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.

Metal Seated Ball Valves Offer Potential for Long Term Cost Savings

The majority of ball valves are provided with one of several elastomeric materials forming a soft seat between the trim, or ball, and the valve body. With the balance of the valve assembly in contact with the media likely to be metal (unless, of  course, it is a plastic valve), the soft seat, because of its properties and location, tends to experience wear and tear and be a common cause for repair or valve performance deterioration.

In fluid process control applications where the media conditions may not, at first glance, warrant the use of a metal seated valve, there may be long term returns to be gained from the added cost of metal seats. The factors that create wear and degradation of soft seats are generally better tolerated by metal seats. Process downtime or man-hours for repair have a cost, so avoiding or reducing the occurrences of repair or maintenance provide a return on the additional expenditure for a metal seated valve that can provide a longer service life.

Many commonly available ball valves are also available with metal seats as an option, or metal seated variants are offered as uniquely identified products. Whatever the case, consider hardening your valve selections with metal seated valves. There are instances where they are well suited to the application and will offer a return on the additional cost.
