Cast Steel Flange Bellow Globe Valve in Accordance with DIN Standard
Product Features
Exceptional Sealing Performance: Adopts a dual-sealing design with bellows and packing. Even if the bellows fail, the packing effectively prevents leakage, ensuring zero leakage in pipelines conveying hazardous media such as flammable, explosive, or toxic substances, thus guaranteeing operational safety.
High Corrosion Resistance: Select from various corrosion-resistant materials (e.g., stainless steel, alloy steel) based on the working medium and temperature to resist corrosion effectively and extend valve service life.
Rational Structural Design: The cone-shaped valve disc creates a streamlined flow path between the sealing surface and medium for better sealing. The valve stem nut uses aluminum bronze, and large-diameter valves are equipped with thrust bearings to ensure flexible and effortless operation.
Wide Application Scope: Suitable for water, steam, oil, natural gas, and various corrosive media, meeting diverse requirements across industries such as petroleum, chemical, pharmaceutical, and power.
Multiple Operation Modes: Available in manual, pneumatic, and electric options for automation or remote control, adaptable to different working conditions and user needs.
Technical Specifications
Size Range: 1/2"~16" (DN15~DN400)
Pressure Rating: 150LB~1500LB (PN20~PN260)
Working Temperature: -30°C~350°C (materials can be selected to suit specific temperature requirements).
Design & Manufacturing Standards: DIN 3356
Pressure & Temperature Standards: DIN 3230
Flange Connection Standards: DIN 2543–2545, DIN 2501
Welding Standards: DIN 3239
Testing & Inspection Standards: DIN 3230
Material Selection
Valve Body: Cast steel (e.g., WCB, WC6, WC9) with high strength and mechanical properties to withstand high pressures and temperatures.
Bellows: Typically made of corrosion-resistant and high-temperature-resistant metals like stainless steel or Inconel, connected to the valve stem via automatic seam welding to form a robust barrier against leakage.
Valve Disc: Materials such as stainless steel or hard alloy can be chosen based on the medium and working conditions to ensure excellent sealing and wear resistance.
Valve Stem: Constructed from stainless steel or similar materials, offering sufficient strength and rigidity, with special treatments to enhance corrosion and fatigue resistance.
Packing: High-quality materials like flexible graphite provide reliable sealing between the valve stem and gland, featuring excellent resistance to high temperatures and corrosion.
Application Areas
This cast steel flange bellow globe valve is widely used in pipeline systems across industries including petroleum, chemical, natural gas, pharmaceuticals, power, and metallurgy. It controls media flow and pressure for pipeline opening, closing, and regulation—particularly suitable for applications requiring strict sealing, such as conveying hazardous media or operating in harsh environments (e.g., high temperature, high pressure).
Competitive Advantage:
On Samples Buyer bear the air fee, but this fee will be reduced from order directly
On After Sales Free replacement if there is any quality problem
On Delivery Never delay delivery time
On Materials Ensure material pure
