3 DUAL FLOW ALES Dual-Flow alves limit vacuum leakage in a system where some of the suction cups may not be in sealing contact with the work piece. Since vacuum flow is limited by a small orifice, DF valves are only recommended for non-porous parts or for slightly porous light weight parts. There are two main ways to apply DF valves: The first is to bring DF equipped suction cups into contact with the work and then turn on the vacuum source. Non-sealing cups will leak and cause the associated Dual-Flow valves to close to orifice flow only. 0, 5, 30mm Cups SIZING A ACUUM PUMP: From the table below, determine the orifice flow at your system s maximum vacuum operating level. Multiply this by the maximum number of non-sealing cups in the system. Select a pump that will give this total flow rate at the system vacuum level plus a factor of safety. The second way is to turn on the vacuum source to close all DF valves before the suction cups contact the work and then allow the DF orifice flow to establish vacuum within the cups once contact is made. In either case, part release is accomplished by removing the vacuum source and admitting atmospheric air to reopen the Dual-Flow valves. For a faster cycle time, use a blow-off pulse of compressed air to break the vacuum and release the part more quickly. FEMALE DUAL-FLOW ASSEMBLY WEIGHT 8 inhg (6 kpa) CONNECTION FITTING SUFFIX oz.

TRI-FLOW ALES Tri-Flow alves limit vacuum leakage in a system where some of the suction cups may not be in sealing contact with the work piece. Tri-Flow alves are a cross between Flow Sensor alves and Dual-Flow alves because they are fully open until the Flow Sensor section closes at the factory preset vacuum flow rate, then a bypass orifice meters vacuum flow to limit leakage to a manageable rate. Part release is accomplished by removing the vacuum source and admitting atmospheric air which will also reset any closed Tri-Flow alves to open position. For a faster cycle time, use a blow-off pulse of compressed air to break the vacuum and release the part more quickly. Tri-Flow alves can handle greater porosity flow than Dual-Flow alves due to the fact that they re initially held open. Another advantage is the Tri-Flow metering orifice is protected by an integral filter for greater tolerance of contamination. HOW TO ORDER: To order a cup assembled with a Tri-Flow alve, add suffix -8FTF to the cup part number. Cup fittings must have G /8 NPSF femal thread. Example: XP-B50N-8FTF The normal way to set up a vacuum system using Tri- Flow equipped suction cups is to bring them into contact with the work and then turn on the vacuum source. Nonsealing cups will leak and cause the associated Tri-Flow alve to close to orifice flow only. Tri-Flow alves on cups in sealing contact with the work will remain fully open to handle higher porosity flow rates (normal leakage through the part) than Dual-Flow alves can. For a system handling non-porous parts, operation can be as described above or the vacuum source may be turned on before the suction cups are in sealing contact with the work. Tri-Flow alves can pass vacuum flow through the metering orifice to establish vacuum within the suction cups after they are placed in sealing contact with the work and the Tri-Flow alves will reset to fully open. This feature is also convenient for use in vacuum holding fixtures. This capability is the only advantage that Tri-Flow alves have over Flow Sensor alves. For mid-to-high porosity parts, we recommend using Flow Sensor alves where the closing set point can be adjusted to suit the application. To order for use inline: TF8F-XX with G/8 NPS Female.

