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.
