ROSS CONTROLS Double Valves for Clutch/rake Control SERPR Crossflow 5 Series

SERPR CROSSFLOW DOULE VLVES 5 SERIES WITH PRESSURE SWITCHES FOR EXTERNL MONITORIN KEY FETURES Designed to enable users to comply with current safety regulations Can be integrated with external monitoring systems to provide for lockout and inhibiting further machine operation until the controls system is reset Default to de-energized position upon fault condition uilt-in non-clogging silencers on Sizes, 8, and 0 Size and SERPR Crossflow valves with pressure switches (for external monitoring) are available from ¼ to ¾ port sizes. Externally monitored double valves provide feedback signals (via the pressure switches), which allows the main press controls, or separate monitoring device, The original application for these double valves was in the control of clutch/brake mechanisms on stamping presses, but they have found their way into many other critical applications such as alternative lockout systems for energy isolation, air cylinder press load-holding systems, as well as other Category - and - safety circuits. ROSS double valves are a vital part of any control-reliable fluid power control system. DESCRIPTION Page SERPR Crossflow Double Valves with or without Pressure Switches Size. -.

Valve Operation: oth solenoids must be energized simultaneously to shift the valve; maintained signal required to keep valve shifted. CUTION: If the monitor must be reset, electrical signals to both solenoids must be removed to prevent the machine controlled by the valve from immediately recycling and producing a potentially hazardous condition. VLVE OPERTION Conditions at Start: Inlet is closed to outlet by both valve elements and. Outlet is open to exhaust. Pressure signals at both switches SW and SW are exhausted. Contacts and of switches SW and SW are connected. Normal Operation: Simultaneously energizing both solenoids actuates both pilots and causes valve elements and to shift. Inlet is then connected to outlet via crossflow passages C and D. Exhaust is closed. Sensing pressure signals go to each pressure switch and become equal to inlet pressure. oth switches trip and now contacts and of switches SW and SW are connected instead of contacts and. SW SW Pb Pb C D SW Pa SW Pa Completion of Normal Cycle: Simultaneously de-energizing both solenoids returns the valve to the Conditions at Start described at left. Detecting a Malfunction: malfunction in the system or the valve itself could cause one valve element to be open and the other closed. ir then flows past the inlet poppet on valve element, into crossflow passage D, but is substantially blocked by the spool portion of element. The large size of the open exhaust passage past element keeps the pressure at the outlet port below % of inlet pressure. Full sensing air pressure from side goes to switch SW, and a reduced pressure goes to switch SW. This full pressure signal causes switch SW to trip. Switch SW, with a reduced pressure signal, does not trip. n external monitoring system can detect the malfunction by monitoring the condition of the switches SW and SW. The external monitoring system may then react accordingly by shutting down the power to the valve solenoids and any other components deemed necessary to stop the machine.

CUTIONS, WRNINS and STNDRD WRRNTY PRE-INSTLLTION or SERVICE. efore servicing a valve or other pneumatic component, be sure that all sources of energy are turned off, the entire pneumatic system is shut off and exhausted, and all power sources are locked out (ref: OSH 90.7, EN 07).. ll ROSS products, including service kits and parts, should be installed and/or serviced only by persons having training and experience with pneumatic equipment. ecause any installation can be tampered with or need servicing after installation, persons responsible for the safety of others or the care of equipment must check every installation on a regular basis and perform all necessary maintenance.. ll applicable instructions should be read and complied with before using any fluid power system in order to prevent harm to persons or equipment. In addition, overhauled or serviced valves must be functionally tested prior to installation and use. If you have any questions, call your nearest ROSS location listed on the cover of this document.. Each ROSS product should be used within its specification limits. In addition, use only ROSS parts to repair ROSS products. WRNIN: Failure to follow these directions can adversely affect the performance of the product or result in the potential for human injury or damage to property. FILTRTION and LURICTION 5. Dirt, scale, moisture, etc. are present in virtually every air system. lthough some valves are more tolerant of these contaminants than others, best performance will be realized if a filter is installed to clean the air supply, thus preventing contaminants from interfering with the proper performance of the equipment. ROSS recommends a filter with a 5-micron rating for normal applications. 6. ll standard ROSS filters and lubricators with polycarbonate plastic bowls are designed for compressed air applications only. Do not fail to use the metal bowl guard, where provided, to minimize danger from high pressure fragmentation in the event of bowl failure. Do not expose these products to certain fluids, such as alcohol or liquefied petroleum gas, as they can cause bowls to rupture, creating a combustible condition, hazardous leakage, and the potential for human injury or damage to property. Immediately replace a crazed, cracked, or deteriorated bowl. When bowl gets dirty, replace it or wipe it with a clean dry cloth. 7. Only use lubricants which are compatible with materials used in the valves and other components in the system. Normally, compatible lubricants are petroleum based oils with oxidation inhibitors, an aniline point between 80 F (8 C) and 0 F (0 C), and an ISO, or lighter, viscosity. void oils with phosphate type additives which can harm polyurethane components, potentially leading to valve failure which risks human injury, and/or damage to property. VOID INTKE/EXHUST RESTRICTION 8. Do not restrict the air flow in the supply line. To do so could reduce the pressure of the supply air below the minimum requirements for the valve and thereby cause erratic action. 9. Do not restrict a valve s exhaust port as this can adversely affect its operation. Exhaust silencers must be resistant to clogging and must have flow capacities at least as great as the exhaust capacities of the valves. Contamination of the silencer can result in reduced flow and increased back pressure. WRNIN: ROSS expressly disclaims all warranties and responsibility for any unsatisfactory performance or injuries caused by the use of the wrong type, wrong size, or an inadequately maintained silencer installed with a ROSS product. POWER PRESSES 0. Mechanical power presses and other potentially hazardous machinery using a pneumatically controlled clutch and brake mechanism must use a press control double valve with a monitoring device. double valve without a self-contained monitoring device should be used only in conjunction with a control system which assures monitoring of the valve. ll double valve installations involving hazardous applications should incorporate a monitoring system which inhibits further operation of the valve and machine in the event of a failure within the valve mechanism. ENERY ISOLTION/EMERENCY STOP. Per specifications and regulations, ROSS L-O-X and L-O-X with EEZ-ON operation products are defined as energy isolation devices, NOT S EMERENCY STOP DEVICES. ll products sold by ROSS CONTROLS are warranted for a one-year period [with the exception of all Filters, Regulators and Lubricators ( FRLs ) which are STNDRD WRRNTY warranted for a period of seven years] from the date of purchase to be free of defects in material and workmanship. ROSS obligation under this warranty is limited to repair or replacement of the product or refund of the purchase price paid solely at the discretion of ROSS and provided such product is returned to ROSS freight prepaid and upon examination by ROSS is found to be defective.
