In the world of power generation and industrial turbines, turbine valves play a crucial role in regulating steam and gas flow, ensuring efficiency, and maintaining safety. At T & W Valve and Machine Company, we specialize in the expert repair and refurbishment of turbine valves, helping industries maximize performance and prevent costly downtime.

Comprehensive Turbine Valve Repair Services

Our turbine valve repair process follows a meticulous approach to restore turbine valves to optimal working conditions. With years of expertise, precision machining, and state-of-the-art facilities, we ensure that each valve we service meets the highest industry standards.

Step 1: Inspection and Diagnosis

A thorough inspection is the first step in identifying wear, corrosion, cracks, or leaks in turbine valves. We utilize:

• Visual Inspections to check for external damage and contamination.
• Non-Destructive Testing (NDT) methods such as ultrasonic testing, magnetic particle inspection (MPI), and dye penetrant testing (DPT) to detect internal defects.
• Operational Testing to evaluate valve movement, sealing efficiency, and actuation response.

Step 2: Precision Disassembly

Each valve is carefully removed, disassembled, and documented to ensure a precise reassembly. Components such as the valve body, bonnet, actuator, stem, seats, and seals are examined for any defects that require repair or replacement.

Step 3: Cleaning and Surface Preparation

Before any machining or refurbishing takes place, we clean the valve components using chemical cleaning or sandblasting techniques. This process removes corrosion, deposits, and contaminants, ensuring a smooth restoration process.

Step 4: Expert Component Repair and Replacement

Our team of skilled technicians repairs or replaces turbine valve components, including:

• Valve Seats & Discs – Lapped or re-machined for a perfect seal; replacement if necessary.
• Stems & Guides – Straightened or replaced to maintain alignment.
• Actuator Repair – Disassembled, cleaned, recalibrated, and fitted with new seals or diaphragms.
• Springs & Fasteners – Checked for fatigue and replaced if needed.
• Seals & Gaskets – Always replaced to ensure a leak-free valve.

Step 5: Precision Reassembly and Calibration

Once repairs are completed, the valve is carefully reassembled, ensuring all components are aligned and properly lubricated with high-temperature, turbine-grade lubricants. Adjustments are made to:

• Spring tension
• Stem travel
• Seat positioning

Step 6: Rigorous Testing and Validation

Each turbine valve undergoes strict quality control testing to guarantee performance:

1. Pressure Testing – Hydrostatic or pneumatic tests confirm valve integrity under operational conditions.
2. Functional Testing – Ensures smooth movement, proper actuator response, and overall control efficiency.
3. Seat Tightness Test – Verifies complete sealing to prevent steam leakage.

Step 7: Installation and Commissioning

After passing all testing requirements, the valve is reinstalled into the turbine system. We conduct final operational tests under live conditions to monitor pressure stability and ensure flawless operation.
