Product Description
pneumatic shut-down ball valve pneumatic On-off ball valve
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.
