Maria Valve
1 / 5
Electric Actuated Wafer Type V Port Segment Control Ball Valve: This electric V-shaped regulating ball valve is a rotary ball valve with a core seat made of metal or metal to PTFE sealing and matching. It combines the best control characteristics of the ball valve and butterfly valve into one, and can be used as both a control regulating valve and a shut-off valve.
The shear force between the ball and the metal seat type V incision is especially suitable for containing fiber and small solid particles, pulp, and other medium.
Fully open flow capacity, small pressure loss, and the media will not deposit in the body cavity.
Using a spring-loaded movable seat structure, preventing the occurrence of ball core and valve seat from jamming, ensuring reliable sealing and long service life.
Features accurate regulation and reliable positioning, with approximately equal percentage flow characteristics and a maximum adjustable ratio of 100:1.
