Stainless steel v type pneumatic ball valve with positioner

Product feature

Pneumatic V type flanged ball valve introduction Pneumatic V type ball valve is a spherical core channel is designed toa open “V” shape of the valve, with accurate flow characteristic and control function. Through 0-90 degrees rotation, to achieve the adjustment of the flow rate and switchfunction. No clearance friction between the pneumatic V type flanged ball valve seat and spherical surface, with excellent shear force and self-cleaning ability, especially suitable for fluid medium with fibers or withsmall particles.
