German von Scheven ball valve

German von Scheven ball valve

　Von Scheven ball valves are produced by Rudolf von Scheven GmbH in Germany, which was founded in 1937 and has a 6000 square meter factory dedicated to the research and manufacturing of ball valves.

1、 Product Features

Guarantee: von Scheven ball valves have passed DINENISO/9001 certification, ensuring that the enterprise has an internationally recognized standardized process quality management system.

Diverse materials: Material selection includes carbon steel, stainless steel, etc., which can adapt to different working environments and medium requirements.

Excellent sealing performance: The product has excellent sealing performance, ensuring zero leakage in the closed state, suitable for occasions with strict sealing requirements.

Widely applicable: It can be used in multiple fields such as hydraulic, mining, chemical, mechanical, natural gas, etc., to meet the fluid control needs of different industries.

　　2、 Main products

Ball valves: including various types such as flange ball valves, low-pressure ball valves, high-pressure ball valves, stainless steel ball valves, etc.

Connector ball valve: Provides multiple connection methods, such as threaded connection, DIN flange connection, ANSI flange connection, etc., to meet the needs of different industrial scenarios.

Multi way ball valves: including two-way, three-way, and multi way ball valves, suitable for complex fluid control systems. working principle

Opening and closing control: By rotating the sphere 90 °, align the ball hole with the pipeline axis (fully open) or make it perpendicular (fully closed), achieving rapid opening and closing. The soft sealed valve seat can achieve zero leakage.

Sealing guarantee: The floating ball design utilizes medium pressure to press the ball tightly against the outlet valve seat, improving sealing reliability; The high-pressure series adopts a pre tensioned spring valve seat, which is suitable for high-pressure working conditions.

Structural adaptation: Block valve body reduces leakage points, anti spray valve stem+double O-ring enhances safety, and adapts to high-pressure/corrosive media.

IIItypical model

ESK type: 2-piece stainless steel ball valve, with a working pressure of up to 63 bar, suitable for DN8-100 specifications, and a working temperature range of -10 ° C to+200 ° C. The shell, sphere, etc. are made of stainless steel materials such as 1.4408, and the sealing element is made of PTFE, with excellent sealing performance.

HBI-C type: threaded ball valve, nominal diameter DN4 to DN25, nominal pressure PN500, made of carbon steel. There are two types of connecting threads: 06 series and 42 series, which comply with DINENISO228-1 standard and ANSI/ASMEB1.20.1 standard, respectively.

VS HD series: High pressure pneumatic ball valve, designed with a pressure rating of PN2500, suitable for high-pressure fluid control systems. The shell is made of stainless steel 1.4542 (1Cr17Ni2) material, which has good corrosion resistance.

　　4、 Application scenarios

Hydraulic system: von Scheven ball valves perform well in hydraulic systems, able to withstand high pressure and vibration, ensuring stable operation of the system.

Mining industry: In response to the sealing challenges in mining environments, von Scheven has developed specialized ball valves to ensure stable fluid transport during continuous operation of mining equipment.

In the field of chemical engineering, chemical media have special requirements for valve materials. von Scheven ball valves use corrosion-resistant materials to ensure long-term stable operation in harsh environments.

Natural gas industry: von Scheven ball valves have been widely used in natural gas transportation and distribution systems due to their excellent sealing performance and reliability.
