High Pressure Control Valve

Jet Flow Technologies Valve Division

High Pressure Control Valve

High Pressure Control Valve is designed and developed for applications where the high pressure / drop liquid and high pressure / temperature gas/vapour to be handled. Our specially designed Velocity Control Trim, which is a multi turn / multi-stage velocity control trim, handles these  severe/critical applications  very effectively – eliminating cavitation & vibration, and reducing the noise to the acceptable levels.


  • Velocity Control Trim
  • ASME B16.34 design standard
  • Excellent flow control rangeability
  • Linear, equal % and modified linear inherent flow characteristics
  • Leakage rate up to Class VI (as per ANSI/FCI 70-2)
  • Quick Change Trim Design Option

End Connection Styles:

  • Flanged
  • Butt Weld
  • Socket Weld
  • Screwed

Actuator Options:
Spring return diaphragm type as standard, other actuators viz. Electrical, Electro-hydraulic etc as options.

Plug Options:

  • Unbalanced Metal/Metal
  • Unbalanced Soft seat
  • Direction of Flow:
  • Flowed over

Cv Values and Valve Dimensions - Each valve is designed separately based on the given process data, service conditions and pipe line size & schedule. Cv values and valve dimensions would depend on the required no. of turns/stages, flow characteristics & pressure rating, and decided upon case by case basis. Hence, Cv values are not given in this technical bulletin; they would be specified on the calculation sheet and technical specification sheet of each valve.
