pneumatic flanged ball valve SS304 Q641F PN16 DN10-300
pneumatic ball valve,through 0-90 degrees rotation, to achieve the adjustment of the flow rate and switch function. No clearance friction between the valve seat and spherical surface, with excellent shear force and self-cleaning ability, especially suitable for fluid medium with fibers or with small particles.
