DOWNSTREAMSEAT EXTERNALTHRUSTBEARINGThe Securaseal Type N was designed and developedfor the most severe services heavy industry has to offer. None are more severe than high pressure leaching by acid or oxygen used in the refining of nickel and gold ores. These services push every piece of equipment to the absolute limit requiring not only a sound and very robust design but also one that is on the cutting edge of technology.
Up To 6” (150 mm)

DESIGNFEATURES:

â—� Bi-directional sealing with preferred direction asshown ( ) .
â—� Oversized blowout-proof stem.
â—� Internal stem bushings absorb stem loadingmoments and provide guiding.

SEATING

â—� External thrust bearing significantly reducesvalve operation torque.
â—� Heavy duty precision machined actuator bracket ensures accurate stem alignment. .
â—� Advanced live-loaded stem packing arrangement standard
â—� Unique ball/seat spring-loading technology.
â—� Complete ball/seat set individually vacuumtested to verify sealing integrity. UPSTREAM SEATDOWNSTREAM SEAT
Above 6” (150 mm) â—� Advanced HVOF or Plasma Spray custom trimcoating technology with hardness in excess of 70 RC.

STEM & THRUST WASHER

â—� Superior ball/seat finish to 2–4 RMS.
â—� Fully guided stem, live-loaded packing gland and external thrust washer combine to prevent galling and reduce torque.
â—� Seat shroud eliminates particle migration intoseat recess.
â—� Locked-in downstream seat.
â—� Self energized body seal allows for servicesrequiring exotic materials or where severe pipe loads and/or thermal cycling is a concern.
â—� Designed to ASME B16.34. 17
