Kamroo valve can offer all series of valves and customization. Pls don't hesitate to contact us with other valves. A stainless steel ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control the flow of liquids or gases through it. The ball has a hole or port through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. Stainless steel is often chosen as the material for ball valves due to its durability, corrosion resistance, and suitability for a wide range of applications, including industries such as oil and gas, chemical processing, water treatment, and food and beverage. Solid wedge or flexible wedge design for excellent sealing performance. OS&Y (Outside Screw and Yoke) design for easy identification of valve position and maintenance. Rising stem design provides visual indication of valve position. Bolted bonnet or pressure seal bonnet design for high-pressure applications. Locking devices for safety and security. Optional handwheel, gearbox, or electric actuator for manual or automated operation. Optional extended bonnet for cryogenic applications. Optional bellows seal for fugitive emissions control. A ball valve is a shut-off valve that allows, obstructs, and controls the flow of liquids, gases, and vapors in a piping system by rotating the ball having a bore inside the valve. The ball is mounted against two seats and has a shaft that connects it to the operating and control mechanism that rotates the ball. When the cross-section of the bore is perpendicular to the area of the flow, the fluid is not permitted to pass through the valve. The fluid flows through from the valve, and the fluid flow rate depends on the area of the bore exposed to the flow. item valve Application oil and gas,oil and gas industry,petrochemical, chemical processing, pharmaceuticals, food and beverage, water treatment, and more.
