Higher Performance & Lower Cost

EASY AND QUICK

As shown in the above picture, MRV has its

own pneumatic actuator equipped inside

the valve body. The piston of the actuator

and the disc of the valve are directly

connected. When the piston moves by air

supply, the disc also moves back and forth

exactly in the same direction of the flow

path intuitively. This simple mechanical

structure and its operational principle allow

remarkably quick Open and Close by

pneumatic actuation.

PERFECT SEALING

Unlike the seating of those conventional

valves such as Butterfly, Ball, Plug, and so

on, there are No Scratch, No Push,

No Damage, and No Transformation

between the disc and the seat of MRV The

Axial Flow Valve since there is no hard

friction occurs to the seat as well as the

disc. This unique structural feature realizes

remarkably perfect sealing performance

with a much longer lifespan.

LESS FRICTION LESS WEAR

As explained in the above, such "friction" that occurs between the disc and the seat of those conventional rotary type valves such as Butterfly, Ball, Plug, and so on inevitably leads to

wear of its materials. Again, this wear leads to damage and transformation of the part

(disc and seat). Then, again, those damage and transformation eventually leads to leakage.

This is a very usual and typical problem and task that we need to work on for solution.

Of course, every valve has its own limited lifespan but our goal is to minimize maintenance,

cost, and headache while using and operating the valve. MRV is the final destination and

resolution for the ultimate flow control in the industrial environment.

SPACE SAVING UP TO 40% - 60%

MRV The Axial Flow Valve allows space saving in the plant.

Upon the valve's actuation and operating type, MRV realizes remarkable reduction of space volume occasionally up to 60% or

more compared to those conventional rotary or linear type valves

such as Ball, Plug, Globe, and so on.

Not only space saving but also overall efficiency can be maximized

since this space volume reduction inevitably leads to saving various

products and materials such as pipes, additional parts, and so on.

Of course, it all means 'cost saving' in the long run as well.

MARINE APPLICATION

DBB - DOUBLE BLOCK AND BLEED VALVE

OIL&GAS / MARINE APPLICATION

It provides fast response within 0.1 to 1 sec.

Also, as it provides stable operation in

severe condition that is very hard to open

and close the valve due to high pressure

and high differential pressure (up to 500 bar),

it is remarkably useful for shipbuilding,

offshore plant, and severe service.

It is operated by its own built-in pneumatic

actuator which means no need a separate

actuator to be assembled. Therefore, its

weight and volume can be reduced by half

or more. It is easy to install MRV in such space-limited plant environment and it leads

to less maintenance and cost.

The conventional plug valve quite often requires higher cost, complicated assembly,

heavier additional parts, and conservative

approach. Meanwhile, MRV is very potential

and innovative to replace this conventional

plug valve for Oil&Gas and Marine application

due to its own unique features as follows.

-. Remarkable space and cost savings

-. Lower energy consumption to operate

-. Fast response: quick open/close

-. Tight Shut-Off (Class VI)

MRV's advanced performance provides super-fast response within 0.1 to 1 sec and it is capable for severe condition that is very hard to open and close the valve due to high pressure and high differential pressure (up to 500 bar). MRV has taken the key role for success of Aerodynamic Test that has been accomplished by Korea Railroad Research Institute.
