The AB-QM pressure-independent control valve combines automatic flow control and proportional temperature control into one compact device. The valve is available with several different actuators ...

Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow path of existing severe-service valves dissipates the forces from ...

A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...
