Product Features
PTFE Lined Pneumatic V-Port Ball Valve (GAPQ640F) Product Feature.
1. The shear force between the ball and the metal seat type V incision, especially suitable for containing fiber and small solid particle, pulp and other medium.
2. Fully open flow capacity, small pressure loss, and the media will not deposit in the body cavity.
3. Using a spring-loaded movable seat structure , Preventing the occurrence of ball core and valve seat from jamming or other issues, reliable sealing and long service life.
4. The valve has the advantages of accurate regulation and reliable positioning function, approximately equal percentage flow characteristics, large adjustable range, the maximum adjustable ratio 100:1.
Nominal diameter DN, Rated flow coefficient Kv, Allowable pressure difference.
