Fluids 

Thermodynamics and fluids are of essence to make 

industrial plants running and providing comfort to 

worldwide developed societies since more than a century 

ago. 

Water vaporizes on being heated thus becoming an 

excellent heating fluid transferring energy to diverse 

industrial processes and sterilization as well as generating 

hot water and heating. Water when subject to 

cooling processes provides Air Conditioned and comfort 

to Civil Works. 

Hydraulic oil make machine tools and plant equipment 

work trouble less inn diverse sectors such as lubrication, 

marine and mining amongst others. Thermal fluid 

is an excellent heat transfer fluid thanks to its powerful 

properties. Oil, gas and fuels are basic fossil source of 

energies required to keep the global industry in operation 

and are raw materials for the manufacture of 

plastics, chemicals and other manufactured products. 

Valves are essential devices to control fluids and the 

optimal performance of the industrial installations largely 

depends on the proper selection and application. 

Our company is highly experienced in the design, manufacture, 

selection and service of valves for the market 

sectors of HVAC, marine, processes, power and 

diverse industrial sectors. This corporate catalogue 

illustrates our products, services, brands and main 

references of our Company. Our team of specialists

22

Power Industry 

Power industry is possibly the most flourishing one in the today 

market sector thanks to the growing demand of energy from all 

developed and emerging countries. 

Natural resources are scarce and limited. They are drilled and 

pumped out, handled, stored and processed before being ready 

for consumers. These diverse processes require a large number 

of valves and special equipment to overcome hurdles such 

as severe pressure drops, high temperatures and highly loaded 

environments. 

Oil and gas are basic resources used in the transformation of 

fossil energies, the most demanded in the present world. Oil 

and gas need to be stored, transferred and refined for further 

distribution. 

Our range is comprehensive of valves and flow control products 

as in example: 

Linear and rotary valves check valves, control valves, severe 

control valves, safety relief valves, silencers and pressure regulators. 

All are recognized products from best in class manufacturers, all 

of them in possesion of the latest approvals as required in the 

power industry. 

Our own team of specialists is handling the latest tools and required 

experience to provide you a professional technical support, 

valve selection, sizing and recommendation in all projects 

and jobs you might wish to work together with us, 

24

Power Generation 

Electricity is generated throughout thermo 

electric plants and by use of fossil fuels or 

coal; these plants generate the so needed 

electricity to keep our society running. 

Other means to generate electricity, nuclear 

plants set apart, are combined cycle plants 

where a steam turbine helps to get the electricity 

to the grid. These plants are in need 

of severe control valves and by pass turbine 

valves as severe pressure drops, high temperatures 

and rugged constructions are innate 

to the plant design. 

Our specialized distribution programme is 

comprehensive of these valves, in example 

PARCOL, a well known international manufacturer 

of severe service control valves, 

including the avant-garde design of laberintic 

trim to withstand the severity of process 

conditions at these plants. 

Water shell boiler packages are also furnished 

with our one shop philosophy, in example: 

Pressure safety Valves ASME I, ASME 

VIII; high duty level indicators, desuperheaters, 

triple offset butterfly valves and so on.

Biofuels and Renewable Energies 

Bio 

Biofuels constitute a magnificent complement to the 

conventional energy resources. 

Biofuels plants generate Biodiesel or Bioethanol from 

recycle oils or natural ones such as seeds from sunflowers, 

wheat or other primary products from animal 

fats. Through a transesterization process, distillation 

and drying the Biofuels are obtained. 

All the way through these above processes a large diversity 

of valves are required, in example butterfly and 

ball valves as well as steam valves for the heating processes 

resulting from the glycerin development. Moreover 

the Biofuels storage tanks need to be furnished 

with blanketing valves and pressure / vacuum safety 

valves. 

Our CASHCO-VCI range is comprehensive of blanketing 

and pressure / vacuum valves; they are truly specialists 

on the vapor control in storage tanks. 

Electricity can also be generated in thermal solar power 

plants, the newest of many ways to generate electricity. 

The natural resource is unlimited – the sun rays 

– which directly focused on special parabolic through 

mirror panels heat thermal oil which is used to produce 

steam inj the bay of power area. Again a steam turbine 

generates the electricity which is sent out to the grid. 

26

Our Corporate Philosophy 

The present and future development of our Company 

cannot be understood without a deep involvement 

with our customers, the forge of a true partnership 

beyond the simple sale of our products. 

Our permanent challenge is completing “our integral 

Service Loop” as our daily customer relationship 

policy; this drives our corporate philosophy to 

meet and exceed our customers’ needs. 

Our team of professionals and associated partners 

who back us make easier the achievement of our 

challenges and target of future plan expansions. 

We are valve specialists who are eager to work on 

our customer’s side, transferring our knowledge 

and corporate honesty; should we are able to let 

these values transpire from this corporate catalogue, 

we would be ever happier to demonstrate 

them through our daily activity.
