Rotary Valve Repair

Disc & Seat Seal Renewal

Disc and seat surfaces damaged by wear or corrosion are restored on precision machining benches; tightness is tested and guaranteed to international standards (EN 12266 / API 598).

Actuator & Positioner Overhaul

Mechanical and electronic overhaul is carried out on pneumatic, hydraulic and electric actuators; positioner calibration, valve travel and open/close limits are set to factory values.

Stem Seal & Bearing Renewal

Failed stem seals and worn bearings are replaced with spare parts conforming to original manufacturer specifications; valve flow characteristics and torque values are verified.

Periodic Maintenance & Function Test

As part of routine maintenance, full open/close valve travel, torque measurement and tightness tests are performed; delivered with a maintenance report and certificate to ensure legal compliance.
