Frequently Asked Questions

Most frequent questions and answers

What is a valve?

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

What are the different types of valves?

There are many types of valves, including gate valves, globe valves, check valves, ball valves, butterfly valves, and diaphragm valves.

How do valves work?

Valves work by controlling the flow of a fluid through a pipe or passageway. They typically consist of a body, a stem, and a disc or other component that is used to open, close, or partially obstruct the flow of fluid.

What are the common materials used in valves?

Common materials used in valves include brass, bronze, cast iron, steel, and plastic. The choice of material depends on the application and the type of fluid that will be flowing through the valve.

What is the function of a valve?

The function of a valve is to control the flow of a fluid through a pipe or passageway. This can be done by opening, closing, or partially obstructing the flow of fluid. Valves can also be used to regulate pressure or temperature, and to isolate sections of a piping system.

How do I know when to replace a valve?

Some signs that a valve may need to be replaced include leakage, difficulty turning the valve, corrosion, and wear on the valve’s moving parts. If you notice any of these issues, it’s best to have a professional inspect the valve to determine whether it needs to be replaced.

How do you calculate valve Cv?

Cv by definition is the number of gallons per minute (GPM) a valve will flow with a 1 psi pressure drop across the valve. For example, a valve with a Cv of 10 will flow 10 GPM with a 1 psi pressure drop. The formula used to select the valve Cv with the specified differential pressure is Cv=GPM/((SQ RT(∆P)).

What is Valve Assembly?

A valve assembly is a process of combining all parts and components of the valve to make it a product according to the specified technical premise.
