Gosco Valves: Designs That Outperform.

A major manufacturer of lids for the food industry was developing a new lid in their Research & Development lab. The lab’s retort (pressure cooker) was using traditional control valves (rising stem globe) with a 3-15 psi signal. A problem arose when the control valves could not handle the retort’s pressure and temperature at the desired response time.

Gosco Valves was able to provide a solution that included our S-Class Vari-V Control Valve (with characterized V-ball) and a vane-style pneumatic actuator with modulating control. The 10˚ V ball resulted in tighter control parameters enhanced by the vane actuator and a 4-20 mA positioner.

As a result, greater accuracy was achieved by the retort to successfully develop the new lid. By using the characterized ball technology within our Vari-V, the R&D lab was able to use the existing retort pressure vessel, avoiding the expense of engineering and procuring a new, larger retort. This specific request goes to show the manufacturing/engineering capability of Gosco Valves being able to provide a quick and logical solution within such a short time frame.
