Control Valve Manufacturer

Body cavities, seat locations, stem guides, flange faces, threaded areas and other critical interfaces are machined to support alignment, sealing and assembly accuracy. Dimensional checks are performed at defined stages of production.

Plugs, cages, seats, stems, shafts and other internal components are matched to the approved trim design. Material, hardness, surface condition, guiding and movement are reviewed before and during valve assembly.

The valve is assembled with the specified pneumatic or electric actuator. Positioners, solenoid valves, air filter regulators, limit switches, handwheels and other accessories are mounted and connected according to the approved control and fail-safe requirements.

Valve travel, actuator stroke, bench set, signal response, opening direction and fail position are checked as applicable. The completed assembly is adjusted so the valve, actuator and positioner operate as one coordinated package.

After agreed pressure, leakage and functional checks are completed, the valve receives the specified surface preparation and coating. Openings are protected and the package is prepared for transport with the required tags and documents.
