Typicalapplications include freestanding and wall-hung boilersfor residential hydronic heating, commercial cookingappliances, and commercial tumbler dryers.Figure 1: GM-7000 Series Multi-function GasControl ValveFeatures and Benefits❑ Class A and Class B Singleor Twin Solenoids❑ Optional Direct-acting orLever-acting PressureRegulation❑ Optional Manual FlowAdjustment❑ Multiple Operating Voltages❑ Approved WorldwideProvides flexible options for residential and lightindustrial marketsOffers alternative regulator adjustment control forspace-restrictive applicationsProvides field-adjustable flow control for rangeratedapplicationsProvides the flexibility to suit worldwide marketrequirementsBroadens applications to include global markets© 1998 Johnson Controls, Inc. 1Code No. LIT-4350300www.johnsoncontrols.com

OverviewValve OperationThe GM-7000 is an on/off valve with spring-loadedseat discs that are operated by a solenoids withprotected rectifiers to ensure quiet operation.When the valve is energized, the solenoid plunger ispulled into the coil, overcoming the force of the closeoffspring and the flow medium pressure. The valve seatdiscs are directly fixed to the plunger stem so the valvefully opens.The plunger is Teflon® coated, providing maintenancefreeoperation under permissible temperature andpressure specifications.Valve TypesThe GM-7000 valve is available with either single ortwin Class A or Class B solenoids and either 3/8 inchor 1/2 inch body thread connections.The GM-75_ _ models have Class B rated solenoidsand the GM-77_ _ models have Class A ratedsolenoids.Adjustment MethodsThe GM-7000 Series offers different types of flow orpressure regulator control. Models are available withmanual flow adjustment, direct-acting regulator, andlever-acting regulator control.No AdjustmentThe GM-7 _1_ model has a blank plate mounted ontothe bottom of the body casting for applications whereadjustment control is not needed or for applicationswhere separate adjustment control is already provided.Flow AdjustmentThe GM-7 _2_ model has manual flow control throughthe use of an adjustable screw. The screw adjusts theposition of an internal flow plug to determine the flowrate through the valve.Regulator AdjustmentThe regulator controls the gas pressure at the valveoutlet by positioning the regulator poppet for selectedthroughput flow and pressure. This is achieved by thevalve outlet pressure acting on the regulatordiaphragm, which balances against the presetregulator spring. Adjustment of the spring compressiondetermines the valve outlet pressure and thethroughput flow rate.The GM-7 _3_ model has a direct-acting pressureregulator. The direct-acting regulator operates bymeans of the regulator spring acting directly onto theregulator diaphragm. The direct-acting regulator isadjusted from the underside of the valve.The GM-7 _4_ model has a right-handed lever-actingpressure regulator. The lever-acting regulator operatesby means of the regulator spring acting onto a lever toposition the regulator diaphragm. The lever-actingpressure regulator is adjusted from the top of the valvewhen the valve is in the upright position (solenoid coilson top). Right-handed orientation is determined by theposition of the adjustment when looking into the inletconnection of the valve.The GM-7 _5_ model has a left-handed lever-actingpressure regulator. The lever-acting regulator operatesby means of the regulator spring acting onto a lever toposition the regulator diaphragm. The lever-actingregulator is adjusted from the top of the valve when thevalve is in the upright position (solenoid coils on top).Left-handed orientation is determined by the position ofthe adjustment when looking into the inlet connectionof the valve.2 GM-7000 Series Multi-function Gas Control Valve Product Bulletin

Range of RegulationPressure Regulator Models (GM-7 _3_,GM-7 _4_, and GM-7 _5_)The GM-7 _3_ model has an adjustable direct-actingpressure regulator and the GM-7 _4_ and GM-7 _5_models have an adjustable lever-acting pressureregulator. Both the direct-acting and lever-actingpressure regulators have the following pressure range:• Natural gas: 5 to 15 mbar (2 to 6 in. W.C.)• Liquid Petroleum (LP) gas: 22.5 to 30 mbar(9 to 12 in.
