Location of the filter pressure reducing valve in the piping
Thread Content
Dear colleagues: When installing instruments on pneumatic actuators, is the pressure reducing and filtering valve located in the position shown in the figure below?
There is no issue with the diagram; the pressure reducing valve is installed at the instrument air inlet to supply clean, pressure-stable air to the pneumatic actuators； It is recommended to install a switch-mounted ball valve upstream of the pressure reducing valve; this valve can be used to shut off the instrument air supply, facilitating subsequent replacement of the filter element and the pressure regulator.
Don’t pneumatic control valves and cylinders require a clean air supply? How to adjust the air pressure in the cylinder?
Pneumatic control lines, including instrument air along with filters and pressure reducing valves, are part of the standard configuration; we also install filters on the main pressure line (instrument air) to ensure a better operating environment for flow amplifiers and cylinders.
It is through this pressure-reducing filter valve that air is supplied to the actuator
