Power Industry
Power plants rely on stable control of flow, pressure, temperature, and water level across steam, water, gas, and auxiliary systems. YSMETER helps project teams assess industrial control valve solutions against the actual operating duty, control objective, installation constraints, and maintenance expectations of each application.
Whether the project involves a new unit, an upgrade, or replacement equipment, valve selection should begin with process data. A valve that performs well in one part of a plant may not be appropriate for another duty with a different pressure differential, temperature range, medium condition, or fail-safe requirement.
Power-generation systems can include demanding conditions such as elevated temperatures, substantial pressure differentials, frequent operating cycles, fluctuating loads, and strict shutdown requirements. The appropriate valve design, actuator, trim, and sealing arrangement should be evaluated as a complete assembly rather than as isolated components.
Key factors to review include:
Steam and thermal utility lines require careful consideration of pressure, temperature, control range, leakage expectations, and operating cycles. Control and isolation valves can be evaluated for main and auxiliary steam services, heating systems, and other thermal duties according to the project design conditions.
Feedwater-related duties may involve substantial pressure differentials and a need for stable modulation. The valve configuration should be reviewed with the process conditions, expected flow range, and downstream equipment protection requirements in mind.
Cooling-water networks, circulating-water systems, and water-treatment auxiliaries may require reliable flow control and automated isolation. Water quality, suspended solids, corrosion exposure, pump operation, and accessibility for maintenance can all influence the final selection.
Condensate handling, drain lines, compressed air, service water, and other plant utilities each have their own operating profiles. Reviewing these services separately helps ensure that the valve configuration and actuation approach suit the actual duty instead of relying on a single plant-wide specification.
The following solutions provide useful starting points when reviewing power-generation applications. Final suitability must be confirmed against project-specific process data.
Where pressure differential can affect control stability, a pressure-balanced configuration may be considered during the engineering review. It can be relevant to duties that require accurate modulation while conditions vary during operation.
For liquid services with a large pressure drop or cavitation risk, a cage-guided design may be evaluated as part of the overall flow-control strategy. The medium, differential pressure, flow range, and operating cycle should be confirmed before selection.
For severe pressure duties, a purpose-designed high-pressure control valve can help the project team assess appropriate trim, actuation, and sealing arrangements. This is particularly important where process forces and operating conditions create more demanding service requirements.

Provide the medium, normal and maximum pressure and temperature, line size, required control or shutoff function, expected flow range, pressure differential, actuator requirements, and any project-specific standards or documentation needs.
Not necessarily. Steam, feedwater, cooling water, condensate, and auxiliary services can have very different operating conditions. Each duty should be reviewed against its own process and maintenance requirements.
The actuator must provide the required thrust or torque, response time, control signal compatibility, and fail position for the duty. Available instrument air or electrical power, control-system integration, and environmental conditions should also be considered.
