JDV Control Valves’ Floating Type Steam Jacket Ball Valves are called the JBK/JBKM series
The JBK/JBKM range of Steam Jacket Ball Valves includes:

  • Soft Seat Steam Jacket Ball Valves
  • Metal Seat Steam Jacket Ball Valves

JBK/JBKN Series Ball Valves are designed to maintain fluid temperature during an operation to keep fluids at a lower viscosity to allow steady flow.

They are available with optional seat materials which makes them suitable for a wide range of applications and industries.

Features of the JBK/JBKM Series Floating Type Steam Jacket Ball Valves:

  • 1-PC Valve body to prevent leaking from the joint side
  • The Full jacket design maintains an even fluid temperature
  • Seats are available in soft-seat and metal-seat designs
  • Anti-Static design
  • Anti-blow out stem design (size 2-1/2” and above)
  • ISO 5211 mounting pad
  • Fire safe design
  • Flange to flange fully jacketed design

Applications of the JBK/JBKM Series Floating Type Steam Jacket Ball Valves:

  • Heating fluids to reduce viscosity to maintain steady flow
  • Cooling volatile fluids
