Von Scheven Ball Valve vS HD Series

The von Scheven ball valve vS HD series is a high-pressure pneumatic ball valve series launched by the German company von Scheven. It has the characteristics of high performance and high reliability. The following is a detailed introduction:

Product positioning: vS HD series ball valves belong to high-pressure pneumatic ball valves, such as the EHK1407 ball valve, designed with a pressure rating of PN2500, suitable for high-pressure fluid control systems.

Technical Specifications

Connection system: The interface adopts metric internal thread, with a size of M30x2, suitable for HP thread connection. The driver interface follows the DINISO5211F05 standard and corresponds to the size of the VKSW17 wrench.

Structural dimensions: The length can be customized according to the drawings. The shell is made of stainless steel 1.4542 (1Cr17Ni2) material, which has good corrosion resistance.

Pressure range: The working pressure range is 0-2500 bar, and the control pressure requirement is 6-10 bar.

Working temperature: The working temperature range is 0-90 ° C.

Sealing material: PEEK material is used for ball sealing, and NBR rubber is used for valve stem and housing sealing.

Core component technical solution

Mechanical structural components: The valve body and sphere are both made of stainless steel material, and the sphere has undergone special surface hardening treatment to enhance surface hardness. The drive system adopts SPF03-10 pneumatic actuator, which achieves rapid opening and closing of the valve through precise 90 ° rotation.

Sealing system design: The main seal adopts a sealing ring made of PEEK material, and an NBR sealing ring is used at the connection between the shell and the pipeline. The valve stem seal adopts a NBR material seal with a spring loaded structure to ensure zero leakage.

Working principle: When the control pressure is input at 6-10 bar, compressed air pushes the internal piston of the actuator, which is converted into the rotational motion of the valve stem through a gear or connecting rod mechanism, driving the ball to rotate and achieve valve opening; When the control pressure drops, the spring force acts on the valve stem, driving the ball to quickly reset and achieve sealing closure.

High pressure performance: von Scheven ball valve products include high-pressure ball valve types, and the VS-HD series may also have the ability to withstand high pressure, suitable for industrial scenarios that require high-pressure control.

Corrosion resistant materials: Considering the special requirements for valve materials in the chemical and natural gas industries, VS-HD series ball valves may use corrosion-resistant materials such as stainless steel to ensure long-term stable operation in harsh environments.

Reliable sealing: von Scheven ball valves are known for their excellent sealing performance, and the VS-HD series may also inherit this advantage by using sealing technology and materials to ensure zero leakage of the valve in the closed state.

Diversified connection methods: According to the product line of von Scheven ball valves, the VS-HD series may offer multiple connection methods, such as threaded connections, DIN flange connections, ANSI flange connections, etc., to meet the needs of different industrial scenarios.

Application scenarios: Suitable for high-pressure cleaning circuits in industrial water treatment, pressure control links in hydraulic test benches, and high-pressure water injection systems in petrochemical industries. At the same time, the ball valve has no copper alloy component, meets the hygiene standards for drinking water, and can also be used in food grade water treatment scenarios.
