Forged Steel Valves for the Toughest Applications

Forging steel produces material of greater overall strength and toughness for parts and assemblies subjected to higher levels of stress. Forging is basically accomplished by applying localized mechanical pressure across the base steel, eliminating internal voids and gas pockets, while producing a unique oriented grain structure in the metal that delivers increased fatigue resistance.

Higher pressure or temperature applications in fluid process control can benefit from, and sometimes may require, the use of forged steel valves. Their ruggedness and ability to hold up under tough conditions make forged steel valves a good choice for many uses throughout general industrial, oil and gas, and power generation installations.

Forged steel valves are available in a broad range of sizes, connection types, and port configurations. Crane, world class manufacturer of industrial valves, offers forged steel gate, globe, and check valves to provide options for flow direction, stop, and throttle control.

There are almost countless variants and configurations of industrial valves from which to choose. Share your fluid control requirements and challenges with an industrial valve expert, combining your own process knowledge and experience with their product application expertise to develop effective solutions.

High Performance Non-Slam Check Valve

Crane Duo-Chek dual plate check valve
Check valves are ubiquitous throughout fluid processing operations. These simple devices permit fluid flow in one direction only. While there are numerous design variants available in the marketplace, operation is very similar in all check valves. Fluid pressure and movement in the desired direction moves a plate, plug, ball, or other obstruction to a position that allows flow to pass. The plate or other obstruction has a design countervailing force applied to it by a spring, gravity, or some other means that will move the trim to the closed position. When pressure drop across the valve decreases below the design level, the trim will close. Fluid pressure exerted on the outlet side of the valve will maintain a closed position in the valve. In this manner, a check valve allows fluid to pass in one direction, but not in the reverse.

Beneficial features of a check valve would include some or all of the following:

  • Lightweight and compact design
  • Tight shutoff that meets any applicable standards
  • Low pressure drop when open
  • Operation that minimizes seal wear
  • Installation simplicity and flexibility
  • Easy to insulate
  • Low maintenance requirements
  • No slamming to the closed position
  • No valve chatter
  • Available in numerous configurations to meet wide range of applications

Wellhead Valves Meet Special Application Challenges

Wellhead in oil and gas industry with equipment and valves
Numerous valves are employed at oil and gas production site
Industrial valves are manufactured in a huge array of configurations to accommodate the specialized needs of a broad range of industrial process applications. The oil and gas industry is but one segment of many throughout the industrial sphere that presents its own set of application specific criteria.

Oil and gas production, essentially pulling raw material from the earth, has unique valve performance challenges. Extreme pressure and abrasive or erosive material are common elements of oil and gas production at the wellhead. The valves also need to tolerate the range of outdoor temperatures at the production site. Safe and reliable operation throughout these and a range of other conditions are part of the design criteria for these valves. Here are some of the specific valve variants and configurations applied in the oil and gas industry at the production wellhead.

  • Slab Gate Valve - Provides metal to metal seal and employs parallel gate and seal with a preloaded spring to assure positive upstream and downstream seal. Full port design allows for pigging.
  • Expanding Gate Valve - A parallel expanding gate seals positively against both seats, which are protected from the flow medium in the open and closed positions.
  • Mud Gate Valve - Designed to provide positive closure under rigorous field conditions with abrasive media. 
  • External Sleeve Adjustable Choke Valve - Designed to regulate production well flow and downstream pressure. Different trim configurations provide appropriate levels of control.
  • Needle Adjustable Choke Valve - Utilizes different trim arrangement than external sleeve type to provide good flow management, abrasion resistance, erosion resistance, and reliable service over a long life with low maintenance requirements.
  • Check Valve - Check valves of various types are utilized throughout practically all fluid flow operations, essentially anywhere that fluid is supposed to flow in only one direction. Oil and gas production presents some special conditions of abrasion, erosion, and pressure that call for special accommodation in design and materials of construction.
There are other specialty valves employed at or near the wellhead, but the key take away here is that oil and gas production generally cannot be accommodated by general purpose valves. I have included a document below that provides additional data and engineering detail for the valves touched upon in this article. Share your oil and gas production challenges with a valve specialist. The combination of your process and production experience with their product expertise will produce effective solutions.

Check Valve Incorporates Useful Features For Industrial Process Fluid Systems

A check valve allows fluid flow in one direction (forward) and prevents it in another. They are employed extensively in industrial and commercial piping systems to prevent the reverse flow of a fluid that would produce an undesirable effect. Numerous sizes and types are available to meet specific application challenges. Each check valve must be properly selected to accommodate the pressure, temperature, and flow characteristics of each system. Proper materials of construction must be selected to provide suitable service with the process media.

Check valves are commonly applied to protect pumps from any induced reverse flow in a system. They can also be found in combination with other valves, providing assurance that the process fluid flows only in one direction.

One manufacturer, Titan Flow Control, incorporates a number of features into a single unit to provide wide ranging application. Features of the check valve are detailed below, along with a data sheet with more technical information. You can always get the latest available product data and solid application assistance from the process control specialists at Mountain States Engineering. Combining your process knowledge with their product application expertise will yield a positive outcome.

Swing Check Valve Operation - The Basics

Check Valve Symbol
There are several types of industrial check valves such as piston, ball, diaphragm, wafer and swing. The following video introduces the viewer to the inner workings of the swing check valve.

According to Wikipedia, "Check valves are used in many fluid systems such as those in chemical and power plants, and in many other industrial processes.

Check valves are also often used when multiple gases are mixed into one gas stream. A check valve is installed on each of the individual gas streams to prevent mixing of the gases in the original source.
"

The swing check uses the directional flow to push open a swinging disk. As long as flow continues, the disk stays raised. But as flow stops, gravity allows the disk to re-seat itself and any reverse flow is prevented by the closed disk. As reverse flow pressure increases, the swing check valves seating increases as well.
