Orientations, Normal and Reverse Acting
 
Normal acting is full clockwise when the process valve is closed and counterclockwise when the process valve is open. Reverse acting is full clockwise when the process valve is open and counterclockwise when the process valve is closed.
 
90° indicator dome assemblies are designed to accommodate any mounting arrangement and can be adjusted up to 9° off axis if needed. 45° indicator dome assemblies can only accommodate normal acting applications that are mounted parallel ±9°. Consult your local distributor or factory representative for 45° reverse acting or mounted perpendicular applications.
 
The image to the left shows a TopWorx™ unit mounted parallel to the process valve in the closed position. The green arrow at the top shows the “normal acting” direction of travel to open the valve. This is the standard orientation and unless other-wise specified, your unit will be factory set to operate in this fashion.
 
The image to the right shows a TopWorx™ mounted perpendicular to the process valve in the closed position. The green arrow at the top shows the “normal acting” direction of travel to open the valve.
 
 
Mounting
 
TopWorx™ has numerous mounting bracket kits, both rotary and linear, available to meet your specific application. Consult your local distributor or factory representative for ordering information. The illustration below shows a direct NAMUR mount on a quarter turn valve. Refer to your mounting kit documentation for specific mounting instructions.
 
Storage
 
Until conduit, conduit covers, and any applicable spool valve port connections are properly installed, the TopWorx™ unit will not support its IP/NEMA rating as the unit ships with temporary covers. Ensure that it is stored in a dry environment with a relative humidity range between 10%-95% and a temperature ranging from -40ºF (-40ºC) to 160ºF (71ºC). Once properly installed, the temperature range listed on the name-plate will supersede this storage temperature range.
 

 
 
Mounting Assembly
 
Installation Notes
 
1. Use caution not to allow undue axial (thrust) load on the shaft.  
 
2. Cycle the valve a couple of times prior to final tightening of the mounting kit hardware. This allows the shaft to self-center in the pinion slot, or coupler. Refer to the dimensions and materials section of this document for appropriate tightening torque. Please refer to the Proof Testing section for proper safety function set-up.
 
3. Always use sound mechanical practices when applying torque to any hardware or making pneumatic connections. Refer to the Integrated Pneumatic Control Valves section for detailed information.
 
4. This product comes shipped with conduit covers in an effort to protect the internal components from debris during shipment and handling. It is the responsibility of the receiving and/or installing personnel to provide appropriate permanent sealing devices to prevent the intrusion of debris or moisture when stored or installed outdoors.
 
5. It is the responsibility of the installer, or end user, to install this product in accordance with the National Electrical Code (NFPA 70) or any other national or regional code defining proper practices.
