741V Needle Valves
The 741V Series needle valve design applies low viscosity assembly fluids with accurate, extremely close repeat deposit control.
Overview
During operation, controlled pulsed air acts on the piston to withdraw the needle a preset distance from the needle seat to provide exact, repeatable fluid flow. The stainless steel needle seats in the tip adapter, virtually eliminating dead fluid volume between shots.
The Nordson EFD needle valve features adjustable fluid flow control.
Available Models
741V Series
Actuated by an external solenoid and operates at more than 400 cycles per minute at pressures up to 300 psi (20.7 bar).
741V with BackPack™ Valve Actuator
Actuated by a compact solenoid installed on the valve’s actuating air cylinder, creating a faster response time and less variation in shot size due to plant air supply or air line length fluctuation. Achieves air actuation speeds as short as 5 to 6 milliseconds and cycle rates up to 800 cycles per minute.
Valve Systems & Controllers
Engineered for the most demanding manufacturing environments
Nordson EFD valve systems are proven to provide precise, reliable fluid dispensing control for tens of millions of trouble-free cycles before maintenance is required.
The Complete Valve System
The complete system includes the 741V dispense valve, ValveMate™ 8000 controller, fluid reservoir, and dispense tip. For even faster throughput, integrate with an EFD automated dispensing system.
