<br>The orifice on the pressurized side of VXV series valves is half the diameter of the orifice on the vacuum side. For vacuum side orifices, the orifice diameters are the same for both VXV and VX3 series valves.

<br>In addition, you can change the direction by removing the terminal block. Insert a small flathead screwdriver into the notch in the bottom of the terminal block to remove it, and then reattach it facing the desired direction.

<br>So a DIN connector with the cable entry facing downward can be changed to face upward by changing the orientation 180°.

<br>On the other hand, for air operated valves, the main valve is operated by switching between supplying and exhausting air to/from the pilot port using another 3-port valve, etc. (For VN□ series air operated valves, the fluid temperature can be up to 99°C depending on the model.)

<br>Please consider changing to the grommet type (option “G”) (for the VNA and VNB only) or the DIN terminal type (option “D”).

<br>Contact SMC for details.

<br>As for the double acting type, it is switched by the ON/OFF of both the PA and PB ports.

<br>A checklist of the materials used for each process pump and the compatibility of various fluids is provided. Please read carefully before selecting a fluid.

<br>When using with an HRS series thermo-chiller, use tap water to create a 4:1 ratio of water to solution.

<br>Note) HED series chemical thermo-cons allow for the direct temperature control of chemical solutions.

<br>Check for leaks and regularly supply and replace the water.

<br>Refer to the water tank examples in the “Cooling Capacity Calculation” section in the HR□ catalog, and prepare an immersion type heat exchanger.

<br>If the temperature difference between the heat value of the object to be cooled and the circulating fluid is calculated backward, the required single pipe length is approx. several to several tens of meters. However, SMC does not sell immersion heat exchangers. Contact a manufacturer of immersion heat exchangers for more information.

<br>If it is lost or damaged, it can be ordered as an individual part.

<br>In addition, if the pressure drop reaches 0.1 MPa, even if the flow rate is currently sufficient, replace the element.

<br>The FG□ series element replacement procedure can be found here.

<br>The absolute filtration accuracy is generally indicated by the filtration efficiency (%). The nominal filtration accuracy, on the other hand, is not generally or industrially recognized and is determined by different standards depending on the manufacturer or filter medium.

<br>The part number is “130184A,” and 2 mounting screws are included in the package.

<br>However, the rubber material used for parts other than the diaphragm is NBR.
