The Cashco Model SCV-30 * is a revolutionary, throttling, pneumatically actuated control valve. This 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 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.
