What´s new:

• Reverse calculation of closing pressure drop Δpmax have been added for RV 1xx, RV/CV 2xx, RV/CV 3xx lineup
• For RV/CV 7xx lineup valves:
  - Completely redesigned functionality for determining the required actuator force
  - Added Flowserve pneumatic actuators for DN 200 and DN 250 nominal sizes
  - The range of Kv/Cv values has been expanded and the option of parabolic characteristic has been added for all throttling system designs
  - A "reverse labyrinth" throttling trim design has been added, enabling higher Kv values to be achieved in multi-stage throttling trims due to the reverse flow direction
• For RV/CV 3xx lineup valves, the option of "Garlock 1220-MS" packing has been added, allowing these valves to be used for molten salt media with temperature up to 400°C
• For RD 122/123 and RD 212/213 lineup pressure reducing valves, the option of impulse tubing with a G1/2 connection has been added
• Kvmin values have been added for RV 111, RV 122, and RV 113 lineup valves
