Dispensing Valves

Diaphragm Valves
This manual, hand-held dispenser requires no valve controller. It is ideal for dispensing cyanoacrylates and other low-to-medium viscosity materials.
Viscosity Range: 1-5,000 cPs or 1-25,000 cPs thixotropic fluids

In this design, fluids do not contact the actuating components within the dispensing valve, making it ideal for dispensing reactive materials such as cyanoacrylates and solvent-based products.
Viscosity Range: low to medium
Disposable Fluid Path Valves
The Model 455 dispensing valve is a pneumatically operated, normally closed pinch valve with a disposable fluid path. It was designed to dispense materials with extreme precision. The valve’s micrometer control feature allows users to precisely adjust the material flow, ensuring that materials are dispensed consistently and accurately.
Viscosity Range: low to high

The Model 455 Micro-Spray Valve is a pneumatic pinch valve outfitted with a stainless steel spray nozzle and spray regulator assembly. The spray nozzle is an external air-mix type which utilizes a standard luer-lock design allowing different gauge tips to be exchanged to adjust flow rate needs.
Viscosity Range: low (<5,000 cP)

The Model 826 is a pneumatically operated, normally closed pinch valve. This dispense valve dispenses a wide variety of materials, and is specifically designed to dispense thicker, stringy materials with ease. The valve is highly precise and obtains its precision from lockable controls that facilitate the adjustment of three critical parameters: the flow rate through the valve, the amount of tube closure, and suck-back.
Viscosity Range: low to high, including stringy materials

The Model 828 normally open disposable fluid path valve is designed to provide larger flow rates while still maintaining precise control over material flow rate. This dual-piston pinch valve can be used with many materials and features a suck-back control so it can handle stringy and tacky materials with no mess.
Viscosity Range: low to high, including stringy materials

The Model 830 normally closed disposable fluid path valve is designed to provide larger flow rates while still maintaining precise control. This dual-piston pinch valve can be used with many materials and features a suck-back control to handle stringy and tacky materials with no mess.
Viscosity Range: low to high, including stringy materials
Needle Valves
This automatic, hand-held needle valve is designed to deliver precise dots or very fine beads of low- to medium-viscosity fluids. The valve's design is compact and lightweight, making it easy and comfortable to handle.
Viscosity Range: low to medium

This pneumatic, normally closed needle valve is designed to deliver precise dots or very fine beads of low- to high-viscosity fluids. The valve's stroke adjustment allows for fine-tuning of the dispense volume, ensuring precise and consistent deposits. Air pressure through the valve retracts the needle assembly from the seat allowing fluid to flow from the valve fluid inlet to the dispensing tip.
Viscosity Range: low to high
Spool Valves
The Model 775 is a pneumatically operated spool valve that is designed to accurately dispense a variety of fluids. The valve's accuracy comes from two main features, its suck-back control and adjustable flow control. The suck-back feature greatly increases accuracy and repeatability when dispensing materials. Having control over the amount of suck-back assures consistent, stringless dispensing of tackier materials, and prevents droplets from remaining on the dispense nozzle when using lower viscosity materials.
Viscosity Range: Medium to high, including stringy materials
Spray Valves   (for use with spray gun systems)
Model 110 Standard-Flow Spray Valve
Dymax spray valves provide users with manual control over the valve and its spray and are ideal for the following applications: masking of turbines or other metal surfaces before surface treatment; masking medical implants before finishing treatments; conformal coating of circuit boards; spraying solvents for cleaning part surfaces; coating large parts with grease or other lubrication before assembly.
Viscosity Range: <10,000 cP

Model 210 High-Flow Spray Valve
Dymax spray valves provide users with manual control over the valve and its spray and are ideal for the following applications: masking of turbines or other metal surfaces before surface treatment; masking medical implants before finishing treatments; conformal coating of circuit boards; spraying solvents for cleaning part surfaces; coating large parts with grease or other lubrication before assembly.
Viscosity Range: >10,000 cP
