Major factors making use of Big Blow™ the first choice:

· Excellent performance with an absolute minimum of maintenance. This valve is built rugged enough to withstand almost any problem related to the batch pulp digesters.

· The Big Blow™ is nearly indestructible. It has tremendous resistance to abrasion, corrosion, shock waves, system vibration, and sudden changes in temperature.

· The wear areas are the PTFE seats and packing. They have a normal life of three years. Longer life is common.

· 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.

· Big Blow™ valves of 10" and 12" size use 12" air cylinders, which generate over 9,000 lbs., thrust at 80-psi air pressure. This assures that the valves will not stick or hang during actuation. Big Blow™ Valves have the capability to shear foreign matter between the blade and side plate.
