I often get asked, how should one simplify the hydronic balancing process? Since system blueprints will specify exactly where to set the balancing valves on the hydronic system to achieve proportional flow, it may seem simple enough for an installing contractor to determine the pressure drop through each circuit; however, hydronic systems are rarely installed exactly as designed. Continue reading “Work Smarter, Not Harder. Hydronic Balancing Simplified.”
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.

Valves are a vital part of any piping system, which means that they play a key role in the oil and gas industry. They can be used to control flow rates, to isolate and protect equipment, and guide and direct the refining process of crude oil. In this post, we will discuss five common valves that are used in the industry and what Dwyer Instruments, Inc. has to offer. Continue reading “Common Valves Used in the Oil & Gas Industry”
Control valves are used to change process conditions such as flow, temperature, level, and pH. A complete control system would include a sensor, controller, positioner or current to pressure transducer, and control valve. Globe valves, such as the Dwyer Hi-Flow™ Series, are a common type of control valve. In the example shown, a Hi-Flow™ control valve is controlling temperature by varying the amount of steam or cold water added to the process. Continue reading “Control Valve Sizing”
