Effective Check Valve Selection and Placement for Industrial Piping Systems

When planning a check valve installation, the primary goal is to achieve a valve and piping system that offers the longest service life at the lowest cost. Accomplishing this goal while also ensuring that the system operates effectively and efficiently requires several considerations.

To facilitate the selection process, here are some guidelines to assist check valve users with choosing and implementing the right valve.

Christmas Tree or Wellhead?

From time to time, we re-post well-received editorial from VALVEMagazine.com. The following article initially ran on Sept. 27, 2017.

In the complicated but vital industry of drawing oil and gas out of the earth and getting it to the surface, people often get confused about the difference between a Christmas tree assembly and a wellhead. Although the terms are used interchangeably, they are not the same piece of equipment. Each has valves and related equipment that help it control and guide the flow of this precious resource.

Managing Valve Repair on Short Turnarounds and Downtimes

Valves are integral components in most industrial processes' overall operating efficiency, especially those in power, chemical and paper plants. As a result, valve maintenance is crucial to an industrial facility's performance, safety and profitability. When a total replacement is required, it can disrupt operations, as well as be labor-intensive and expensive. A more effective alternative is on-site valve repair and modification that allows for shorter downtimes and lower expenses.

Gas and Liquid Valves for Medical Devices

Gas and liquid valves are used throughout the medical device industry, in major part due to their automated functions, along with their excellent reliability and long life. They are used to control the flow, direction and pressure of gases (oxygen, for example) or fluids (including reagents and other aggressive or non-aggressive media) being used by a device. Air and oxygen valves, as well as liquid “isolation” valves commonly used in medical and diagnostic devices must also meet stringent regulatory requirements to assure compliance with FDA, CFDA, MDR amongst other standards demanded in this field.

Standards for Actuator/Gearbox Flanges

“Many variations in valve and actuator dimensions and characteristics have come into play especially now that we have worldwide vendors,” said Paul Souza, training manager at AUMA Actuators in a presentation at the Valve Manufacturers Association Virtual Valve Forum in November 2020. Souza covered standards and good practice for flanges and drive couplings. This article reports on the flange considerations.
