PV series pneumatic V-type regulating valve
The OPUS pneumatic V-shaped control valve is a spool seat metal or metal and polytetrafluoroethylene (PTFE) with the rotating ball valve can be used to control the control valve, but also for the shut-off valve to use. With a V-shaped body, even in the case of small flow or high-viscosity media, but also in the entire range, to ensure the accuracy of the control. V-shaped gap between the valve seat when the valve closes, the wedge-shearing, and has self-cleaning function to prevent the ball core stuck.
