Instrumentation Ball Valves

Introduction

Instrumentation Ball Valve are precision-engineered valves designed to provide reliable control over fluid or gas flow in instrumentation and process control systems. These valves utilize a quarter-turn mechanism with a ball-shaped closure device featuring a bore through its center. When the ball is rotated, the bore aligns with the flow path to allow fluid passage or rotates perpendicular to block it, ensuring quick and efficient shutoff or flow regulation.

Instrumentation ball valve are typically constructed from high-grade materials like stainless steel, ensuring durability and resistance to corrosion in challenging environments. They are available in various sizes and configurations to accommodate diverse industrial applications, with some models offering multi-port options for enhanced flexibility.
