1.3 For Your Safety
WARNING!
If chemical products are not properly handled, damage to health can result!
Observe general safety regulations for the handling of chemicals!
Observe the manufacturer’s instructions as stated in the Material Safety Data Sheet
(MSDS)!
Always wear safety glasses when operating with pressurized air!
Use only original substitute and spare parts.

1 Please Observe the Following
1.4 Field of Application (Intended Usage)
The Diaphragm Valves 97135/97136 are suitable for the exact application of LOCTITE
®
products. They show no suck back.
The Diaphragm Valve 97135 is equipped with an internal product bore of ∅2 mm. It is
used for anaerobic products up to a viscosity of 2,500 mPas.
The Diaphragm Valve 97136 is equipped with a internal product bore of ∅3 mm. It is
used for anaerobic thixotropic products up to a viscosity of 5,000 mPas.
For each product and corresponding application of the dispense valves, various
dispensing needle types and sizes are available:
–Conical dispensing needles of polyethylene for viscous products and large dispensed
quantities.
–Stainless steel needles for thin fluids and UV curing products.
–Flexible dispensing needles of polyethylene.
For high flow rates the diaphragm valve can be upgraded from feedline 1/4” to 3/8” by
the feedline upgrade kit, type no. 97220.
The diaphragm valve is used as a stationary applicator unit. It is mounted directly at the
dispensing position. The free end of the product feedline is connected to the product
reservoir.
As product reservoirs, 0.5 l and 2 l tanks are available.
A control unit of the LOCTITE
®
equipment line provides the control of the diaphragm
valve.

8
2 Description
2.1 Theory of Operation
The LOCTITE
®
product is transported through a product feedline to the diaphragm valve
by the dispensing pressure in the product reservoir.
At the shut off valve assembly PTFE material is used for the area in contact with the
adhesive to prevent curing of adhesive in this part of the diaphragm valve.
The opening of the diaphragm valve takes place by pressuring an internal single acting
cylinder. In the inactive position, the diaphragm valve is closed by spring force. A piston
pushing against a diaphragm, which seals off the product bore in the valve, achieves
sealing in idle position.
The floating mounted diaphragm enables easy repair and service.
As a result the diaphragm valve is not suitable for moisture sensitive product like CA`s.
The amount of product dispensed is controlled by:
–The amount of pressure in the reservoir.
–The length of time the shut off valve remains open.
–The dispensing needle.
The more precise and constant the amount of Loctite
®
product the longer has to be the
dispensing time and
lower the dispensing pressure.

4 Installation
– Keep the pressure hose as short as possible. Short switch-on and switch-off times for
the diaphragm valve are within reach.
– Keep product feedlines as short as possible. The shorter the feedline the smaller the
specific resistance and the lower the dispensing pressure can be.
– Avoid kinking of feedlines and pressure hoses.
– Typically, the pressure hose and product feedline should not be longer than 2 m.
– Do not use inflexible hoses and feedlines, so that unnecessary loads on the fittings will
be avoided.
– Keep all fittings tight.
–
No direct sunlight; no UV light!

5 Dispensing
5.1 Priming the Diaphragm Valve
•Before initial operation:
Hand-tighten the valve actuator and
valve body by means of two combination
wrenches (wrench size 17 mm) in
accordance with the data of the sticker
(max.17 Nm). Only then it is guaranteed
that the valve is tight.
Note!
To avoid air bubbles during dispensing, the product feedline and the diaphragm valve
must be filled.
CAUTION!
Place a container under the diaphragm valve since the product will flow out!
•Perform the filling of the product feedline acc. to the operating manual of the used
Controller.
5.2 Adjusting the Dispensed Quantity
Note!
Adjust the dispensing quantity according to Chapter 5 of the operating manual of the
used controller.
5.3 Shutdown
To protect anaerobic products from curing, remove dispensing needle leaving Luer-Lock
adapter
6
exposed to air.
Shutdown for longer Periods.
•Remove product out of the reservoir.
•Purge the diaphragm valve with air until no product run out.
5.4 Returning to Operation
•Insert product bottle into the reservoir.
•Purge the diaphragm valve with air until product run out.
•Check the dispensing quantity acc. to Chapter 5 of the operating manual of the used
controller.
ACHTUNG:

5.5 Upgrading the Feedline/Fitting
Note!
For viscous products, a feed tube adapter with a 9.5 mm product feedline, type no.
97220, is available by ordering part no. 135561.
•Disconnect the feedline and unscrew the
fitting.
•Screw the new fitting into the shut off
valve 4.

6 Care, Cleaning and Maintenance
6.1 Cleaning
The diaphragm valves have to be cleaned if
- idle periods of the dispensing system exceed seven days, and/or
- a different type of product is to be dispensed and/or
-
valves are disassembled for replacement of spare parts.
Liquid residues may be removed with several solvent. Chlorinated hydrocarbons will
obtain optimum results; acetone would be the best alternative among nonCHC solvents.
WARNING!
If chemical products are not properly handled, damage to health can result.
Observe general safety regulations for the handling of chemicals!
If diaphragm valve is cleaned after prolonged idle periods or for a switch to a different
product, be sure to place new Loctite
®
product bottle into the tank, see operating manual
of the used reservoir.
Priming of the feedline, see operating manual of the used controller.
Setting of dispensing parameters, see operating manual of the used controller.
6.2 Maintenance
To ensure trouble-free operation of the diaphragm valves 97135/97136 we recommend
servicing at regular intervals.
•Every 6 months
Replace diaphragm

7 Troubleshooting
Type of malfunction Possible causes Correction
No product or too little
product.
– Product feedline and/or pneumatic
hose not connected correctly or
kinked.
•Connect the product feedline correctly.
If kinked, replace it.
– Control pressure not adequate.
Control pressure must be between
5 and 7 bar.
•Check and adjust the control pressure.
– Curing in the product feedline or in
the dispensing needle.
– Curing in the diaphragm valve.
•Replace the product feedline and/or the
dispensing needle.
•Replace the shutoff valve 4and the
diaphragm 3.
– Controller incorrectly adjusted. •Check the controller setting (see
operating manual for the controller).
– Product reservoir not switched on,
depressurized or pressure is too
low.
•Check the reservoir (see operating
manual for the product reservoir).
Diaphragm valve does
not open.
– Actuator 2of the valve is
contaminated with product.
•Replace the actuator 2and the
diaphragm 3.
Dispensing operation is
irregular.
– Actuator 2and shut off valve 4are
tightened too much.
•Back off actuator from shut off valve,
proceeding in small steps,
90° max (1/4 turn).
Dispensing sequence
too short despite long
time setting.
– Disassemble valve and push button
on controller to actuate the actuator:
> air escapes at the plunger.
•Replace the actuator 2and the
diaphragm 3.
