KOSO VeCTor 500M/500D/500J control valve, multi-stage trim, 1–36 in, ANSI 150–4500

KOSO VeCTor is a range of control valves with a patented multi-stage trim for severe service: high temperature, high pressure drop, risk of cavitation and noise. Staged throttling reduces flow velocity and pressure drop at each stage, so the valve operates without cavitation erosion and with reduced noise on compressible and incompressible media.

The series covers three levels: 500J — up to Level 8, an economical entry into multi-stage control; 500M — up to Level 24, the main choice for most severe duties; 500D — up to Level 40, maximum protection at extreme pressure drop. Globe or Angle body, sizes 1–36 inches.

Long trim life reduces maintenance costs, and separate diffusers and silencers are often not needed in a typical layout. The valve is combined with KOSO 5200LA and 6300LA pneumatic actuators, 3500LB / 3600LB electric actuators and the REXA 3800LA electro-hydraulic actuator.
