The QSHV pneumatic V-port control valve produced by GEROYAL is a high-precision control valve with a right-angle rotary structure. When used in conjunction with a valve positioner, it enables proportional control. The valve core of the pneumatic V-port control valve is designed with a specially shaped V-notch, providing precise throttling characteristics and control functions. The pneumatic V-port ball valve is suitable for various control applications, offering advantages such as a compact structure, small size, and the ability to be installed closely and horizontally. It is suitable for controlling gases, liquids, and solid granular media. Due to the gap-free rotation between the valve core and the valve seat, it exhibits strong shear force and self-cleaning performance, making it particularly suitable for suspensions containing fibrous or fine solid particles, as well as for controlling solid granular materials. Therefore, the pneumatic V-port control valve and pneumatic V-port ball valve can be widely used in automation systems across industrial sectors such as petroleum, chemical, papermaking, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection.
