V-SHAPED REGULATION BALL VALVE
A. V-SHAPED REGULATION BALL VALVE FEATURES
The structure with cylindrical spring-loaded compensatory metal valve seat possesses reliable seating performance. The spool will not be blocked or fallen off from the valve seat with long service life. There is shearing action between the V-shaped notch on the spoof and the metal valve seal, which is suitable especially for controlling the medium such as high viscosity, containing fibers, solid particles and serous laid etc. It is more superior to control paper pulp of paper industry. With big flow of the valve and small pressure loss, the medium will not deposit in the inner cavity of the valve, the valve not only possesses the Char C1eristic of approximate percentage flow big adjustable scope the maximum adjustable ration of 100:1, but also possesses the functions of accurate adjustment and reliable positioning.
This valve series can be disposed with multiple driving models.
