<br>Note 1) The discharge pressure can be set for HRSH series thermo-chillers. <br>Note 2) The pressure cannot be displayed for HRSE series thermo-chillers.
<br>Check that there is no restriction in the piping, including the customer’s device. <br>If there is restriction, thicken the piping or relieve the circulating fluid flow rate with a bypass piping set. <br>Depending on the problem, however, consider requesting maintenance from a maintenance company. <br>We can recommend service providers if needed.
<br>Alarm code “AL28” (pump maintenance) will be activated every 20,000 hours (every 8000 hours for option “T” and the HRS050/060) of operation. <br>Consider requesting maintenance from a maintenance company. <br>We can recommend service providers if needed.
<br>Even if there is no leakage, replacement of the mechanical seal is recommended. <br>The mechanical seal can be replaced up to 2 times. If foreign matter enters the circulating fluid, leakage may occur earlier. <br>For protection of the mechanical seal pump, we recommend the installation of a particle filter.
<br>When replacing, follow the replacement procedure in the operation manual and the element replacement procedure (published on the SMC website). <br>The FGD series catalog can be found here. <br>The FQ1 series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=industrial-filters&fa_id=10645
<br>Note) Single-side air driving of SMC hydraulic cylinders is possible, but the increased pressure will drop if air gets inside the air-hydro booster, so be sure to drive both sides with oil whenever possible.<br><br>
<br>Refer to the following formulas for converting the displayed values. <br>sonic conductance C x 5 = effective area S[mm2]<br>Cv x 18 ≈ effective area S[mm2]<br><br>

<br>This part number includes an O-ring and a tension bolt for connection.<br>If valve size 2 (VV72□) is used, the AXT512-1A-□-□ manifold block assembly is needed. This part number includes an O-ring and a bracket.<br>For details, refer to the manifold exploded view in the catalog.<br>Note) The gasket for use between the valve and the manifold is attached to the valve.
<br>The main points of comparison between the new and old type are as follows.<br>① The pilot valve has been changed. (New and old pilot valves are not interchangeable.)<br>② The low-wattage type (0.4 W) is now the standard specification.<br>③ The new valves are manifold mountable.
<br>Please refer to the links below for details on the main special order options.<br>For other special order requests, please contact your local SMC sales representative.<br>The VFS3000 series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=directional-control-valves&fa_id=10866
<br>Products without sub-plates can also be mounted on a manifold.<br><br>Ex.) With a sub-plate: VFS2100-5FZ-01, Without a sub-plate: VFS2100-5FZ<br>With a sub-plate: VFR3110-1DZ-02, Without a sub-plate: VFR3110-1DZ
<br>If the solenoid valve series is the same (e.g.,, VFS3000 series, base mounted, same plug-in type), the solenoid valve mounting surface will have the same shape.<br>Therefore, the solenoid valve can be replaced within the series.<br>However, in this case, the circuit function will also change after mounting.<br>Note) Check the connection of lead wires separately.
<br><br>Rated, 24 VDC: 20.4 VDC to 26.4 VDC<br>Rated, 100 VAC: 85 VAC to 110 VAC<br>Rated, 200 VAC: 170 VAC to 220 VAC
<br>The SY series plug-in type 5-port valve, for example, is a good choice depending on the application.<br>(Select the quick response type with a metal seal.)
<br>The new VQZ series consumes less power due to the changing of the pilot valve. The old and new valves are generally interchangeable, but the (L type plug/M type plug) connector is not interchangeable.<br>The standard power consumption of new VQZ series valves is now only 0.35 W (DC), so there is no low-wattage type (symbol “Y”) as there was for old VQZ series valves.
