SPV2000 Spool Valve
TechnoDigm™ SPV200 is a pneumatic valve that has been designed specifically to address dripping and tailing issues effectively. The internal design creates a suck-back effect as opposed to standard piston valves. The suck-back feature greatly increases accuracy and repeatability when dispensing materials. This feature prevents droplets from remaining on the dispensing tip when using lower viscosity fluids. This feature also enables the user to control the amount of suck-back via an adjustment knob on top of the valve. It is an effective valve for dispensing medium to high viscosity epoxies and adhesives such as RTV, grease, gasketing epoxies, and high viscosity sealant. The stainless steel body allows the valve to be used for any kind of material even those corrosive types.
Features :
- Adjustable suck-back control
- Easy to clean and maintain
- Able to use various types and sizes of dispensing needles
- Compatibility with most standard fluid packages and delivery systems
- Stainless steel wet body
Snuff Back Valve
The Snuff Back valve is designed to dispense medium to high viscosity material. The working principal of this valve is that the retraction of the piston generates “Negative Pressure” that allows the “Pull Back” of material to achieve a quick cut off and prevents dripping of material.
The Snuff Back Valve is suitable for dispensing applications such as gasketing that requires a clean cut-off and faster shut-off control. This valve is also suitable for large volume dispensing of highly viscous material in dispensing applications such as potting, filling or encapsulation. The unique balance spool design allows the valve to operate with very high material pressure conditions without any problem.
Features :
- Compact size and weight
- Easy to maintain and operate
- Adjustable snuff-back cutoff
- Suitable for wide range of material
- Stainless steel wetted body
Needle Valve
TechnoDigm™ Needle Valves are designed for use in a variety of industries and applications. They are the ideal dispensing component when the most accurate, repeatable and consistent amount of liquid is required, such as in applications that require low viscosity liquids. It can be easily integrated into high volume production automation systems for the manufacture of semiconductor, medical device, optoelectronic, automotive parts.
Features :
- Positive shutoff
- Zero dead fluid volume
- Designed to be low maintenance
- Wide range of dispensing volumes
Temperature Controlled Valve NV500H
By maintaining a constant fluid temperature during dispensing, the NV500H valve system will prevent inconsistent dispensing volume caused by temperature fluctuations. In addition, it can also be used to improve dispensability of high viscosity materials.
A simple dedicated temperature controller allows for simultaneous setting of temperatures of up to 125 degrees °C for both the dispensing valve and the 30cc syringe.
Applications
- Precise hot melt dispensing
- Effective dispensing of heated applications like Underfill encapsulation, COB encapsulation, Dam and Fill, and more
- Maintaining a lower uniform fluid viscosity to reduce cycle time by keeping fluids in the syringe and valves above room temperature/elevated temperature
Features :
- Integrates easily with automated dispensing systems
- Control temperature up to 125 degree °C
- Fast heating speeds
VC1000 Valve Controller
VC1000 is a universal dispensing valve controller that features an easy-to-use touchscreen interface for setup and operation. It's made to operate a variety of pneumatic dispensing valves as well as direct syringe control. Users will be able to adjust accurate pressure for dispensing applications with the help of digital pressure displays. Precision dispensing applications benefit from high resolution and precision dispensing control systems. It can be used with other dispensing valves that require a high response control signal because it has an external solenoid valve control signal built-in.
