1、 Overview of Pneumatic High Pressure Three way Ball Valve Products
The Q614/15N pneumatic high-pressure three-way ball valve produced by Shanghai Yuhu Company is divided into three connection methods: internal thread, external thread, welded type, and flange type. The pneumatic high-pressure three-way ball valve can adopt intelligent control and positioning, and is matched with an electrical valve positioner. It can control the operation by inputting 4-20mADC signals and 0.4-0.7MPa gas source, and achieve the adjustment of parameters such as pressure, flow rate, temperature, and liquid level. It is powered by compressed air, and the valve stem drives the valve core to rotate 90 degrees inside the valve body to achieve full open close action. Pneumatic high-pressure three-way ball valve has the advantages of compact structure, small volume, reliable operation, good sealing, easy maintenance, convenient installation, and strong adaptability. Pneumatic high-pressure ball valves are widely used in industrial automatic control systems such as petroleum, chemical, teaching equipment, light industry, high-pressure equipment, pharmaceuticals, natural gas, papermaking, etc., for remote centralized control or on-site control.
