DKV VALVE provides high quality globe valve products. Since 1981, the DKV team has been developing and supplying globe valves in China. We offer globe valves in stainless steel, cast iron, cast steel and other materials. Please contact us for more information.
A globe valve is a linear motion valve designed to regulate, start, or stop fluid flow in pipelines. It features a spherical body with a movable disc (or plug) and stationary ring seat. By rotating the handwheel, the disc elevates or lowers via the stem, allowing precise flow control.
At DKV VALVE, we understand the importance of safety valves in maintaining pipeline transportation. Our globe valves have excellent designs and CE, ISO, and TS certifications. When used efficiently, DKV provides quality assurance.
Selecting the right material for globe valves is critical for ensuring optimal performance, longevity, and safety in diverse applications. The choice depends on factors like operating temperature, media compatibility, environmental conditions, and pressure requirements. Common materials include stainless steel, cast iron, and cast steel. Below, we break down their temperature limits, ideal environments, compatible media, and unique properties to help you make informed decisions.
Temperature Range: -254°C to 649°C.
Environment: Corrosive or hygienic settings (e.g., chemical plants, food processing).
Media: Acids, alkalis, steam, water.
Features: Exceptional corrosion resistance, durability, and high strength. Ideal for extreme temperatures and sanitary applications.
Temperature Range: -29°C to 232°C.
Environment: Low-pressure systems (e.g., HVAC, water supply).
Media: Water, air, non-corrosive fluids.
Features: Cost-effective, good machinability, but prone to rust. Best for budget-friendly, low-stress applications.
Temperature Range: -29°C to 232°C.
Environment: Low-pressure systems (e.g., HVAC, water supply).
Media: Water, air, non-corrosive fluids.
Features: Cost-effective, good machinability, but prone to rust. Best for budget-friendly, low-stress applications.
Temperature Range: -268°C to 593°C.
Environment: High-pressure/temperature systems (e.g., oil & gas, power generation).
Media: Steam, oil, gas, aggressive fluids.
Features: Superior strength, thermal stability, and resistance to pressure surges.

Selecting the proper connection method for globe valves ensures system integrity, leak prevention, and operational efficiency. Here’s a breakdown of threaded, flanged, and welded connections, including their applications, pressure limits, and key characteristics:
Applications: Small-scale or low-pressure systems (e.g., residential plumbing, HVAC).
Pressure: Up to 300 psi.
Features: Compact, easy to install without welding, and cost-effective. Limited durability for frequent adjustments.
Applications: Industrial systems requiring frequent maintenance (e.g., oil refineries, water treatment).
Pressure: Up to 2500 psi.
Features: Bolt-and-gasket sealing, easy disassembly, and robust leak resistance. Higher space and cost requirements.
Applications: Permanent, high-pressure/temperature systems (e.g., power plants, chemical pipelines).
Pressure: Exceeds 2500 psi.
Features: Permanent, leak-tight joints with no disassembly options. Ideal for critical, vibration-prone environments. Requires skilled welding (e.g., butt-weld per ASME B16.25).
