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.

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.

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.

Technical Data

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!
