Problem Description

Motorized control valve is intended to regulate any kinds of liquids, steam, gas or

vacuum streams. It can be used in energy industry, chemical industry,medicine, foodindustry etc.

Generally, a control valve comprises three primary components: a valve,(such as a ball valve,) a DC motor with multi-stage reducer and a controlcircuit (see control valves manufactured by companies such as Siemens,Johnson Controls, Sauter, Danfoss, Belimo, Joventa).

Current motorized control valves have significant limitation:

Large working time (duration of closed-open mode ranges from 30to 140 seconds ),

Low accuracy - resolution (1-5 angular degrees);

High response time (1-2 seconds); High cost ( $ 400 for a valve with resolution 1-5 ang. degrees;

$1000 for a valve with 0.2 - 1 ang. degree resolution).

What is needed in the market ?

Motorized Control Valves with high control accuracy andwith small response times for a new generation of power

systems:

Engines of internal combustion;

Turbojets;

Steam and gas generators; Nuclear reactors;

Various hydraulic systems;

Medicine micropumps;

Food dosators;

Thus, thermo-gas- hydraulic systems must be work in real time,with speed approaching that of electronic systems.

Targeted Market Segment

Such a valve will find use in all systems in the world, which contain tubes:

-steam heating;-water pipelines;-gas pipelines;-oil pipelines;-power reactors;-chemical reactors;

-power motors;-vacuum systems.

In addition to the broader industrial uses described above, the piezoelectric valveoffers significant commercial potential at an individual household level. As a results:

-illumination cut-off valve (at the present time control valve and cut-of valve work

separately complementing each other);-precise regulation of household water supply and household heat supply with a

noiseless, energy-efficient;-significant safety improvement on existing systems for regulating householdgas supply, by reducing the risk of spark and explosion.

Competition

Lileya can surpass the competition by expanding itsproduction, developing more advanced piezoelectricvalves and selling to the existing and growing newgeneration of power systems and householdmarketplaces.

Lileya has a very skilled engineering team made up of 10former weapons scientists from the former Soviet Unionnow working in Kiev, Ukraine. This core engineeringteam designs, develops and tests advanced

piezoelectric valves.

The design, production and testing all can be done at afraction of the cost of the competition.

Opportunities

Lileya is seeking a western investor or company alliance.

Lileya needs additional members of the management team who are able tolead the company to new markets in the US, Europe, Japan and elsewhere.

We are seeking a CEO, a Marketing VP and a Chairman of our Board ofDirectors.

We are seeking investments of $500,000 over 2 years based on a BusinessPlan that is being prepared.

The funds would be used to set up permanent company offices, design and

testing facilities, and to develop and implement marketing and distributionstrategies.

Over the next year manufacturing capabilities would be improved with moreadvanced production equipment for manufacture of higher quantities.
