High pressure and high temperature valves are designed for demanding media. Typical services include steam, superheated steam, hot oil, process gas, chemical media, boiler feedwater, and other critical fluids. In these environments, the valve must maintain reliable shutoff or flow control. It also needs to withstand pressure load, thermal cycling, erosion, corrosion, and installation stress.
As a high temperature valve manufacturer and high pressure valve supplier, SDF provides severe-service valves for power station piping and heavy industrial systems. We integrate R&D, manufacturing, testing, technical support, and after-sales service. This helps customers select valves that match real operating conditions.

Valve selection depends on the required pipeline function. Some systems need tight isolation, while others require throttling, non-return protection, pressure control, quick shutoff, or compact installation.
SDF manufactures gate valves, globe valves, check valves, ball valves, butterfly valves, control valves, and cryogenic valves. Customers can compare each option by function, pressure class, size, material, connection type, actuation method, and service conditions.
| Valve Type | Typical Function | Common Severe-Service Applications |
|---|---|---|
| Gate valves | Full-open/full-close isolation | Main steam lines, boiler systems, high pressure isolation service |
| Globe valves | Shutoff and throttling | Steam, hot media regulation, process control points |
| Check valves | Backflow prevention | Pump discharge, boiler protection, turbine auxiliary systems |
| Ball valves | Quick shutoff | Gas service, pipeline isolation, high pressure process lines |
| Butterfly valves | Compact shutoff and flow control | Large-diameter pipelines, hot gas, utility and process systems |
| Control valves | Flow, pressure, or process regulation | Power generation, chemical processing, petrochemical units |
High pressure gate valves are commonly selected for isolation in steam lines, boiler systems, and power station piping. SDF’s severe-service options include API 600 gate valves, pressure seal gate valves, forged steel gate valves, knife gate valves, and main steam gate valves.
For high-temperature and high-pressure duty, gate valve design must consider body structure, bonnet sealing, seat performance, stem sealing, and media compatibility. Pressure seal gate valves are often used where bonnet sealing performance is a key requirement.
Globe valves and control valves are used where the process requires throttling, pressure adjustment, flow regulation, or stable control under hot media conditions. SDF supplies globe valves, Y type globe valves, bellow seal globe valves, pneumatic diaphragm control valves, electric control valves, and pneumatic control valves.
In elevated-temperature service, selection should consider flow characteristics, trim design, sealing structure, packing performance, temperature cycling, and actuation method. These factors help maintain reliable control in steam, hot oil, gas, and chemical processing systems.
Check valves protect pumps, boilers, turbines, and process lines by preventing reverse flow. SDF’s available types include swing check valves, pressure seal swing check valves, dual plate wafer check valves, and lift check valves.
For severe service, customers should review media velocity, pressure class, installation orientation, closing behavior, and potential pressure fluctuation. Properly selected high temperature check valves help improve system safety and reduce reverse-flow damage risk.
Ball valves and butterfly valves are often selected for quick shutoff, lower operating torque, compact structure, or large pipeline size. SDF manufactures 3-piece stainless steel ball valves, fully welded ball valves, trunnion mounted ball valves, semi-ball valves, wafer butterfly valves, lug butterfly valves, and high-temperature butt welded butterfly valves.
High pressure ball valves suit demanding pipeline isolation and gas service. High temperature butterfly valves can support compact installation and large-diameter flow handling. Final selection depends on pressure rating, temperature, media, leakage requirement, connection type, and actuation needs.
SDF’s valve specifications cover a wide operating envelope for demanding industrial projects. Our portfolio includes valves from 1.6 MPa to 80.0 MPa, Class 150–4500, DN10 to DN4000, and -196°C to 1100°C.
The correct severe service valve is not selected by pressure and temperature alone. Buyers should also evaluate media type, temperature cycling, corrosion conditions, flow rate, leakage requirements, installation orientation, material compatibility, and project standards.
| Selection Factor | Why It Matters | Examples to Confirm |
|---|---|---|
| Pressure rating | Determines body strength, bonnet design, and pressure-bearing suitability | Working pressure, design pressure, Class rating, MPa rating |
| Temperature range | Influences body material, trim, packing, seat design, and thermal expansion | Working temperature, design temperature, temperature cycling |
| Media | Affects corrosion resistance, sealing structure, and material selection | Steam, hot oil, gas, hydrocarbons, chemical media, water |
| Valve structure | Determines whether the valve is suitable for isolation, throttling, or non-return service | Gate, globe, check, ball, butterfly, control valve |
| Connection type | Impacts installation reliability and pipeline compatibility | Flanged, butt-weld, wafer, lug, or project-specific connection |
| Actuation | Supports manual, automated, or control operation requirements | Manual, electric, pneumatic, pneumatic diaphragm |
Depending on service conditions, designs may involve pressure seal bonnets, forged or cast bodies, high-temperature trim materials, extended bonnets, metal seating, butt-weld ends, or special packing structures. Our team can review operating data and recommend a suitable configuration for severe-service applications.
High pressure and high temperature valves are used where ordinary valves may not provide enough sealing performance, thermal resistance, or pressure-bearing reliability. Typical environments include steam, boiler feedwater, superheated steam, hot oil, high-pressure gas, petrochemical process lines, and high-temperature chemical media.
SDF’s specialization in power station valves and heavy industrial valve manufacturing supports mission-critical applications. We serve power generation, chemical processing, oil & gas, petrochemicals, metallurgy, nuclear energy, natural gas, pharmaceuticals, renewable energy, and marine/shipbuilding sectors.
