Major factors making Big Blow™ your first choice: |
|
|
 |
Excellent performance with an absolute minimum of maintenance. This valve is built
rugged enough to withstand almost any problem. The Big Blow™ is almost indestructible.
It has tremendous resistance to abrasion, corrosion, shock waves, system vibration,
and sudden changes in temperature. |
|
 |
|
|
|
|
|
The seats are not exposed. They are inset from the bore and cannot be directly hit
by the flow of live steam or the flow of media, not even in the partially open position
at the beginning of the blow. |
|
|
|
|
|
|
|
Even if the seats are worn or destroyed, little leakage can flow through the valve
due to the small clearance between the blade and side plates. There is no danger
of dewatering. |
|
|
|
|
|
A simple locking mechanism is available to mechanically block the valve in the closed
position. The lock prevents the valve from being actuated unless unlocked by the
person in charge. The Big Blow™ is considered as safe as the installation of a blank |
|
|
|
|
|
Built in safety factors allow maintenance work behind the valve when the LC locking
device is engaged. The blade position is always visible even from a distance. Two
inches of stainless steel in a 10" Big Blow™ block the port, and cannot be blown
to the open position. Only one Big Blow™ valve per digester is required. |
