Forged Steel Valves Overview
Forged Steel Valves Overview

Forged Steel Valves are classified by type, design variations and function. Forged Steel Valves can also be classified by material, end connections and pressure-temperature ratings.

The material classification generally refers to the valve body material such as bronze, iron, steel, stainless steel and plastic. The valve body may be produced with one material and the trim, may or may not be made of the same material.

Valve trim is exposed to flow media and may be made of a different material than the valve body. The trim is normally more corrosion resistant than the valve body, so that corrosion is less likely to occur at the valve seating area.

The earliest known types of Forged Steel Valves were plug Forged Steel Valves, which were first made of wood. During the industrial revolution, metallic gate and globe Forged Steel Valves, along with plug Forged Steel Valves, were widely used. It wasn’t until rubber compounding and plastic were developed that quarter-turn Forged Steel Valves were widely used in our industry.

The valve is actually stated by the NPS of the valve end connection. You should know that NPS is the abbreviation for Nominal Pipe Size. It refers to the named size of the pipe. The NPS of the valve end connections must always match the NPS of the line in which it is to be installed.

The valve material and the line size will determine the type of end connection. The end connections refer to the ends of the valve body, which are connected to pipe ends. There are a number of different types of end connections available on today’s Forged Steel Valves.

Each type of valve material has pressure and temperature limits. If the valve is exposed to pressures and temperatures exceeding the specified limits, the valve will not work properly.

When pressure or temperature limits have been exceeded there is danger of damaging or ruining the valve.

Forged Steel Valves are further described by specifications developed by certain governing groups. These groups have developed valve standards so that the valve supplied is able to perform its intended use. http://www.forgedvalves.com/
