Right-sizing pneumatic valves
as volume coefficient (Cv) or in liters per minute. All devices that conduct air resist flow to some degree, and pressure drop across a device will increase with flow. Less resistance means a smaller pressure drop. Note that any device, fitting, or run of tubing can affect the system flow rate

Dispelling myths of valve selection
captured in the conductor between the valve and actuator and often represents the majority of the air. Bear in mind that stroke time is directly proportional to the entire system exhaust volume and inversely proportional to To better grasp the vital roles that volume and play in a circuit's performance

Proportional valves eliminate design headaches
of closed-loop control systems. Proportional valves are a great alternative when an application requires more than on-off control, but not the high precision and expense of servovalves. As such, proportional valves are widely used in a multitude of applications, including the control of gas and air flow

Establishing a new method for determining valve flow coefficient
equation that preserved the standard Cv and introduced a second coefficient, Cg, which is determined from choked flow of air. Experimental data were included to demonstrate their success at correlating test data with a wide range of valve styles. Their equation was more accurate than Baumann's, and just

Did You Know that Valves are the Heart of Your System?
, union, sweat or flared type fittings. However, threaded is the most common. The larger valves use a flanged fitting. D) The maximum temperature and pressure are also considerations for steam and high temperature hot water systems. E) The next consideration is the actuator for your valve. Pneumatic
