Compressor
Vacuum Generator VK SeriesComplex Ejector with many selectable combinations.
• The coil of vacuum generating valve and vacuum release is modified in order to achieve better durability, reliability and less electric comsumption.• Two types of vacuum switches, the pressure sensor type with LED digital display and the low-cost, easy to use mechanical type, are available to choose from.• An LED display is used for LED digital pressure sensor to enhance visibility.• Two types of vacuum switch − two-point output and one-point output with analog output (Conventional model was one-point output type.) − are available depending on
the desired application.• Solenoid current consumption of 24VDC spec. is reduced from 1.2W (conventional type) to 0.8W.• Solenoid current consumption of 100VAC spec. is reduced from 1.2VA (conventional type) to 1VA.• Push-button system of lock type is standardized (Conventional model is manual (button)).• Installation of Manifold is compatible to conventional type. Combinational use of new type and conventional type does not affect its performance.

Notes on filling in the specification order form(1) As for model designation 1) and 2) in item 2 above, the space (5) for Vacuum port
is entered 00, a side port-based specification, which accordingly does not show the fitting size. The fitting size will be indicated in 3. specification order form. Therefore, there may be a difference in format style between 2. the model designation form. and 3. specification order form 3. as to the Vacum port space (5).
(2) Station numbers are arranged in serial order as St 1, St 2, …St 10 form the L side towerd R side. To confirm the positions of the L and R sides, see the Manifold Type reference chart on page ???.
(3) If the top-mounting units for St 1, St 2 and St 3 are of the same specifications as in the above example of specification order form, fill up the St 1 space (uppermost) only, while entering St 1 in each of the St 2 and St 3 grids on the Config. (port pos.) column (1). (For example, if the top-mounting unit for St 6 happens to be the same model as that of St 1, enter St 1 in St 6's grid on the Config. (port pos.) column (1)). On the right-hand edge column are grids to enter the number of common units for respective St numbers. Remember to fill in these grids as a verification of the number of common units per manifold.With respect to solenoid valves, we have, in principle, unified working voltage. Therefore, we cannot provide the manifold type in different working voltages such as 24VDC and 100VAC. However, we can provide either N.O. or N.C. type if the two types are of the same working voltage, so it is possible to choose one as with the case of solenoid valve type (8).

Common Safety Instructions for Vacuum Generator VG and VK TypesBe sure to read the following instructions before selecting and using the PISCO devices. Also read the detailed instructions for individual series.
: 1. For the operation of the valve, make certain that the leakage current is less than 1mA. Leakage current larger than that may cause malfunction.2. The Vacuum Generator with hold function or check valve function permits some vacuum leakage, so provide an appropriate safety means where vacuum
must be held for a long time.3. Long continuous power supply to the valve may raise the temperature of the coil. Heat may cause burns or affect the surrounding equipment adversely.
Consult PISCO about such applications.
Warnings
: 1. Do not give excessive tension or bending to the valve lead wire. Disconnection or damage to the connector may result.2. In respect to manifold specifications, performance deterioration or adverse effects may possibly be produced on the vacuum ports of other stations
depending on the number of manifold series used and/or combinations of installed units. Discretion is therefore to be used in this respect. Consult us if problems arise.
3. Compressed air contains a variety of foreign matter (such as water, oxidized oils, and mineral tar among others). Since foreign matter substantially reduces the performance of this equipment, air quality should be enhanced by dehumidification via after-coolers or dryers.
4. Do not use lubricators.5. Since pipe rust cause malfunctions, a filter finer than 5µm should be used.6. Do not use this equipment near corrosive and/or flammable gases. Do not use this equipment for the handling of fluids.7. Do not activate blow-off solenoid valve when a vacuum has been generated.8. When replacing vacuum port cartridge joints, first remove any foreign matter clinging to them and the surrounding areas, then firmly insert pins into
joints.9. For handing and setting of vacuum switch, please read instruction manual carefully.
10. For adhustment of vacuum breaking (blow-off) air flow or blow-off time of air-timer type blow-off valve of VK, please read the following instructions carefully.
Cautions
■ Adjusting blow-off air flowBlow-off air flow is reduced when the flow adjusting needle is turned clockwise (to right), while it inceases when turned counterclockwise (to left).* After adjusting the blow-off air flow, please make sure to tighten the lock nut to keep the setting by following ① & ②.① Without moving the needle, finger-tighten the lock nut clockwise until it hits needle-guide. Then tighten the nut by turning 20 ~ 30° more by using
proper tool.② Please be careful not damage the thread by over tightening.
VG VK
■ Blow-off time adjustment of Air timer type blow-off valve of VKBlow-off air time is becomes long when the flow adjusting needle is turned clockwise (to right), while it becomes short by turning the needle counterclockwise (to left).

Common Safety Instructions for Products Listed in This ManualPISCO products are designed and manufactured for use with general industrial machinery and equipment. Therefore be sure to observe the following safety instructions:
: 1. Avoid the following uses for PISCO devices:(1) Use under conditions not specified for the device(2) Use in any outdoor environment(3) Use in locations where the device is exposed to excessive vibration or shocks(4) Use in locations where the device is exposed to any corrosive gas, inflammable gas, chemicals, seawater, or vapor.* Certain PISCO devices, however, can be used in environments as described above. Therefore check on the specifications for the use of individual
devices.2. Do not disassemble or remodel the PISCO devices in such a way as may affect the basic structure, performance or function of them.3. Never touch the release ring of the Quick-Fitting Joint when there is pressure working on it. Touching may release the ring, which in turn may cause the
tube to fall out.4. Avoid too frequent switching of air pressure. Otherwise the device body may heat up to cause burns on you.5. Do not allow tension, twist or bending forces to act on the joints. Undue forces may damage the joint body.6. For applications in which the threaded side or the tube connection side is subject to vibration, use Rotary Joints, High Rotary Joints or Multi-Circuit Rotary
Blocks only. Swinging or rotation may damage the joint body.7. For applications with hot water of 60°C (140°F) or above or thermal oil, use no other joints than Die Temperature Control Fitting, Tube Fitting Stainless
SUS316, Tube Fitting Stainless SUS316 Compression Fitting, and All Brass Compression Fitting. Heat or hydolysis may damage the joint body.8. For applications in which the scattering of static electricity or charging must be prevented, use no other joints than EG Joints. Static electricity may cause
system malfunction or trouble.9. Never use joint other than Tube Fitting Spatter or Tube Fitting Brass where they are exposed to spatter. Otherwise can cause fire.10. Carry out maintenance and checks of equipment only after turning power off, shutting fluid off and making certain that the pressure in the piping has
dropped to zero. Please conduct maintenance after confirming following points. (1) Make sure that maintenance is safe for all the systems involving PISCO products. (2) When re-activate equipment after maintenance, make sure safety measures against fly-out are taken and re-activate equipment with care.(3) Please secure space for maintenance when the circuit is designed.
11. When the fluid is admitted to the equipment and if there is a possibility to cause damage to it due to leakage, conduct safety measures such as protect cover beforehand.
Warning
: 1. In installing the piping, be sure to remove dust or drainage from within the piping. Dust or drainage left unremoved may enter other equipment, thus causing troubles.
2. When using an ultrasoft tube to connect to a Quick-Fitting Joint, be sure to use an insert ring in the bore of the tube. Otherwise the tube may fall out to cause leakage.
3. When you use tubes of brands other than ours, be sure to confirm that the outside diameter of the tubes satisfies the tolerance specified Table 1.
