The performance of your turbine is only as good as the valves that control it. Turbine valves are essential for regulating steam or gas flow, ensuring safety, and optimizing operational efficiency. At T & W Valve and Machine Company, we specialize in precision turbine valve repair, providing dependable, expert service that helps keep your critical equipment running smoothly and safely.

The Heart of Turbine Control

Turbine valves perform several mission-critical roles in a turbine system. They control steam or gas flow into the turbine, manage load and speed, isolate the turbine during shutdowns, and serve as safety mechanisms during trip events. Over time, even the most robust valves suffer from wear and tear due to high temperatures, pressure, and continuous operation.

Common issues include:

• Valve seat erosion
• Stem or disc wear
• Corrosion or pitting
• Actuator misalignment
• Steam or oil leaks

When these components fail or degrade, the consequences can be severe—ranging from efficiency losses to catastrophic turbine damage. That’s why routine inspection and timely, expert repair is essential.

Comprehensive Turbine Valve Repair Services

At T & W Valve and Machine Company, we offer a full spectrum of turbine valve repair solutions, designed to restore your valves to OEM or better-than-original performance. Whether you operate a fossil, nuclear, or combined cycle power plant—or any industrial turbine application—our expert technicians have the tools and experience to get the job done right.

Here’s what our turbine valve repair process includes:

1. Detailed Inspection and Diagnostics

We begin with a thorough inspection, identifying wear, cracks, pitting, corrosion, and leakage. Using advanced measuring and diagnostic tools, we assess valve clearances, actuator functionality, and seal integrity to determine exactly what needs repair or replacement.

2. Disassembly and Documentation

Each valve is carefully disassembled, and all parts are labeled and photographed to ensure accurate reassembly. This detailed documentation also helps track historical wear patterns and provides clients with a clear repair record.

3. Precision Machining and Lapping

Using in-house machining capabilities, we restore worn valve seats, stems, and discs to factory specifications. Valve seats and sealing surfaces are lapped to ensure a leak-tight fit, reducing operational losses and improving valve longevity.

4. Seal and Component Replacement

All seals, gaskets, bushings, and worn components are replaced using high-quality, industry-approved materials. This step is critical to prevent future leaks and ensure long-term durability.

5. Reassembly and Calibration

The valve is reassembled with precise torque settings and clearances. Actuators and linkage systems are calibrated to meet exact operational parameters, including opening/closing speeds, lift, and pressure thresholds.

6. Final Testing and Verification

We conduct rigorous functional tests to ensure each repaired valve meets or exceeds industry standards. Testing includes pressure testing, flow verification, and operational simulation under load conditions.

Servicing All Major Turbine Valve Types

Our technicians are trained to repair and service all major types of turbine valves, including:

• Main Stop Valves (MSV) – Control the entry of steam into the turbine.
• Control Valves (CV) – Modulate steam or gas flow to match load demand.
• Intercept Valves (IV) – Shut off steam during overspeed or trip events.
• Reheat Stop Valves (RSV) – Manage reheat steam pathways for efficiency.
• Emergency Trip Valves (ETV) – Serve as a fail-safe to isolate steam flow instantly.

We work with leading OEM brands such as GE, Siemens, Alstom, Toshiba, and others, and can fabricate or source custom parts when necessary.
