Directional Control Air Valves & Accessories

S.O.S. CYLINDER CONTROLFEATURES:• Compact modular construction• Safely neutralizes pneumatic cylindermovement if emergency stop is initiated• Exhausts cylinder air when supplypressure is exhausted• “Pre-charges” system when air is appliedto prevent cylinder slamming• Bypassed to normal 4-way valve operationwhen system is not being exhausted or pressurized• Single or dual interposed regulation available• Automotive interfaceAIR FLOW DATA:Model Port Size Average CvAU-2 1/2 NPT 4.0AU-2 3/4 NPT 4.4ORDERING INFORMATION:Horizontal Cylinder ApplicationsTo order an S.O.S. Control Valve; select the following:1. Model Number2. Pipe Size3. Operator Style4. Voltage/HertzThe SOS bypass valve is an interface between an automotive 250 size valve (AU-2)and base. The SOS valve works in conjunction with the 4-way 3-position (“B” spool)power valve to provide 3-position valve function plus the ability to render the valveand cylinder combination safe for maintenance.The 3-position power valve enables the operator to stop cylinder movement by deenergizingboth solenoids on the power valve, causing the spool to center, thusblocking all valve ports. This function is useful during emergency stop procedures.By bleeding the trapped air between the valve and the cylinder piston (both sides),the SOS bypass valve renders the “charged” air cylinder safe. This function isinitiated by exhausting supply pressure to the power valve.The bypass valve also allows both sides of the cylinder to “precharge”simultaneously when supply pressure is reapplied to the power valve. After thecylinder is filled with equal pressure on both piston sides, the bypass valve disables,and the power valve takes command. This cylinder precharging method allowsthe flow controls to properly operate on the first cycle to prevent cylinder slamming.EXAMPLE:AU2 - 10007 - 37F - 120VHORIZONTAL CYLINDER OPERATIONALKONLoc-Master ®(optional)VERTICAL CYLINDER OPERATIONVoltage:Specify 120V AC or 24 VDCALKONLoc-Master ®(optional)NOTE: Vertical Cylinder Applications,Add AU2-AMR-O Regulator and 90A50125 Kit.73SeriesOperator:37F - Solenoid w/ 5 Pin Mini Connector (Ford Wired)37C - Solenoid w/ 5 Pin Mini Connector (Chrysler Wired)57F - Solenoid w/ 5 Pin Micro Connector (Ford Wired)57C - Solenoid w/ 5 Pin Micro Connector (Chrysler Wired)03 - Air Pilot OperatedModel/Pipe Size:10007 = 1/2 NPT10008 = 3/4 NPT10009 = Valve Assembly Less Base
