Industrial Valves
• Valve types
 Butterfly
 Control
 Ball
 Check
• Mechanical motion
 Linear
 Rotary
 Oscillating
• Widely varying industries
 Water and chemical plants, paper mills,
refineries, and other industrial facilities
Slide 3
Valve Environments
• Temperatures
 -320 °F (-196 °C) to 450
°F (232 °C)
• Pressures
 0 to 750+ psi (52 bar)
• Control, isolate, and
regulate flow:
 Gases: air, natural, sour,
corrosive, steam, etc.
 Liquids: hydraulic fluids,
water, low and high
viscosity, etc.
 Solids: powder, slurry, etc.
Slide 4
The Valve Seal: A Critical Component
 In gas systems
 Valves require a consistent
performing seal to minimize
specified leakage rate at
operating temperatures and
pressures
 In liquid systems
 Valves need a reliable seal to
prevent leakage
 In systems encountering solids
 Valves must be durable and
contain a robust seal to prevent
obstruction
Slide 5
• Geometry
 Lips optimized for increased sealing contact area
 Locking ring to prevent shrinkage away from
hardware and/or to stabilize seal in hardware
 Back-up ring incorporated to prevent extrusion at
high pressures
• Jacket material
 Filled PTFE materials (polymer, polyimide),
UHMWPE materials
 Chemically compatible
 Wear resistant
 Extrusion resistant (UHMWPE)
 Temperature resistant
 Low friction (PTFE)
• Spring energizer (canted coil, helical ribbon,
close-coil spring)
 Chemically compatible
 Corrosion resistant
 Heavy force
 Customizable loads
Seal Design Considerations
Thin seal lips
increase flexibility
Spring energizer
promotes even
wear, better seal
performance
Locking ring
prevents shrinkage
Example:
Low Temperature
Sealing
Slide 6
Factors That Impact Seal Design
• Performance conditions
 Speed
 Pressure
 Media
 Life expectancy
 Torque capacity
 Temperature limits
• Hardware conditions
 Shaft diameter, material,
surface finish, surface
hardness, tolerances
 Shaft/bore misalignment

Summary & Recommendations
• To eliminate costly mistakes and
delays, consider sealing requirements
as part of overall valve design
• In early design stages, collaborate
with Bal Seal Engineering to:
 Get consultative engineering advice
 Review valve hardware design
 Estimate frictional outcome, if relevant
 Perform Finite Element Analysis
 Engage in collaborative seal design
discussion
 Custom design a seal that meet all your
system/application requirements
 Determine recommended test failure
criteria
 Produce high-quality seal prototypes
 Perform in-house testing
 Scale up to full production

  • 1. Sealing for Improved Industrial Valve Performance Karina Chavez Global Market Manager, Industrial Products Bal Seal Engineering www.balseal.com
  • 2. Slide 2 Industrial Valves • Valve types  Butterfly  Control  Ball  Check • Mechanical motion  Linear  Rotary  Oscillating • Widely varying industries  Water and chemical plants, paper mills, refineries, and other industrial facilities
  • 3. Slide 3 Valve Environments • Temperatures  -320 °F (-196 °C) to 450 °F (232 °C) • Pressures  0 to 750+ psi (52 bar) • Control, isolate, and regulate flow:  Gases: air, natural, sour, corrosive, steam, etc.  Liquids: hydraulic fluids, water, low and high viscosity, etc.  Solids: powder, slurry, etc.
  • 4. Slide 4 The Valve Seal: A Critical Component  In gas systems  Valves require a consistent performing seal to minimize specified leakage rate at operating temperatures and pressures  In liquid systems  Valves need a reliable seal to prevent leakage  In systems encountering solids  Valves must be durable and contain a robust seal to prevent obstruction
  • 5. Slide 5 • Geometry  Lips optimized for increased sealing contact area  Locking ring to prevent shrinkage away from hardware and/or to stabilize seal in hardware  Back-up ring incorporated to prevent extrusion at high pressures • Jacket material  Filled PTFE materials (polymer, polyimide), UHMWPE materials  Chemically compatible  Wear resistant  Extrusion resistant (UHMWPE)  Temperature resistant  Low friction (PTFE) • Spring energizer (canted coil, helical ribbon, close-coil spring)  Chemically compatible  Corrosion resistant  Heavy force  Customizable loads Seal Design Considerations Thin seal lips increase flexibility Spring energizer promotes even wear, better seal performance Locking ring prevents shrinkage Example: Low Temperature Sealing
  • 6. Slide 6 Factors That Impact Seal Design • Performance conditions  Speed  Pressure  Media  Life expectancy  Torque capacity  Temperature limits • Hardware conditions  Shaft diameter, material, surface finish, surface hardness, tolerances  Shaft/bore misalignment
  • 7. Slide 7 Impact of Surface Finish On Friction 391 765 1366 2488 4735 0 1000 2000 3000 4000 5000 2.0 4.0 8.0 16.0 32.0 FrictionalForce Grams Surface Finish Microinches RMS (Microinches Ra) Frictional Force vs. Surface Finish (1.8) (3.6) (7.2) (14.4) (28.8)

  • 13. Slide 13 Summary & Recommendations • To eliminate costly mistakes and delays, consider sealing requirements as part of overall valve design • In early design stages, collaborate with Bal Seal Engineering to:  Get consultative engineering advice  Review valve hardware design  Estimate frictional outcome, if relevant  Perform Finite Element Analysis  Engage in collaborative seal design discussion  Custom design a seal that meet all your system/application requirements  Determine recommended test failure criteria  Produce high-quality seal prototypes  Perform in-house testing  Scale up to full production
