Compare the model connection
The published B80, B125 and B150 entries show a 24:1 ratio and recommended butterfly valve DN values of 80, 125 and 150. Compare the connection opening and mounting dimensions as well as nominal valve size.
Specify the feedback requirement
Include the required open/closed indication, control-system input, electrical rating and wiring arrangement in your inquiry. Signal type, switch configuration and enclosure suitability must be confirmed for the supplied version; they are not established by the product photograph.
Confirm torque and operating limits
Send the valve operating torque and installation conditions for selection. The legacy torque entries do not state units, so request the applicable specification before approving a model. Confirm the limit adjustment and installation orientation on the assembly drawing.
Send a complete gearbox inquiry
Attach the valve mounting drawing, drive dimensions, preferred handwheel arrangement and quantity. See the QWL dual-drive manual gearbox for a different drive configuration, or contact us to review the XWL-R connection.