5 FLOW SENSOR ALES: PATENTED Flow Sensor alves (FS) are normally-open valves that snap closed when the factory preset flow rate is exceeded. Our FS is insensitive to acceleration forces and may be used in any physical orientation. System vacuum level has no effect on the FS set point, however, higher system vacuum levels will cause greater flow rates through a porous work place. Flow Sensor alves eliminate the problem of vacuum loss through non-working standard cups or through valved cups overhanging the work piece edge. These are especially useful where work piece size and orientation will vary. For maximum effective-ness, each suction cup in the system should be equipped with a Flow Sensor alve. When used with large bellows-style suction cups, the cup should be pressed against the work piece to collapse the bellows before turning on the vacuum. This prevents accidentally activating the FS by the high instantaneous flow rate caused by the bellows collapsing under vacuum. The FS will automatically reset when the vacuum is turned off for a short period of time. If desired, a pressure pulse can be used to back flow the FS and clean off the inlet filter. This blow-off pulse will reset the FS and will quickly release the work piece. The FSM version includes a monitor port where a vacuum sensor can be used to monitor whether the FS is open or closed. Flow Sensor alves may be manifold or located in-line rather than at the suction cup. Piping integrity is important since the FS will sense a fitting leak as easily as leakage at a suction cup. Wherever installed, a suitable filter must be used upstream of the FS. When used with EDCO fittings, a filter screen nests inside the fitting bore. The optimum flow rate set point is best determined by testing the porosity of sample work pieces with a flow meter using the same suction cup size and style as will be used in the actual system. Porosity of items such as corrugated board can vary greatly from lot to lot so it is important to find the most porous part to be handled by the system. A factor of safety must be added to the highest porosity test value to allow for variations in work piece porosity, system vacuum level, increased leakage due to wear and other factors. For porous work pieces such as paper and corrugated cases, the factor of safety probably should be in the 50% range. For non-porous work pieces such as plastic or metal, the factor of safety may be reduced. It is necessary to size the vacuum pump to have enough capacity to close all Flow Sensor alves where cups are not sealed against a work piece plus the total porosity flow through the sealed cups. EDCO air powered multi-stage vacuum pumps are ideally suited since they produce large vacuum flow rates at low vacuum levels (0-0 in-hg) and can provide the flow necessary to close a large number of Flow Sensor alves. The FS is a larger / NPT version that is for use with larger suction cups but is functionally the same as FS 8. The FS 0 is for use with 5mm and smaller suction cups but is functionally the same as an FS 8. HOW TO ORDER: FS8 + FLOWRATE (SCFM x 0) + FITTING SIZE. EXAMPLES: FS is a standard FS that is set to close when a flow rate exceeds 0.9 SCFM and includes a size 50 cup fitting and filter screen. FS8-6-8M is an FS set to close when flow rate exceeds 0.6 SCFM and includes a /8 NPT male fitting and filter screen for inline mounting. AAILABLE FLOWRATE SETPOINTS: FS 0 = 0. to 0.6 SCFM in 0. increments FS 8 = 0.3 to.3 SCFM in 0. increments FS = 0.5 to 6.0 SCFM in 0. increments Conversion: SCFM = 8.3 NI /m 0 EDCO USA. :5

7 RELEASE CHECK RC8A The RC8A employs a normally closed valve to seal against pump vacuum without leaking. When a compressed air supply is applied, the release valve shifts open at only 5 psi (0.3 bar) so that a full-flow burst of air can quickly dissipate (blow-off) system vacuum. Once shifted, the valve doesn t try to close, but remains open. Once the compressed air source is removed it automatically resets to a closed position. The RC8A should be used for high-flow vacuum release applications such as those involving vacuum reservoirs or larger single-stage or multi-stage vacuum pumps. Competitive products are simply check valves with a 30-0 psi (-3 bar) cracking pressure. The high cracking pressure is necessary to insure a tight seal against vacuum developed by the pump. When a compressed air supply is applied to open the valve for blow-off, the internal spring immediately tries to close the valve as soon as flow begins. This has the effect of subtracting the valve cracking pressure from the blow-off air pressure. Because of this these systems normally have to operate above 50 psi (3.3 bar), which wastes compressed air. 50 psi Maximum Pressure Weight:.07 lbs.

8 ACUUM CHECK The acuum Check valve is designed to prevent the reverse flow of ambient air into a vacuum system. acuum Check valves are used to hold vacuum downstream whenever the vacuum source is removed or lost. Internally, a normally closed valve allows vacuum flow in the pump direction, but seals off when vacuum flow ceases. When a vacuum check valve is used in a system, some provision must be made to release the trapped vacuum in order to release the work piece. The RC8 and RC8-00 release check valves are designed for this purpose. One application for the acuum Check valves is for energy saver circuits using a vacuum storage tank to accumulate and store vacuum for highvolume, short duration, flow rate requirements. dropped if the system s vacuum source is lost. The vacuum trapped by the acuum Check will eventually leak down. The rate at which the vacuum diminishes will depend on the condition of all the components in the vacuum system. To increase the time delay interval, a volume chamber can be added to the auxiliary port. If the volume chamber is equal to twice the cup internal volume, the time delay interval will be approximately tripled, and so forth. The C8 should be used with cup diameters of 50mm and smaller. The C should be used with cup diameters of 75mm and larger that are available with G/ NPS female fittings [.] More commonly, a vacuum check valve with release check valve would be used with a single suction cup so a nonporous, high value work piece would not be immediately C8 0.8 [.].80 [5.7].60 [0.6].36 [3.5] 0.8 [.6] THRU PLACES 0.63 [6] acuum Source 0.8 [.6] 0.99 [5.].6 [9.5] 0.8 [.] A 0.8 [.] A 0.7 [.9].8 [3.5] Weight:.5 lbs.

9 ACUUM CHECK WITH RELEASE CHECK The acuum Check valve with Release Check is used with a single suction cup so a non-porous, high value work piece won t be immediately dropped if the system vacuum source is lost. The vacuum trapped by the acuum Check will eventually leak down. The rate at which the vacuum diminishes will depend on the condition of all the components in the vacuum system. To increase the time delay interval, a volume chamber can be added to the auxiliary port. If the volume of the chamber is twice the internal cup volume, the time delay interval will be approximately tripled, and so forth. See Page :7 for RC00A description.
