Dyna-Flo 380 series high pressure large control valve

3", 4x3" and 8" sliding stem control valve for ASME Class 900 to 2500, cage guided, shutoff Class II to VI, for severe high pressure gas and liquid service.

The 380 series covers the highest pressure classes in the Dyna-Flo sliding stem range, up to ASME Class 2500, in 3”, 4x3” and 8” sizes. It is built for the letdown, injection and spray duties in refineries, gas plants and power stations where both the static pressure and the pressure drop are extreme, with anti-cavitation and low-noise cage trims.

Selection data we need

Medium and its properties, inlet and outlet pressure, flow rate at minimum, normal and maximum conditions, temperature, allowable noise level, required shutoff class, pipe size and rating, actuator air supply and control signal, and any fail position. We size the valve and actuator in Dyna-Flo’s FloSpec software.

Applications

  • High pressure gas injection and production
  • Feedwater and superheater spray
  • Hydrocracker and hydrotreater letdown
  • Test separators and chokes
