same size as their equivalent check valves.
These valves come in forward and reverse
flow directions and incorporate a screen
of an appropriate filtration size for orifice
diameters below 0.5mm (0.020").

INSERT SHUTTLE VALVES

A63

The IMH Shuttle valve is a miniature, eco-
nomical and reliable solution to the problem
of hydraulic isolation in manifolds. This valve
features a compact, non-detented, selective
design that is ideal as a signal for auxiliary
functions, such as hydraulically released,
spring applied brakes as well as load sensing
applications.

The IMH Shuttle valve is available in two
sizes; a 5.5mm 2.5 GPM model and a 8.0mm
6 GPM version. These valves are the smallest
in their class, often one third the size of exist-
ing shuttle valves with comparable flow rates.

The all metal construction provides high reli-
ability, yet leakage is drip tight. Each valve is
100% factory tested for flow and leakage to
ensure consistent, long term performance.

This cartridge-style valve installs easily into a (1,200 lbs. force) and a maximum of 635 KgF
drilled hole, eliminating the need for threads (1,400 lbs. force). The ends of the expansion

A67 INSERT SAFETY SCREENS

IMH Screens are “last chance” safety
screens designed to protect critical
fluid control components against rogue
contamination. They are not intended
to serve as system filters. The screens
are constructed of stainless steel woven
wire mesh, bonded together using a
proprietary process that offers superior
integrity and life.
IMH Screens are available in Insert or
Cartridge styles. Insert Screens feature
an integral locking end, while Cartridge
Screens are designed to be retained by the customer, or for 5.5 and 8mm sizes, retained
by a separate locking end.
IMH Insert Style Screens use the proven Lee Insert Principle of controlled expansion
during installation to lock the screen in place.
A preinstalled expander pin is simply pressed flush with the screen body, expanding the
locking grooves into the wall of the installation hole to effect a seal and retain the part.
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.

IMH Cartridge Screens use proprietary high strength bonded
mesh to provide additional strength and integrity for applica-
tions where higher pressures could cause rupture due to the
effects of clogging, possibly with catastrophic consequences.
The unique design of the Lee Cartridge Screen is engineered
to prevent a rupture and instead allow a gradual reduction in
flow performance.

A79 LEE BETAPLUGS®

The Lee Company has supplied over
100 million Lee Plugs® to the aerospace
industry since 1948. Virtually every mili-
tary and commercial aircraft in flight today
contains Lee Plugs® in hydraulic, fuel, and
lube system manifolds. The IMH Division
based its commercial Lee Betaplug® de-
signs on the same reliable, field-proven
controlled expansion principle.

The Lee Betaplug is a pre-assembled,
one-piece, tapered expansion plug spe-
cifically engineered to seal fluid passages
in metal castings and plastic housings leak-tight, without the use of threads or sealants.
Controlled expansion during installation causes the lands and grooves on the O.D. of the plug
body to bite into the wall of the fluid passage, creating a leak-tight seal and assuring reten-
tion. The unique tapered design eliminates the need for tight manufacturing tolerances, and
allows the designer to minimize the wall thickness required around the plug, even for brittle
housing materials. Note: Betaplugs are not recommended for use above 275°F (135°C).

LEE BETAPLUG ADVANTAGE

KNOWN BOSS STRESS

Conventional, cylindrical shaped expansion
plugs require additional expansion for the
clearance between the plug O.D. and the
installation hole.

The matching tapers of the Betaplug and its
installation hole create a perfect fit, eliminating
the need for additional expansion. Since the
Betaplug’s expansion is precisely controlled
by the size of the tapered pin, the amount of
expansion and any resulting boss stress is
completely predictable.

The installation of Lee Betaplugs, whether performed manually or automatically, is very
easy and economical. First, the preassembled Betaplug is inserted into the tapered instal-
lation hole narrow end first. The pin is then driven into the plug using the recommended
Lee Company Installation/Staking Tool until the pin is below flush and the plug is staked.
The installation tool is designed to install the pin below flush while staking over the back
edge of the plug.

6000 SERIES BETAPLUG HOLE PREPARATION

The installation hole for a 6000 Series Lee D5 L3 D3
Betaplug has an included taper angle, Beta, MIN MIN MAX
of 4.3°, which matches the tapered outside 0.075 D4
diameter of the Betaplug. This included draft T.P. MM MIN D1 D2
angle of 4.3° is very easy to achieve with a core
pin in a die-cast or molded part or to machine 3.2 MAX
using a tapered tool.

A tolerance of ±0.3° on the taper angle of 4.3° 0.05

is specified to guarantee that the Betaplug’s L2 L1
rated performance is achieved. If the taper MIN

angles are out of tolerance, the plug will either

wedge first at the top or at the bottom, reducing

sealing burst pressure. Tapered reamers are available for each size Betaplug. See the tooling

table for applicable part numbers.

The Lee Company recommends that the Betaplug be installed below the surface of the hous-
ing to ensure maximum plug retention capability. The use of coatings or surface treatments
in the area of the installation hole where the Betaplug is to be installed is not recommended.

SHORT BETAPLUG HOLE PREPARATION

The Short Betaplug has been qualified to work
in generously toleranced installation holes.
The taper of the hole can range anywhere
from 4°-5°, giving the designer flexibility in
satisfying specific application requirements.
Tapered Reamers are available for each size
Short Betaplug. See the tooling table for ap-
plicable part numbers.

The Lee Company recommends that the
Short Betaplug be installed flush or below
the surface of the housing to ensure optimum
performance. The use of coatings or surface
treatments in the area of the installation hole
where the Short Betaplug is to be installed is
not recommended.

B1 IMH PRODUCTS FOR PLASTIC INSTALLATION

The Industrial Microhydraulics Group offers a line of products intended for installation into
plastic manifolds or fittings. A series of smoothly curved lands allow the part to be pressed
in while the plastic flows into the adjacent grooves. Some plastics with a lot of elongation,
such as Polypropylene, Nylon, Acetal, Polyethylene and PEEK, cold flow into the grooves
effecting retention and a seal.

Other plastics, such as acrylic and polycarbonate, are rigid and must be heat flowed into the
hole. The IMH Group can offer advice on the best methods of installation for each product
and plastic. We offer products already installed in plastic fittings, equipment to install our
products, as well as the service of installing them for you.

PLASTIC INSTALLATION SECTION II B2

Many of the insert products from Section I, TABLE OF CONTENTS
such as check valves, relief valves, orifices, Check and
restrictor check valves and safety screens, are Relief Valves............... B3 – B18
offered in the plastic installation configuration.
They contain many of the same features and Orifices........................ B19 – B26
offer the same benefits:

• Stainless Steel Construction
– Compatible with most fluids.

• Rugged, Durable Design
– Provides high reliability and long life.

• Low Leakage Valve Seats
– More efficient system performance.

• Highly Accurate Orifices
– Provides more consistent system
performance.

CHECK & RELIEF VALVES
B3 FOR PLASTIC

IMH Checks and Relief Valves for plastic
installation have the same internal design
as the inserts in Section I. A high quality
metal to metal seat provides low leakage
and highly repeatable cracking pressure.
Their all stainless steel design provides
compatibility with a wide range of fluids and
gases. Some models are available with a
ceramic ball as standard.These valves come
in three diameters (2.5, 5.5 and 8.0mm) with
corresponding flow capabilities. The 2.5mm
valve is the smallest cartridge style valve
available and is so small it fits in many com-
mon plastic fittings (see “Products in Plastic
Fittings” section, pages B39-B46).
