What is Cv value of control valve?

Valve Flow Coefficient (Cv) is the flow capability of a control valve at fully open conditions relative to the pressure drop across the valve. It is defined as the volume of water (GPM in the US) at 60°F that will flow through a fully open valve with a pressure differential of 1 psi across the valve.

How much does a 16 inch gate valve weight?

Valve – Gate, Wedge, ANSI Class 150-2500, CS, Weight (in)

What is the Cv value of water?

What is Cv value? The valve flow coefficient according to the JIS standard, represents the flow capacity in US gallons/minute of 60° F pure water when it is flowing through the valve with a pressure difference of 1 psi at the specified travel (operation range).

How do you calculate valve CV?

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)). If the specified ∆P is 4 psid and full flow is 10 GPM the calculated CV is 10/SQ RT of 4 = 5.

What is ball valve CV?

Ball Valves. The below CV values are used to give an indication of flow rates for ball valves. CV value is an imperial measure of flow in US gallons per minute of water at 60° fahrenheit with a pressure drop of 1 psi across the valve. This is used as a guide and is not a linear progression.

What is a valve coefficient?

Valve Coefficient. The Valve Coefficient (also known as Flow Coefficient) of a valve is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across the valve and the corresponding flow rate.
