We also manufacture throttling, rotary, and linear control high flow Model SCV-30 * are revolutionary, throttling, pneumatically actuated control high flow valves. The unique design provides a geometrically characterized plug for superior throttling dynamics, plus the unit’s ease of cleanability and maintenance meet the requirements of sanitary control valves. The design of these high flow valves incorporates a formed internal diaphragm that is bonded to a characterized metal plug. The diaphragm/body provides the smooth internal passages necessary for ease in cleaning and sanitizing. The plug head provides rigidity to the otherwise flexible diaphragm in the throttling zone where characterized control is desired. Cashco Model 520 are sliding stem, angle style, bellows sealed, pneumatically actuated control high flow valves designed to provide superior long-term performance and maximum corrosion resistance in pure chemical service. The design allows for all wetted internal parts to be machined from a solid block of isostatically compacted, virgin TFE, thus assuring maximum density and the lowest possible permeability. An additional design benefit is that the wall thickness integrity is assured as a result of the TFE body being internally machined after it is secured in a cast 304 SST body shell, thus preventing distortion problems related to the plastic stability of TFE. There is simply no better design or materials available when consideration is given to corrosion resistance and thermal stability.
