EFD 736HPA INSTALLATION GUIDE

Introduction

The 736HPA is a normally closed, air-actuated, balanced
spool-type valve designed to operate at fluid pressures
up to 2,500 psi (172 bar). Ideal for consistent dispensing
of industrial sealants and greases, the 736HPA valve is
simple to use and will operate many millions of cycles
without wear or leakage.

Installation

1. Mount valve with an EFD universal

valve mount (#7002VM) or other
fixture.

2. Thread the fluid inlet fitting into

the fluid inlet hole.

Note: The fluid inlet fitting and hose
must be obtained from the high
pressure pump supplier. Ensure that
the hose and fitting are rated for the
maximum operating pressure of the
pump system.

3. Connect the fluid feed hose to

the fitting.

4. Connect valve control air hose to

the ValveMate

™

controller (or other
pneumatic switch) used to control
valve open-time.*

5. Install appropriate threaded nozzle

to the valve output or use a
dispensing tip adapter (#2186) with
EFD SafetyLok

™

dispensing tips.

6. Check to be sure all fluid and air

connections are tight.

7. Make sure valve operating

pressure is set at 70 psi (4.8 bar).

8. Be sure delivery pump pressure

does not exceed 2,500 psi
(172 bar).

9. Place a cup under the dispensing

tip or nozzle and actuate the
valve until fluid flows steady.

10. Set desired flow rate by adjusting

fluid pressure or changing the
outlet tip size.

11. Set desired deposit size by

adjusting valve open-time. Refer
to valve controller operating
manual.

Prior to installing this valve, please
read the associated reservoir and
valve controller operating instructions
to become familiar with the operation
of all components of the dispensing
system.

How the Valve Operates

open closed

➃➃

➂➂

➁➁

➀➀

When air pressure at 70 psi (4.8 bar) is applied, the piston shifts the
spool

➀➀

to the open position, allowing fluid to flow. At the end of the

cycle, spring force on the piston

➁➁

shifts the spool to the closed
position, stopping fluid flow. During the closing action, the 736HPA
provides snuff-back of fluid for clean cutoff.

The stroke adjustment

➂➂

can be used to regulate snuff-back to an
amount appropriate for the fluid being dispensed. Stroke adjustment
can also be used to reduce fluid surge when the valve opens to ensure
consistent bead widths and dot profiles. The stroke is adjusted by
moving the stroke limit stop:

1. To access the stop, first remove the air input hose from the push-in
air coupling by pushing down on the release ring while pulling up
on the tubing.

2. Insert the 1/8” Allen wrench through the air coupling and engage
the stroke limit stop.

3. Adjust the stop toward or away from the piston to vary the stroke.
To decrease the amount of opening surge and closing snuff-back,
extend the limit stop by turning the wrench clockwise. To increase
the amount of surge and snuff-back, retract the limit stop by
turning the wrench counterclockwise.

Note: Adjusting the stroke does not affect the flow rate.

4. Install the air input hose by pushing the hose into the coupling.

Note: For striping applications, fluid surge can be reduced further by
lowering the valve operating air pressure down to, but not below,
40 psi (2.7 bar).

When dispensing very thick fluids at high cycle rates, the double-acting
feature ensures rapid closure. A double-actuating air input

➃➃

is provided
on the side of the air cylinder to allow double-acting operation using air
pressure to both open and close the valve.

The amount of fluid dispensed is determined by valve open-time, fluid
pressure, dispensing tip size and fluid viscosity.

ValveMate Concept

The ValveMate 7000 provides easy adjustment of valve
open-time for maximum end-user convenience and
efficiency. Valve open-time is the primary control of deposit
size. The 7000 puts push-button adjustment of valve
open-time where it needs to be – at the valve location.

Deposit size can be programmed by pressing the
PROGRAM button in the SETUP mode. This affords an
easy starting point for selecting deposit size.

Note: The EFD Ultra®TT 325 and 525 XYZ automated
dispensing systems have integrated ValveMate controllers
for operating all EFD dispense valves.

For consistent dispense valve operation and easy adjustment
of valve output, EFD recommends using the ValveMate 7000
controller on all automatic, semi-automatic and benchtop
applications.

The EFD Ultra TT Series positioning systems incorporate
dispensing control into the main system.
