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.

Control Valve Trim Styles and Flow Characteristics

Hi-Flow™ Valve Cutaway

Hi-Flow™ Control Valves vary the flow in a system by throttling the valve plug in and out of the valve seat. The corresponding flow rate through the valve is based on the valve plug and seat type, which is part of the valve trim. Dwyer Instruments, Inc. offers several flow characteristics, needle plugs, and restricted trim options for the Hi-Flow™ Control Valve series.

There are two types of inherent flow characteristic trim styles available in the Hi-Flow™ product line: Linear and Equal percentage. Continue reading “Control Valve Trim Styles and Flow Characteristics”

Find What You Want In Less Clicks

The Dwyer Instruments, Inc. website was launched 21 years ago and was one of the first instrumentation e-commerce websites of its kind. Over the years as new products and features were added to the site, navigation became more complex for new users. Dwyer continually strives to improve the user experience by making platform updates and reducing the number of clicks it takes to find and order a desired product.  To that end, users will begin to see navigation updates on the W.E.
