ESD Block Features
1. One-piece ball /trunnions / stem assembly -
strong and reliable! 2. Ball axis of
rotation remains fixed due to bearing support 3.
Upstream sealing seats for bi-directional
shutoff - Permits testing of seats without
cycling valve - Uses live-loaded seals and fire
seals to allow for expansion and
contraction 4. Permits downstream seat and
upstream seat to seal in same direction (a
specification option) 5. Compatible with any
automation system 6. Takes a minimum of space,
½ the wt. of gate valves! 7. May be serviced
in-line (specification option)
Examples Boarding valves, battery limits,
etc.

Quick Opening (or Closing) Valve - Features

• 6-1500 full bore, 3000 psig
• One-piece ball / trunnions / stem assembly
• 2. Special soft seat design - stays in one
  piece after stroking!
• -and is bubble tight !
• 3. Actuator, mounting bracket, bonnet and valve
  body are
• dowel pinned together to maintain
  alignment
• 4. Specially designed actuator to handle end
  load impacts
• 5. Hydrogen atmosphere rated electrical
  accessories
• 6. Proven in service with many valves going
  through hundreds
• of cycles - still bubble tight !
• 7. Installed at Cape Canaveral Vandenberg AFB
• 8. No available "equal" to date 14 years!

21

• Additional Considerations for
• Lock hopper or Pigging Service
• Ball lip detail - must accommodate solids
• Ball seat coatings must be metallurgically
  bonded
• Seats to ball loading continuous to prevent
  particles from getting between sealing
  surfaces
• Sealing systems must accommodate rapid
  temperature
• changes
• Robust design - to assure high cycle life
• Note The valve cost is small compared to the
  cost of process downtime !

Trunnion-mounted split-body solids proof !
One-piece ball Trunnion mtd Upstream Sealing
Valve body cavity is isolated when full open or
full closed.
Basic Design Elements (Split body style)
42
Features
1. Live loading of seats and ball (sealing
arrangement) 2. Isolation of the valve body
cavity from solids (double seated-trunnion) 3.
Ball design that permits rotation within its own
geometry Trunnion Mounted - and permits
true double block bleed. 4. Designs that
accommodates radical temperature swings (up
down) 5. Smooth flow passages 6. Material
selections - both of coatings and substrates. 7.
Purges - if required for a particular
application 9. Solids Proofing to exclude
solids/particulates from critical areas these
may include sealant, solids barriers, purges and
bearing isolation.

73

• Valves - Suggested Specification Highlights
• Specify temperature range pressures.
• Specify ANSI B16.34, API, or Special Class
  rating.
• 3. Material choicescorrosion, high/low
  temperature, special trim materials expected,
  piping material, acceptable seat materials,
  coatings, weld overlays on sealing areas,
  specifications for plating, etc.
• 4. List suggested types and grades of seals as
  well as installation
• highlights, such as limiting cross-section
  sizes, backups, fire-
• seal requirements (live loaded for
  example.)
• 5. Testing In high pressure service, require
  the manufacturer to cycle the valve and prove
  operability. Suggested is testing to API 6A
  PSL 3 . Use water if in liquid service and
  nitrogen
• if in gas service - with the minimum
  holding periods and
• cycling requirements as outlined is this
  standard.
• Require material certificates for all components
  in the valve.
• Identify pipe schedules and end connections
  required.
• 9. Specify any additional options such as
  sealant injection,
• special painting, in-line serviceability,
  etc.
