Pressure Monitoring in Pump Systems

Why do the inlet and outlet pressure of pumps need to be monitored? What issues may be encountered if they are not monitored?

Air compressors, irrigation systems, and heat exchangers all use pumps to push air or water through their systems. If the pressure in any of these systems is too high or too low, it could have serious consequences for the pump, the pipes, or the entire system. Most engineers choose pumps that operate 80-110% of their Best Efficiency Point (BEP), the point on the curve where the pump is most efficient. Pump performance will suffer if the pump is operating outside of the BEP, so it is important to monitor pressure to ensure you are getting the most out of your pumping system.

Advantages of V-Ball Valves

Introduction

Ball valves are designed to be used in a variety of applications and markets, but a V-port ball valve offers the added ability to be used as a control valve where necessary. The main differentiator is a contoured V-port in the ball, most commonly available with a 15°, 30°, 45°, 60°, or 90° angle, which produces an equal percentage flow characteristic for better control. V-ball valves are known to offer a variety of advantages in flow control applications, especially when compared to larger and more expensive control valves.
