Tube Squeezing Valve

Properties of Tube Squeezing Valves

• Adhesive only contacts the flexible tube
• Minimal wear of valve components
• Easy cleaning through tube replacement
• Gentle dispensing of shear-sensitive materials
• No dead volumes in dispensing path
• Precise volume control through squeeze degree

Operating Principle

• Pneumatic or mechanical squeezing mechanism
• Exact dispensing through stroke and time control
• Reproducible dispensing results like other dispensing valves
• Fast switching times for high cycle rates
• Retraction function to prevent stringing

Applications

• Medical Technology: Sterile dispensing of biocompatible adhesives
• Conductive Adhesives: Gentle dispensing of particle-containing systems
• Moisture Curing Adhesives: Dispensing of reactive systems
• Food technology: Contamination-free dispensing

Material Compatibility

• High-viscosity adhesives: Dispensing of thick pastes and masses
• Sustainable Adhesives: Gentle processing of sensitive formulations
• Abrasive materials: Protection of valve components
• Aggressive media: Chemically resistant tube materials

Advantages Over Other Valve Types

• No product contact with metal parts
• Less cleaning effort during product changes
• Extended shelf life of adhesives through closed system
• Lower operating costs through reduced wear
• Easy validation for medical and pharmaceutical sectors

Process Parameters

• Tube inner diameter: 1 to 10 mm
• Dispensing volume: 0.01 to 10 ml per dispensing
• Controlled pot life for reactive systems
• Defined flash-off time after dispensing
