TANACO IN-LINE VALVES
This Hand Actuated IN-LINE VALVE is essentially a spring-operated plug valve with a positive closed and open position. In the closed position the locknut lever is 90° to the right of the handle, the collar under the locknut will be loose and the plug firmly seated with spring tension from the actuator. 
To change position of the valve during the product run, move the locknut lever 180° CLOCKWISE before turning the handle as this releases the spring tension on the plug. The collar under the locknut will have tightened. To reseat, move the locknut lever back COUNTER CLOCKWISE so it is again 90° to the right of the handle in a closed position. It is just as simple as that.
A food grade “O” ring seals the plug stem in the actuator. FDA approved silicon gasket seals are permanently molded into actuator and bottom cap. For easy visual inspection a quick release clamp permits immediate withdrawal of plug and actuator from the body.
The HAND OPERATED TANACO IN-LINE VALVE illustrated is durable, maintenance free and can be thoroughly cleaned-in-place without removal of plug from body. It is the most efficient of all manually operated sanitary valves.
The Air Actuated IN-LINE VALVE is similar to the Hand Operated except that the plug stem is remotely controlled with each movement of the piston in the air cylinder. Solenoids in the control panel open to introduce air into one side of the horizontal cylinder, pushing the piston forward to turn the valve plug 90° , then into the other side for piston return. 
The valve turns in one direction, clockwise. A pointer mounted on the plug stem clearly shows the position of the plug at all times. When used in aseptic systems, valves can be incorporated into the plant’s existing control panels. Single valves may also be operated remotely by a 4-way solenoid valve.
The valve lines can be cleaned and sterilized in the usual manner by plug rotation. An air line hooked up to the vertical piston cylinder on top can be used to lift the plug for thorough cleansing inside the valve body and ports.
Processors can install AIR ACTUATED IN-LINE VALVES in place of existing valves and connect the air lines to a control panel without changing basic operations or retraining personnel.
