control.

Model EPC offers integrated compression fittings for in-line installation or as a manifold mounted version to allow design and user flexibility, also available in OEM-scale configurations: proportional control valves are designed for closed circulation or pressure control systems. When connected to flow or pressure sensors and proportional electronic controllers, Parker EPC valves provide stable and accurate control of gas flow rate or pressure. To increase design and user flexibility, it is also possible to OEM the volume and number of devices.
