Power Generation
Power Generation Valve Solutions
Our power generation valve solutions help Eskom and other power stations improve uptime, protect steam systems, and reduce pump failures.
South Africa’s power generation industry operates under some of the most demanding service conditions—superheated steam, extreme pressure cycling, and corrosive condensate can all compromise plant reliability and safety if not properly controlled.
At major utilities like Eskom’s coal-fired power stations, valve failure is not an option. Turbine protection, steam isolation, and pump safeguarding are mission-critical. That’s why plants depend on high-integrity valve solutions that deliver tight shut-off, reliable flow control, and automatic pump protection across base-load and peaking operations.
At Valve & Automation, we supply valve and control technologies engineered for the unique challenges of power generation. Our products help plants reduce unplanned outages, extend equipment life, and run safely and efficiently under high-stress conditions.
HP Valves – High-Pressure Forged Valves
HP Valves are specifically designed for steam systems operating under extreme pressure and temperature. Manufactured from forged materials, these valves provide long-term durability in critical turbine and boiler circuits.
Ideal for main steam lines, turbine bypass, desuperheaters, and boiler feed systems, HP Valves offer outstanding resistance to thermal fatigue and pressure cycling—ensuring safe, consistent operation in base-load and peaking stations.
Key Applications:
- Superheated and saturated steam control
- Turbine bypass and venting
- Boiler feedwater systems
Key Benefits:
- Designed for long-term high-pressure/high-temperature service
- Forged construction for maximum reliability
- Supported locally for faster spares and service response
Zwick Tri-Con – Triple Offset Isolation Valve
The Zwick Tri-Con is a precision-engineered triple offset valve delivering zero-leakage steam isolation in critical power plant systems. Its metal-to-metal, cone-in-cone seating ensures reliable shut-off even during high-temperature cycling and thermal expansion.
Used extensively within Eskom, the Tri-Con helps improve plant safety, reduce valve changeouts, and simplify actuator sizing due to its low torque design.
Key Applications:
- Main and auxiliary steam isolation
- Condensate systems
- Emergency shut-down valves (ESDVs)
Key Benefits:
- Zero-leakage tight shut-off for steam and condensate isolation
- Frictionless seating extends service life
- Compact, lower-weight design for easier installation and maintenance
Schroeder SSV – Automatic Recirculation Valve
The Schroeder SSV protects centrifugal boiler feed pumps and condensate pumps by ensuring minimum flow conditions are always maintained—automatically, without external control systems.
Its integrated non-return valve and smart bypass function safeguard pumps during low-load conditions, reducing damage risk and improving pump life expectancy—especially important for load-cycling units.
Key Applications:
- Boiler feed pump protection
- Condensate pump safeguarding
- Minimum flow assurance in variable load conditions
Key Benefits:
- No external instrumentation needed—fully automatic
- Reduces cavitation and pump wear
- Compact and maintenance-free design
