Valve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. 阀门流量系数(Cv)是指液体或气体流过阀门的能力。 It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of ...
Valve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it.It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.”In simpler terms, the...
Valve flow coefficient, abbreviated as Cv (in the United States) or Kv (in Europe), is a numerical value used to quantify the flow capacity of a valve or other fluid control device. It is a parameter in fluid dynamics and is used to describe how well a valve can control the flow of...

The Flow Coefficient Parameterized Valve (TL) block models the flow characteristics of a valve using the flow coefficient as a means to relate the flow rate through the ports to the pressure drop across them.
At first, flow through the valve was simulated by the means of CFD method in ANSYS/Fluent software, assuming the fixed spool positions. Based on the results, flow coefficient values were determined. The results showed, that in the examined gap width range, the coefficient value is mainly ...
The valve is small, light weight, good processing technology, but the flow coefficient is slightly larger than the swing check valve 7-12 No-load running check valve valve, which is a special purpose check valve, is used for the outlet of the boiler feed pump to prevent the medium from ...
额定排量系数 (rated coefficient of discharge):排量系数与减低系数(取0.9)的乘积。 额定排量 (rated relieving capacity):实际排量中允许作为安全阀应用基准的那一部分。额定排量可以取以下三者之一: 1、实际排量乘以减低系数(取0.9); 2、理论排量乘以排量系数,再乘以减低系数(取0.9); ...
The main purpose of the present research is to determine the discharge coefficient of intake and exhaust valves in the engine cylinder head of a 406 cm. The experiment has been conducted using a flow bench model Superflow SF-1020. It is required to know such discharge coefficients, as a ...
