<br>Select a VNA series valve when the operating fluid is an inert gas and needs to flow in both directions (port 1 (A) to port 2 (B) and port 2 (B) to port 1 (A)) or when using an air-hydro circuit. <br>Select a VNB series valve when the operating fluid is an inert gas and 1-directional flow (A to B) is acceptable, when using water or oil as the fluid, or when using for low vacuum.
<br>The min. operating pressure differential is 0.01 MPa because they are pilot operated 2-port valves. <br>Set the outlet pressure at least 0.01 MPa lower than the inlet pressure. <br>They cannot be used in vacuum applications.
<br>② The manifold base is made of stainless steel. <br>③ The max. operating pressure differential or other solenoid specifications do not satisfy the customer’s operating conditions.
<br>However, the suck back valve on its own is only capable of changing the volume by moving the diaphragm up and down, so it cannot stop the fluid. <br>Therefore, a stop valve (2-way valve) is required on the inlet side of the suck back valve.<br><br>
<br>It can be found here. <br>TL/TIL and TLM/TILM series tubing with the “-2S” part number suffix are the 2 m straight type, which does not curl.<br><br>
<br>Since the diaphragm type process pump is not a metering pump, the discharge rate per cycle varies. <br>The “discharge amount A per cycle” is the value obtained by flowing a specified amount of liquid from each process pump and dividing the amount by the number of operation cycles.<br><br>
<br>The 8.7 A on the product is the max. power current of the chiller, including all specification ranges. <br>Prepare an earth leakage breaker with a capacity of 10 A as listed in the HRS024 catalog. Set the current sensitivity of the earth leakage breaker to 30 mA.<br><br>
<br>For deionized water (pure water), replace all the water regularly because of the possibility of bacteria and algae generation inside the tank. <br>Take measures to prevent the generation of static electricity in the piping as well. <br>Refer to the “Specifications” section in the catalog for other applicable circulating fluids.
<br>Due to their Peltier type element, they are capable of both cooling and heating. <br>Note that HECR series thermo-cons can only be rack mounted. <br>Please refer to the catalog for details. <br>The HEC series catalog can be found here.
<br>Check that there is no leakage in the piping, including the customer’s device. If there is no leakage, supply circulating fluid according to section “3.5 Fill of circulating fluid” in the HRS series operation manual. <br>Depending on the problem, however, consider requesting maintenance from a maintenance company. <br>We can recommend service providers if needed.
<br>For details on resetting alarms, refer to section “5.18 (and 5.8) Accumulated Time Reset Function” in the HRS series operation manual, which can be found here. <br>Note that there is no alarm code “AL29” (fan motor maintenance) for water-cooled thermo-chillers. <br>Note 1) Every 30,000 hours for the HRS090 to 200 and the HRSH series
<br>Identify the model, and then refer to the catalog to determine the filtration rating. <br>Note that the nominal filtration accuracy is indicated on the side of sintered elements, and for bag filter elements, it is indicated on the tag at the top of the element.<br><br>
<br>Information on industrial filter selection can be found here.<br>The differences between the 2 are as follows. <br>Seal material: Select from NBR or FKM for the FQ1 series and NBR or fluororesin for the FGD series.<br>Housing material: Only stainless steel 304 is available for the FQ1 series.
SMC's VP300/500/700 series solenoid valve, offers high flow capacity and reduced power consumption (1.55W standard, 0.55W with power saving circuit). The series may be used as either a selector valve, or a divider valve. It is vacuum applicable up to –101.2kPa. Series VP3145/3165/3185 is a large size, 3 port solenoid valve with a rubber seal. It is possible to use the series in vacuum
