A valve asked to work below its minimum flow requirement may hunt and fluctuate, causing pressure spikes downstream, which can lead to pipe bursts. Mike Lybarger There are many options and several conditions that need to be considered when purchasing a valve. The V-Ball control valve is a fairly recent innovation, enabling all the benefits of a 3 piece ball valve with ISO5211 actuator platforms to be used as a pneumatic control valve by replacing the traditional ball with a V ball (a ball with a V shaped bore as opposed to a circular bore) which creates a more linear flow. While the eightinch S106 body meets the Cv requirement, the continuous flow recommended is below what is required for this application. It is also important to understand that while choosing a valve with special features may cost more at initial purchase, advanced features may make the valve more cost effective over the long run with a longer service life, easier maintenance, and/or the need for fewer replacement parts. Flow starts when the differential is able to overcome the weight and spring, and this increase in differential increases the opening force. In this example the 10- inch 206 body is the best selection, as it meets the Cv requirement, as well as the application meets the continuous flow recommendation for this valve. Any position on the curve to the left of the ‘I" allows the valve to be used in a Intermittent operation, which is up to a maximum of 25ft/sec. Sign up for Flow Control Network eNewsletters. ...

Valves require pressure differential to work correctly. There are several ways to properly size a valve; manually using the Cv method, using performance curves, or using the tables in a manufacturer’s catalogue. Ultimately, in order to size a valve correctly one must understand what the valve is required to do, what the system parameters are, and then use this information to pick the valve that will do a proper job while keeping the economic considerations in mind. The ultimate goal is to identify the best valve for the job required at the most economical price. Valves are normally closed unless actuated. Total Valve Systems' engineered product division is ISO The interlock system functions ‘passively’ and relies on the as-built actuator mechanisms to establish and confirm the status of the equipment.
