Auxiliary air inlet air-assist closure
Cycle rate exceeds 400/minute
7013449 736HPA-NV Valve
Chromium-plated spool
Fluid body and air cylinder body are passivated 303
stainless steel with a chromium-plated spool. The
fluid inlet and outlet threads are 1/4 NPT female.
7028951 736HPA-NV Valve
Titanium nitride-coated spool
Fluid body and air cylinder body are passivated
303 stainless steel with a titanium nitride-coated
spool. The fluid inlet and outlet threads are 1/4
NPT female.
High pressure fluid inlet fittings are not supplied by
EFD. They are available from the pump supplier.
Specify inlet size 1/4 NPT.
The 736HPA stainless steel balanced spool valve applies uniform amounts of thick
materials like greases and silicones at pressures up to 172 bar (2500 psi).
To keep dots and lines consistent and prevent drooling between shots, the
736HPA-NV valve uses an adjustable stroke control to regulate opening surge and
closing snuff-back.

794 Series
Auger Valve
Auger valves use screw-feed technology with precision time and pressure controls to
dispense accurate, repeatable amounts of particle-lled materials, thermal interface
materials (TIM), or other highly abrasive pastes. The auger assembly can be easily
replaced to change the gap size as needed.
The robust tungsten carbide (TC) auger screw and uid body liner on the 794-TC
valve resists wear from highly abrasive pastes to ensure long valve life.

solder pastes. See Solder Products for details.

Radial Spinner Systems
Radial Spinner System
Features and Benets
Applies correct amount on every part
Applies material in correct location
Eliminates waste, mess, and rework
Operates in vertical or horizontal
position
The Radial Spinner System applies consistent amounts of adhesives, lubricants,
and other production uids inside cylindrical parts between 10.2 mm (0.4") and
127.0 mm (5.0") in diameter.
The system combines a compact air-driven motor with a low maintenance EFD
dispense valve and ValveMate controller. The valve dispenses a precisely metered
amount of uid onto a spinning disk attached to the motor. As uid reaches the
edge of the disk, it spins off, forming a neat band inside the part.
