Precision needle valve 741V-AL for low viscosity fluids, aluminium - Nordson EFD 7021235

With low viscosity fluids the dead volume between valve seat and needle outlet decides how repeatable the shot is. On the 741V-AL the stainless steel valve needle seals directly in the dispensing needle inlet, so practically no residual volume is left inside the valve.

Benefits in use

• The stainless steel valve needle seals directly in the dispensing needle inlet, leaving virtually no dead volume in the valve.
• Designed for many millions of cycles without maintenance, which cuts machine downtime.
• Clean and repeatable delivery of low viscosity fluids, also at short cycle times.
• Air cylinder and fluid body in hard coated anodised aluminium, resistant to cleaning agents and abrasion.
• Overall length 114.6 mm, so the valve fits into tight installations on assembly machines and dispensing robots.
• Simple to operate without special tools, which keeps the machine manageable for the operator.

Applications

Automated dispensing of low viscosity adhesives, oils, solvents, primers and cleaners, assembly machines and dispensing robots in electronics, medical device and precision manufacturing.

Compatibility

The valve outlet takes dispensing needles, the needle size sets the deposit cross section. The valve is driven by a valve controller, which is not included.

Standards and compliance

The property table does not list the valve as ESD safe.
