VALVE SOLUTIONS / POWER & INDUSTRIAL STEAM
Valve options for high-temperature, high-pressure, drain and blowdown service. Selected around your operating conditions—not a generic model list.
Understand the duty.
Verify the data.
Define the valve.
START WITH THE SERVICE
Different steam-system duties create different failure modes. Begin with what the line must do, then narrow down the valve design.
01 / APPLICATIONS
For steam and condensate systems where high differential pressure, erosion and frequent operation make valve selection especially demanding.
For high-temperature steam and water lines requiring isolation, start-up and shutdown operation, or protection against reverse flow.
For application-specific duties around boilers, turbines and industrial steam systems, reviewed against the actual process and documentation.
A CLEARER SELECTION PROCESS
A useful technical discussion connects the process conditions, the valve design and the evidence required for acceptance.
Define the medium, pressure, temperature, line size and what the valve needs to do.
If it is a replacement, compare the nameplate, drawing, dimensions, materials and interfaces.
Check the applicable product data, ratings, standards, deviations and documentation.
Only then define the model, actuation, scope of supply and commercial requirements.
BUILD THE SPECIFICATION
Even an incomplete brief is useful when it makes the unknowns visible. Start with what you know and mark the rest for confirmation.
Design / operating pressure and maximum ΔP
Design / operating temperature and cycles
Steam, condensate, water, solids or two-phase flow
Size, pressure class, face-to-face and end details
Isolation, check, throttling, frequency and actuation
Applicable standard, leakage, testing and documents
PRACTICAL ANSWERS
Straight answers to common selection and replacement questions for steam and severe-service applications.
03 / RESOURCES
Start with the medium, design and operating pressure, maximum differential pressure, temperature, line size, connection, materials and operating frequency. The maximum pressure drop is especially important because a valve selected only by line size and pressure class may not suit the actual duty.
Provide the nameplate, original model, general arrangement drawing, face-to-face dimension, end-connection details, body and trim materials, actuator interface and acceptance requirements. “Interchangeable” should be confirmed by a drawing and deviation review.
No. Pressure drop, temperature, two-phase flow, solids, operating frequency and maintenance conditions can lead to different valve and trim selections. A product name alone is not enough to confirm suitability.
Not automatically. Some severe-service globe valves are intended only for fully open or fully closed isolation, even if their internal design reduces erosion. Always confirm the permitted operating function in the manufacturer’s data sheet.
