DISPENSINGHand Held ValvesHand Held Valves<strong>Loctite</strong>® brand hand held dispensing valves are used where ergonomic design forhand dispensing of fluids is desired. Designed for use with <strong>Loctite</strong>® brand controllersand reservoirs, these hand held valves utilize passive wetted components for universalcompatibility with many fluids. Selection of a <strong>Loctite</strong>® brand hand held valve is basedon the desired dispensing controls, the dispense principal of the delivery system, andother process requirements.PRODUCTItemNumberTypeViscosityRangeDispensePatternsUsed to DispenseStrokeAdjustmentActuationLOW VISCOSITY CYANOACRYLATE APPLICATOR<strong>Loctite</strong> ®LV Hand HeldApplicator97130 Pneumatic LowDrop,Dot, BeadInstant Adhesives,RetainingCompounds,ThreadlockersYesFootGENERAL PURPOSE APPLICATORS<strong>Loctite</strong> ®ManualHand HeldApplicator97111 ManualLow toMediumDrop,Dot, BeadInstant Adhesives,Light Cure/Acrylics,RetainingCompounds,ThreadlockersYesFinger<strong>Loctite</strong> ®PneumaticHand HeldApplicator97112 PneumaticLow toMediumDrop,Dot, BeadInstant Adhesives,Light Cure/Acrylics,RetainingCompounds,ThreadlockersYesFoot<strong>Loctite</strong> ®PneumaticHand HeldApplicator97116 PneumaticLow toMediumDrop,Dot, BeadInstant Adhesives,Light Cure/Acrylics,RetainingCompounds,ThreadlockersYesFingerPINCH TUBE APPLICATORS<strong>Loctite</strong> ®Vari-Drop Applicator9713197132Pinch TubeLow toMediumDrop,Dot, BeadInstant Adhesives,RetainingCompounds,ThreadlockersYesFinger58
Dispenser, Controller and Reservoir arerequired with these valves.DISPENSING Hand Held ValvesLOW VISCOSITY CYANOACRYLATE APPLICATORLOCTITE ® LV HAND HELD APPLICATORItem Number: 97130The <strong>Loctite</strong>® LV Hand Held Applicator is a pneumatically operated, adjustableseat valve designed for accurate dispensing of low viscosity adhesives includingcyanoacrylates. The valve body and stem are constructed of PTFE to preventpremature curing and together with the fine tuning strokeadjustment, this valve can deliver very small and repeatabledrop sizes shot after shot. This valve must be used inconjunction with a <strong>Loctite</strong>® brand controller and productTypereservoir, sold separately.Viscosity RangeFeatures:• Dispenses low viscosity cyanoacrylates, anaerobic,and other adhesives under 10,000 cP• Slim, ergonomic design greatly reduces hand fatigue• Forward closing to avoid air entrapment and potentialpremature curing of cyanoacrylates• Stroke adjustment for fine -tuningof dispense characteristics• Dispenses repeatable drop sizes down to 0.005 g• Easy repair/replacement of wetted componentsTheory of OperationWhen used in conjunction with a pressure-time controller andadhesive reservoir, the valve is opened by an internal, single -acting cylinder and piston rod. After initiating the control cycle,the piston is pulled, opening the PTFE flow channel, andallowing adhesive to pass. At the end of the controlled open time,pressure is released and the valve is closed via an internal springmechanism, closing off the flow channel. The amount ofdispensed adhesive is controlled by adjustment of air pressure,valve open time, size of dispensing needle, and piston stroke.NO FLOWFLOWThe RED represents the fluid path.TECHNICAL SPECIFICATIONSPneumaticLowSize7" L x 1.6" Maximum Diameter(170 mm L x 40 mm Maximum Diameter)Weight 5 oz.
