DETAILED VIEW INTO OUR SERVICES
We support plant performance through the maintenance, renewal and refurbishment of control and mechanical valves and associated equipment.
Our services are focused on improving plant availability, maintaining operational integrity and ensuring compliance with statutory and safety requirements, in line with OEM standards and spare parts.
In addition to valve refurbishment, we offer the following:
In-House Machining
CNC Ball valve Grinding machine
Oxygen Services
Hydrostatic Testing
In-House Machining
GP Control Valves & Engineering and GP Mechanical Valve Services utilise advanced in-house machining capabilities as a core part of their service offering.
These capabilities enable the precise restoration, repair and manufacture of critical components, allowing for the correction of wear, damage and dimensional deviations.
Through accurate machining processes, components are restored within acceptable tolerances in accordance with OEM (Original Equipment Manufacturer) standards, ensuring proper fit, sealing integrity and reliable performance in cases where OEM spare parts are unavailable.
CNC Ball Valve Grinding Machine
Furthermore, our facility is equipped with a CNC ball grinding machine specifically for ball valves, capable of accommodating ball sizes ranging from 3 inch to 10 inch. This enables the precision grinding and restoration of valve balls to exact OEM specifications.
This capability ensures optimal sealing performance and extends the life cycle of critical ball valve components.
This integrated approach not only reduces lead times and costs, but also ensures a high level of quality control, reliability and consistency—positioning GP Control Valves & Engineering and GP Mechanical Valve Services as trusted service providers for critical valve refurbishment and engineering support in line with OEM standards.
Hydrostatic Testing
We provide hydrostatic testing of standard valve bodies and butterfly valves ranging from ¼ inch up to 74 inches, covering a wide range of industrial applications. All testing is conducted in line with recognised industry standards, including API 598, API RP 576, and API 527, ensuring valve integrity and leak-tight performance.
Our testing procedures verify the structural integrity of valve bodies, seat tightness and overall performance under pressure, ensuring that each valve is fit for service. Testing is carried out using calibrated equipment and controlled processes to deliver accurate and reliable results.
Upon completion, detailed test reports and certification are issued, providing full traceability and confirmation that the valve meets the required performance and compliance standards.
Oxygen Services
We provide specialised oxygen cleaning services to ensure valves and associated equipment comply with oxygen service requirements. The removal of oils, grease and contaminants is critical to prevent fire and explosion risks in oxygen applications.
Our controlled cleaning process ensures all components are thoroughly cleaned, inspected and handled to prevent recontamination, in line with industry standards.
All equipment is prepared, protected and where required, packaged to maintain cleanliness. Upon completion, an oxygen service certificate is issued, confirming the equipment is suitable for oxygen service and installation.
