An ASTM A217 C5 Control Valve is designed for high-temperature refinery services and is made from a 5% chromium and 0.5% molybdenum alloy. This material offers excellent performance in demanding environments, such as those found in oil and gas, petroleum, and offshore and onshore oil drilling applications. A control valve, including those made from ASTM A217 C5, regulates fluid flow by adjusting the size of the flow passage based on signals from a controller. This functionality allows for precise control of flow rate, pressure, temperature, and liquid levels within a process.
