safety
The safety of individuals and equipment in the
workplace is one of the main responsibilities of
company managers, shop floor supervisors,
prevention organizations and standards bodies.
Several Legris ranges have been specifically designed
to meet the operating requirements and safety
standards that apply to all industrial organizations.

Some examples are highlighted below.

lock-out valves
Designed to offer maximum flow capacity, Legris lock-out
valves lock the piston by simultaneously cutting off the
supply and exhaust air.
Found on page B21.

pneumatic slow start valves

These valves allow start-up air pressure to increase
gradually and thus prevent shocks within the system, saving
wear and preventing injury to users and components.
Found on page B33.

C9000 automatic quick disconnect safety couplers

Even if disconnection is performed rapidly, the safety of
the end-user is guaranteed due to a very short vent-time
and two stage release of body and plug.
Found in section K.

lockable ball valves

These ball valves have been developed in order to prevent
potentially dangerous consequences caused by unintended
operation, thus meeting international safety requirements.
Found on pages R10 & R11.

dynamic safety blowguns

An integrated pressure regulator ensures pressure
reduction and safety to the user and machinery at all times.

medical industry applications
Legris, inventor of push-to-connect fitting
technology, offers a wide variety of products
suitable for medical activities, such as cartridges,
fittings and tubing. Materials and grease can
be adapted to meet various medical applications
like dental, anesthesia and dialysis equipment.

Here are some solutions specifically adapted

to medical applications:

carstick
The concept which combines LF3000® one-piece cartridge
with a specially designed protection and dispensing sleeve.
Materials: nylon button and protection sleeve, nickel-plated
brass retaining sleeve, nitrile seals. Found on page A47.

LF3800 push-to-connect fittings

Offers excellent resistance to aggressive environments and
fluids. Materials: stainless steel AISI 316L and FKM seals.
Found in section E.

LF3000 push-to-connect fittings

Designed using a simple and widely proven operating
principle which allows instant connection and disconnection.
Materials: nylon bodies, nickel-plated
brass bases, nitrile seals. Found in section A.

LF3600 push-to-connect fittings

Can be used in aggressive environments due to its chemical
nickel-plating. Materials: chemical nickel-plated brass and
FKM seals. Found in section D.

tubing
FEP 140 tubing provides excellent resistance to aggressive
and corrosive agents and to high temperatures. Nylon tubing
provides optimum mechanical properties and has good
chemical resistance. Polyurethane tubing has high flexibility
which allows for compact cabling where a small bend radius
is required. Found in section M.

recommendations
packaging industry applications
With a wide variety of ranges, the Legris offer suits many
industrial activities. One of them is packaging applications
like case palletizing, labeling, filling, conveying and
rinsing/pasteurizing.

Here are some products suited for the packaging industry:

knobless flow controls

Features push-to-connect connection, compact size,
orientable, recessed screw, and fine threads. The recessed
adjustment screw reduces external dimensions allowing use
in reduced spaces. It also provides security and helps to
prevent unwanted adjustment.
Found on pages B10 & B11.

pressure regulators
Used to stabilize the pressure at a given value that is applied
to pneumatic equipment, whatever the fluctuations of
pressure upstream. The pressure outlet is fully controlled by
an adjustment screw which is calibrated to show pressure
setting levels. Found on page B37.

miniature flow controls

Control the speed of small bore cylinders. Control is achieved
gradually due to the extreme sensitivity of the adjustment
screw, which allows exceptionally fine setting levels. Found
on pages B12 & B13.

metal flow controls

Suitable for use in severe conditions. Designed to withstand
high temperatures, sparks, abrasion, etc. Locking nut
guarantees adjustment stability against vibration and
prevents unwanted adjustment. Found on page B19.

slide valves
Effect an immediate isolation of the air line by venting the
system to atmosphere. They are compact, neat, aesthetic and
can be directly installed in the circuit. Found on page B29.

manually operated 3-way venting valves

Guarantee immediate isolation of the air line by venting the
system to atmosphere. Easy to operate, it can be used
whenever the system has to be frequently vented.
Completely orientable, a number of valves can be mounted
side by side, even in reduced spaces. Found on page B39.
