1. GENERAL DESCRIPTION

The item is a precision-engineered, heavy-duty mechanical mounting kit (hardware adaptation set) designed to rigidly couple and integrate an intelligent valve controller (positioner) onto a pneumatic fluid power actuator. The kit ensures perfect axial alignment and backlash-free motion transfer between the actuator's accessory drive and the positioner's feedback shaft.

2. SYSTEM COMPONENTS & INTERFACE COMPATIBILITY

• Actuator Side Interface: Engineered exclusively for Rotork CP Range heavy-duty scotch-yoke pneumatic actuators, specifically optimized for size CP/S-065 (Spring-Return configuration).

• Instrument Side Interface: Engineered to match the mechanical footprint and feedback dimensions of the Valmet (formerly Metso) Neles ND9000 series intelligent valve controllers.

• Manufacturer Part Number: H077723

3. MATERIALS OF CONSTRUCTION

• Mounting Bracket: High-strength, corrosion-resistant stainless steel (typically AISI 304 or 316) or heavy-gauge carbon steel with a protective industrial powder coating or zinc plating.

• Coupling / Drive Adaptor: Precision-machined stainless steel designed to eliminate mechanical hysteresis and slip.

• Fasteners: High-tensile stainless steel bolts, washers, and locking nuts to prevent loosening under industrial pipeline vibration.

4. DESIGN & PERFORMANCE CRITERIA

• Alignment: Strict concentricity tolerances to mitigate side-loading forces on the positioner input shaft.

• Compliance: Conforms to international industrial automation standards for valve accessory mounting interfaces (incorporating VDI/VDE 3845 / NAMUR recommendations where applicable to the specific actuator housing).

• Environment: Suitable for harsh chemical, oil, gas, and industrial process plants. Resists atmospheric corrosion, moisture ingress, and thermal cycling.
