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.

Common Valves Used in the Oil & Gas Industry

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 Valve Sizing

Hi-Flow™ Valve Application

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.

What is Wastewater, and How is it Treated?

Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it is collected in the sewer system and delivered to plants for treatment to make the water safe to be returned to the environment.
