Needle Valve Cv

Needle Valve Cv. In a general sense, the valve flow coefficient or c v is a number that represents a valve’s. Valve coefficient is usually denoted by cv.

Stainless Steel Integral Needle Valve, 0.09 Cv, 1/8 from products.swagelok.com

Standard valve fully opens in as little as 3 1/3 turns / quick turn needle valve (1 3/4 turns). The coefficient of flow (cv) is a formula which is used to determine a valves flows under various conditions and to select the correct valve for a flow application. Flow capacity of hoke® needle valves the cv factor is a flowcoefficient expressing the rate of flowin gallons per minute of 60° f (16° c) water with a pressure drop of 1 psi across the valve.

It is defined as the flow rate in us gallons per minute [gpm] of water at a temperature of 60 fahrenheit with a pressure drop across the valve of 1 psi. The coefficient of flow (cv) is a formula which is used to determine a valve’s flows under various conditions and to select the correct valve for a flow application. The very low internal volume and precision design make this valve ideal for use as a gas control valve in chromatographic systems.

Valve Coefficient Is Usually Denoted By Cv.

Standard Valve Fully Opens In As Little As 3 1/3 Turns / Quick Turn Needle Valve (1 3/4 Turns).

Stem is lifted off the seat more than 2x faster than conventional valves, which reduces throttling and therefore increases seat life. In a general sense, the valve flow coefficient or c v is a number that represents a valve’s. Ln series needle valves feature live loaded chevron packing below the stem for durability and reduce maintenance.
