Corrosion-Proof Six mm PTFE Needle Valves
Aalborg® has announced the release of its VT6 6mm PTFE Needle Valves. Simplicity of
design (only 6 components) assures minimal sources of leakage, quick disassembly, and
easy maintenance.
Ideal for relatively high flow ranges while maintaining linear, repeatable flow rate
performance, the VT6 can be used in pressure, non-critical vacuum service, or as shut-off
valves. The unique radially compressed PTFE o-ring feature allows quick compression
adjustments without disassembly.
PTFE and PCTFE materials make the VT6 Valves reliable choices for laboratory and
industrial applications requiring corrosive gas and liquid regulation or high-purity service.
Design Features Include:
- Rigid PCTFE valve spindles virtually eliminate "creeping."
- Panel Mountable.
- 3/8" FNPT ports.
- Fluids contact only PTFE/PCTFE materials.

|
|
General-purpose valve for use with a wide variety of medium to high-viscosity fluids. A slight snuffback at the end of the dispensing cycle prevents dripping between shots.
For use with:

Handheld dispense valves are a good choice for manual assembly applications where a timed shot is not required and a relatively large amount of fluid is being consumed.
Operation is simple and straightforward. Fluid is supplied to the valve from a pressurized 1 liter or 5 liter tank. To apply fluid, the operator places the dispense tip in position and presses a lever on the side of the valve. Releasing the lever stops the flow with a fast clean cutoff.

The VC-1195A is a 4-way dispensing valve controller that can be used to control one or two dispensing valves with dual air ports for 4 way pneumatic operation simultaneously. The secondary air input will close a valve faster than using the valve's internal return spring, providing an increase in speed and suck-back.
Features
• Improves a valve's operational speed and suck-back
• Increases shot size accuracy
• Simultaneous control of two valves
• Timing interval from 0.01 to 31 seconds
• Fast response internal pneumatic solenoid

The HME-500 are particularly suitable for high production speeds with simultaneous high demands on accuracy and cleanliness. They combine the Baumer hhs competence from electromagnetically operated cold glue technology with the special features of hot-melt application.The HME guns are extremely quick switching, free from wear and tear and maintenance friendly. Their compact design without compressed air connection and solenoid gun allows the installation even in the smallest gaps. The use of high quality materials and ideal heat distribution not only guarantee long life but also optimum quality of the glue application.

Measuring valves are the essence of dualine lubrication systems. They are munted close to the lubrication points and hydraulically operated by pressure from the first and then the second of the two supply lines. On each pressurisation cycles, they indirectly discharge fixed volume of lubricant to the bearing etc.
|
|
Two ranges of line mounting adjustable metering units for use with a dualine system, which discharge a fixed volume of lubricant to half the lubrication points on pressurisation of one line and to the remaining points on pressurisation of the second line.
Benefits:
* Each measuring valve can have from one to four independent operating sections.
* Two normal discharge connections for each operating section reduce the overall cost of the system.
* Any section of the valve can be modified to one discharge, allowing a double sized discharge or an odd number of outlets on the valve.
* Wide stepless adjustment bands for each size of valve allow optimum lubrication delivery to every bearing.
* Positive hydraulic operation with visible indicator of operation.

Parker’s RB9 Multi-Function Flare Valves are used as service valves in mini-split heat pumps. The valves isolate sections of a system for servicing and provide a means for charging refrigerant into a unit. The valve also holds a restrictor and screen to meter refrigerant and filter debris, increasing system efficiency.
* Inclusion of a restrictor into the valve provides precise refrigerant metering to increase efficiency.
* Noise and vibration through the unit are reduced by inclusion of the restrictor into the valve.
* Inclusion of a screen into the valve filters dirt and debris prior to entering the restrictor, maintaining full flow and enhancing performance.
* Captivated stem-design holds the stem within the valve to prevent it from releasing when the cap is removed or the unit is serviced, reducing the potential for injury.
* Combined functionality of valve, restrictor, and screen reduces component inventory (shut-off valve, field-access gage port, expansion device, filter screen or strainer, line-set connector, check valve, by-pass circuit, & capillary tubes) leading to a reduction in overall installed cost.
* Combined functionality of valve, restrictor, and screen also reduces space requirements within a unit and eliminates braze joints to reduce potential leaks paths.
