Product DescriptionProduct DescriptionScrew Dispensing Valve:Introducing the Screw Dispensing Valve, an exceptional screw valve metering dispensing head crafted for precision! Primarily utilized for metering hot melt adhesives and thermal conductive adhesives with medium to high viscosity, this valve offers unparalleled flexibility in adjusting glue volume and coating diverse workpieces. Its core components, the rotor and stator, ingeniously create a fully sealed metering chamber, ensuring continuous metering dispensing unaffected by fluid viscosity. Choose from optional high-flow screw dispensing valves, micro screw dispensing valves, and dual-liquid screw dispensing valves for a tailored solution.Experience the revolutionary screw dispenser, which elegantly utilizes screw rotation for precise suction and dispensing, finely scripting dots and lines. This volumetric metering screw pump operates seamlessly, unimpeded by liquid viscosity. Through its innovative endless piston mechanism, continuous dispensing is effortlessly achieved.Dispensing Needle:Innovatively designed to cater to diverse requirements, these dispensing needles are perfect for both single component adhesives and dual component glues (AB adhesive).SpecificationTechnique parameter for screw dispensing valve:ModelD03D15D45D60D70Measurementslength 228 mm, ? 33 mmlength 274 mm, ? 40 mmWeight340g650gOperating pressure0-6 barMax. dispensing pressure20 bar21 bar20 barViscositywatery to pastyDosing volumeca. 0,003 ml/revca. 0,01 ml/revca. 0,05 ml/revca. 0,14 ml/revca. 0,53 ml/revVolume flow0.03-0.36 ml/min0.5~6 μL/s0.1-1.2 ml/min1.6~20 μL/s0.5-6.0 ml/min8.3~100 μL/s1.4-16.0 ml/min23.3~266 μL/s5.3-16.0 ml/min88.3~1000 μL/sMin. dispensing quantity0.00025 ml0.0008 ml0.004 ml0.015 ml0.06 mlDispesning accuracy± 1 %Stator materialhi-techi-act / hi-per / hi-techi-perMaterial inletG 1/8" DIN/ISO 228G 1/8" DIN/ISO 228Material outletLuer-Lock (patented)Wetted partsAL / stainless steel / hi-tec/ UPEAL / stainless steel / hi-per/ UPE (optional act/tec)AL/ stainless steel / hi-per / HD-PEOperating conditions10 - 40 °CMax. speed125rpm*Company ProfileFAQQ1: What products does your company have?A: HOLS is a leader in intelligent manufacturing, with a business focus on three main areas: customized production lines, standard products, and comprehensive testing services.
