A1 INSERTS INTRODUCTION

INSERTS

The first section of the Handbook contains products intended for installation into metals (Section
Two products are to be installed into plastic). The inserts are designed using the insert prin-
ciple, which uses a pin to expand a grooved section of the insert's body into the housing wall
to effect a seal and retain the component. The pin, which has been pre-installed, is driven
into the body. Using friction and penetration, the lands bite into the housing material. The Lee
Company does not recommend the use of coatings or surface treatments in the area of the
installation hole where the Lee component is to be installed. Do not clean the insert prior to
installation. The assembly is prelubricated for proper installation.

Installation
Force

Kg F

The insert principle eliminates the need for threads and o-rings. Simply insert the component
into a drilled hole and drive the expander pin flush to within 0.25mm (0.010") above flush of
the insert. The installation tool can bottom on the insert body. Lee Installation Tools are avail-
able for each product and part numbers are listed on each page.

Since inserts can only be installed in one direction, most come in forward and reverse flow
versions to provide design flexibility.

A3 INSERT CHECK VALVES

The IMH Chek™ is a threadless, cartridge-style
insert designed for simple, low cost installation
into manifolds, and is based on the same hard
seat Lee Chek® designs used in flight control
systems of almost every aircraft flying today.

A robust design and 100% testing
ensures consistent, long-
term performance up
to 28 MPa (4060
psid) and 149°C
(300°F) or higher
depending on
specific applica-
tion requirements.

A high quality metal to metal seat limits leakage in the checked direction to no more than 20
sccm of air at 172 kPa (25 psi) differential. The valves are compatible with hydraulic fluids,
brake fluids, fuels and oils. Integral safety screen protection is available, (see drawings below).

Integral Screened Forward

Screened Reverse

IMH Cheks come in two styles, “axial” and 832 models are side exit flowing. Some
“side exit”, (see drawings below). 558, 855 models are available with a ceramic ball as
and 400 Bar models are axial flowing and the standard.

IMH Relief Valves are designed to protect
systems from over pressurization or to
attenuate pressure spikes. These valves
are not suited for upstream pressure
regulation.

As with the IMH Chek, the relief valve is
a threadless, cartridge style insert de-
signed for simple, low cost installation into
manifolds, in the most compact package
available anywhere.

A high quality, metal-to-metal seat provides long life and extremely low leakage, as well as
compatibility with a wide range of fluids.

The Relief Valve is available in a 5.5mm size and an 8.0mm for more flow.

A25 INSERT ORIFICES

IMH Orifices are economical, reliable,
highly accurate miniature restrictors.
These orifices are 100% flow tested to
ensure that every part is within ± 5% of its
nominal flow rate. Tighter flow tolerances
are available as specials. Tight flow toler-
ances are only possible if entrance and
exit conditions are closely controlled.This
provides far more accuracy than an orifice
specified by hole tolerance. An ordinary
hole held to a very tight hole tolerance
will not result in a tight flow tolerance.
IMH orifices are so consistent because they are produced in high volume by automated
processes. Installation is simple using the field proven controlled expansion principle which
provides retention up to 21 mPa (3,045 psid) and creates a leak tight seal. Constructed
entirely of stainless steel, these orifices will not change flow rate over time due either to
corrosion or erosion. Integral safety screens are incorporated where the orifice diameter
is 0.5mm (.020") or below.

Screened Screened
Forward Reverse

Integral
Safety Screen

Orifices come in three body diameters; 2,5mm, 5.5mm and 8.0mm to offer choices in size
and screen capacity. The 2.5mm model is the smallest self retained, screened restrictor
in the world, allowing designers to save space and weight, while reducing overall design
and assembly time.

All three sizes are available in gas and liquid versions. Gas orifices are tested on clean dry
nitrogen and liquid orifices on distilled water. Great care is taken to ensure the accuracy of
the automated test systems.To further increase accuracy, orifices are tested in the direction
of use. Simply refer to the diagram illustrating forward and reverse flow.
