Slade Valve Packing

3300C – Slade’s Cost Effective Pump and Valve Packing
Reinforcement:    Each yarn of graphite foil is reinforced with high strength structural carbon fiber
Temp:    Mild Oxidizers to 1800°F/1000°C (for high temperatures, e.g., over 1000°F/540°C, consult the factory)*
Pressures:    Valves to 1000 PSI/70 BAR (for higher pressures, consult factory)*
pH Range:    1-14


3300W:    Inconel wire reinforced for higher pressures: 5000 PSI/350 BAR

3300LC:    Low chloride, high purity for nuclear service

3300LS:    Low sulfur, high purity for nuclear service

3300G – Slade’s Best All Purpose Pump and Valve Packing
Reinforcement:    Corners and yarns of graphite foil reinforced with high strength structural carbon fiber
Temp:    Mild Oxidizers to 1800°F/1000°C (for high temperatures, e.g., over 1000°F/540°C, consult the factory)*
Pressures:    Valves to 5000 PSI/350 BAR without end-rings*
Pumps:    Flush-free in many services to 4800 FPM (1400 m/min)
pH Range:    1-14
Applications:    Chemicals, steam, hydrocarbons, etc.
Installation:    
Check clearances and dimensions
Best to use no more than 5 rings in stuffing box (use Slade spacer bushings to reduce rings)
Cut rings on the bias (45° angle), stagger joints
Compress each sealing ring at least 25% (especially the first ring). Do not compress spacer bushings.
Loosen gland to allow it to relax
Snug the gland bolts and start the pump

3300GLC:    Low chloride for nuclear service
3300GLS:    Low sulfur for nuclear service

3300W – Slade’s Best Valve Packing
Reinforcement:    Each yarn of graphite foil is reinforced with InconelTM Foil shrouded in high strength carbon fiber
Temp:    Mild oxidizers to 1800°F/1000°C (for high temperatures, e.g., over 1000°F/540°C, consult the factory)*
Pressures:    Up to 5,000 psi/345 psi*

3300CJ – Slade’s Anti-Extrusion Carbon Fiber Packing
Description:    Carbon jacketed 3300C
Pressures:    Valves to 1000 psi/ 70 bar (for higher pressures, consult factory)*
Application:    Used as anti-extrusion end ring

*As the operating temperature increases, the pressure limit of the packing decreases.

Advantages of 3300 Products

Applications

  • Pinch Valves
  • Diaphram Valves
  • Needle Valves
  • Plug Valves
  • Butterfly Valves
  • Ball Valves
  • Check Valves
  • Relief Valves

Fire Safe

  • Slade braided graphite foil is API Fire Test Certified
  • API 589 First Edition
  • API 607 Fourth Edition (modified by EXXON Specs)
  • Tested by Southwest Research Institute
  • Witnessed by 3 EXXON Engineers
  • Temperatures to 1800°F/1000°C
  • Tested at 5% of allowable standard
  • Performed under a grant from the American Petroleum Institute
  • Warning: Valves sealed with packings containing lubricants or blocking agents (PTFE) may cause secondary fires when exposed to the intense heat of a fire in another unit, which would cause packing shrinkage and leakage of flammable fluids causing a secondary fire.
  • SLADE Patented Packings: rated FIRE SAFE

Emission Safe

  • PERF Emission Standards
  • Contact Slade for documentation
  • EXXON-Emission Report:
    • Emission tests, performed at a leading petroleum company’s test facility in Florham Park, NJ (using PERF procedures and standards), show that Slade patented, reinforced braided graphite foil outperformed standard die-formed graphite sealing rings.
    • Slade reduced emissions by 74%.
  • Corpus Report:
    • A major Gulf Coast, USA refinery reports that 96% of the 325 valves packed with slade reported zero ppm emissions.  Most of these valves were packed in the field by inexperienced installers.
  • Cambridge Report:
    • A major USA West Coast refinery reports that after 5 years, 96% of the 282 field installed valves were at zero emissions and that the 3,000 psi hydrogen control valves never went over 9 ppm during the 5 year test. Most of these valves were packed in the field.
