As a leading US manufacturer Bray International understands the demands required in pulp & paper mills today; long runs, uninterrupted service and production that goes on as scheduled without the need of costly valve failures that could shut downthe process. That is exactly what you get from Bray, soundly engineered valves with proven performance and reliability.
The pulp and paper processes are categorized as hazardous, corrosive, high pressure or abrasive which include those using:
Gaseous or Liquid Chlorine
Concentrated Hydrogen Peroxide
Other Industry Chemicals
Valves suited for the purpose
Resilient Seated Butterfly Valves
In applications up to 250 psi for valves up to 12 inches and 150 psi for 14 inch and larger.
Temperatures up to 250 degrees F and pipeline velocities at or below 30 feet per second.
Bidirectional & Unidirectional
Knife Gate valves
Valves for sludged (RAS, soft, viscous), slurries (abrasive, erosive, corrosive), powders (fine, coarse, chunks), high temperature (1000 deg C+)
Bleach stock line
Brown stock washers & pump isolation
Blow tank outlet
Triple offset butterfly valves
Compared to gate, globe or ball valves of the same size and pressure class, Tri Lok provides space and weight savings while minimizing installation and maintenance costs.
Tri Lok is a premier isolation valve, well suited for operation in light vacuum to high-pressure applications. The standard, non-rubbing, metal-to-metal sealing system is inherently fire-safe. Applications requiring absolute zero leakage are ideally suited for triple offset technology.
