Abstract: A valve assembly for a clean-in-place operation includes a valve body with a valve seat and inner cavity. A shaft extends through the valve body and a stopper is connected to the shaft for movement between a normally closed position and an open position to permit cleaning fluid to enter and exit the inner cavity only through the valve. An actuator contacts the shaft for moving the stopper toward the open position. An air inlet extends into the inner cavity. A stop valve associated with the inlet prevents fluid from exiting through the inlet such that cleaning fluid only enters and exits the inner cavity through the valve seat A source of pressurized air opens the stop valve and causes drying air to enter the cavity and move the stopper toward the open position and supply the air to the processing system.

Abstract: A valve assembly configured for a clean-in-place operation for processing systems includes a valve body with a valve seat and inner cavity extending into the valve body. A shaft extends through the valve body and a stopper is connected to one end of the shaft for movement between a normally closed position wherein the stopper sealingly engages the valve seat and an open position wherein the stopper is spaced from the valve seat to permit cleaning fluid to enter and exit the inner cavity only through the valve. An actuator is connected to the valve body and includes a plunger adapted for contacting an opposite end of the shaft for moving the stopper toward the open position when activated. An air inlet extends through the valve body and into the inner cavity.
