This high-mount, double-offset wafer butterfly valve requires separate checks of the actuator interface and the pipeline connection. The high mounting platform does not establish a higher pressure rating or prove suitability for a particular service.
Mounting, torque and replacement checks
Confirm the stem end, mounting holes, coupling, bracket height, rotation and travel against the actuator drawing. Select the operating torque for the actual differential pressure, seat friction and operating frequency. For wafer installation, check flange standard and facing, installed length, pipe bore and full disc travel. Request the assembly drawing, materials list and agreed leakage-test conditions; a matching nominal size alone does not prove interchangeability.
Frequently asked questions
Can I reuse an actuator with the same bolt pattern?
Not on that basis alone. Check the stem connection, coupling, bracket, rotation, travel and torque requirements for the complete assembly.
Does a high platform mean a higher pressure class?
No. It describes the mounting arrangement. The valve pressure-temperature limits depend on the complete construction, materials and applicable rating documents.
What should I measure before replacing an existing valve?
Provide flange details, face-to-face space, pipe bore and disc clearance, together with actuator and maintenance space. Confirm these against the supplied drawing.
