 Product Model: Q41F4, F46 

 Corrosion-resistant fluorine-V type ball valve Overview: 

 V type ball valve spool designed with the special shape of the V-notch with precise closure of physical properties and control functions for a variety of control applications, compact structure, small size, flow capacity. Applies to the control of the gas-liquid, solid granular media. Valve plug and seat there is no gap between the rotation and therefore have a lot of shear force and self-cleaning properties, especially suitable for containing the fiber or the suspension of small solid particles and solid E-granular control. This product can be widely used in the automatic control system of the industrial sector of the petroleum, chemical, papermaking, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection.
