How Power Generation Works in Singapore
Steam, Pressure and Utility Valves for Singapore Power Plants
Power generation in Singapore is built mainly around combined-cycle gas turbine plants, supported by waste-to-energy facilities, solar and imported power. These assets run close to continuous duty with limited outage windows, which places sustained load on steam, feedwater and cooling circuits. Valvewerkz supplies flow control for those circuits, selected for sealing integrity, thermal stability and predictable performance over long running periods.

Frequently Asked Questions
Common questions on steam, feedwater and cooling water valve selection for power generation plants in Singapore.
What types of valves are used in power plants in Singapore?
Power plants use gate valves and bellows seal globe valves on main steam and feedwater, ball valves on blowdown and drain service, butterfly valves on circulating and cooling water, check valves for reverse-flow protection, safety relief valves for boiler and pressure vessel protection, and steam traps throughout steam and condensate circuits. In Singapore’s predominantly combined-cycle fleet the same set applies across the heat recovery steam generator, steam turbine, condensate return and auxiliary cooling systems.
Why does thermal cycling matter for valve selection?
Thermal cycling repeatedly expands and contracts valve bodies, bonnets, stems and packing, which relaxes gland packing, loosens bonnet bolting and fatigues bellows. Combined-cycle plants that follow load cycle far harder than baseload plants, so cycle count belongs in the specification alongside pressure and temperature. It is also the main argument for bellows seal stems, live-loaded packing and specifying a fugitive-emission endurance class such as ISO 15848-1 CC2 or CC3.
Why are bellows seal globe valves used in power generation?
A bellows seal globe valve encloses the stem inside a welded metal bellows, so steam cannot escape along the stem even after thousands of thermal cycles have relaxed conventional gland packing. On high-temperature steam this removes the most common leak path in a plant, eliminates routine gland re-tightening during operation and avoids the energy loss and personnel hazard of live steam leaks, with gland packing retained behind the bellows as a secondary seal.
Which steam trap type belongs where in a power plant?
Thermodynamic disc traps are used on steam main drip legs and tracing because they are robust across a wide pressure range. Float and thermostatic traps are used on heat exchangers and process equipment where continuous discharge at near-steam temperature is needed. Inverted bucket traps suit turbine drains and superheated lines where waterhammer tolerance matters and a fail-open mode is preferred. Balanced-pressure thermostatic traps are used on tracing and drip legs where condensate sub-cooling is acceptable.
