GTEC Valve Services: Total Pressure Integrity
GTEC provides world-class testing, calibration, and certification for the “heart” of your piping system. Whether it is a precision control valve or a 42-inch mainline gate valve, GTEC ensures zero-leakage performance and operational safety.
Three Pillars of Valve Excellence
Manual Valve Testing (Isolation & Integrity)
We verify the mechanical seat integrity and shell strength of your manual isolation valves.
- Capabilities: Full hydrostatic and pneumatic seat/shell testing.
- Types: Gate, Globe, Ball, Butterfly, and Check Valves.
- Standards: API 598 and ASME B16.34 compliance.
Control Valve Testing (Precision & Response)
A valve is only as good as its response time. We test the harmony between the actuator, positioner, and the valve body.
- Capabilities: Functional stroking, bench-set verification, and signal-to-response calibration.
- Focus: Ensuring your control loops respond with sub-percent accuracy to your automation system.
Relief Valve Testing (The Final Shield)
Safety Relief Valves (SRVs) and Pressure Relief Valves (PRVs) must work the first time, every time.
- Capabilities: Set-pressure verification, cold differential test pressure (CDTP) calculations, and seat tightness testing.
- Safety: Rigorous verification to ensure the valve lifts at the exact limit to protect your plant and personnel.
GTEC Valve Shop Facilities
Our dedicated valve workshop is equipped with specialized European and international testing technology to ensure total accuracy for even the most massive units.
On-Site Capabilities
For fixed assets and “Live-Loop” environments, we bring our testing power directly to your facility, reducing logistics costs and downtime.
High-Pressure Mobile Manifold (Up to 20,000 PSI)
We mobilize advanced pressure-control systems to your site, allowing for high-intensity hydrostatic and pneumatic testing in the field.
Large-Bore Blind Flanges (Up to 42 Inch)
GTEC maintains a full inventory of high-pressure blind flanges. Our capability to seal and test Valves in sizes upto 42-inch on-site ensures we can support major pipeline and refinery shutdowns .
