The DN40 Control Valve, with a nominal diameter of 40mm (roughly 1-1/2 inch), is a crucial device used to regulate fluid flow by adjusting the size of the flow passage in response to signals from a controller. This precise adjustment allows for effective control over flow rate and, consequently, process variables such as pressure, temperature, and liquid level. Essential for maintaining optimal process conditions, the DN40 Control Valve offers reliable performance in managing various industrial processes, ensuring accurate and efficient control across a range of applications.
