Factory Precision Ultra-High Vacuum Angle Valve for Gas
The MD-CD-Jb16KF ultra-high vacuum flapper valve is designed for use in high-vacuum systems, providing reliable control over airflow. It is available in both pneumatic and manual operation modes. The pneumatic version uses electromagnetic switching to direct air flow and operate the cylinder, enabling smooth opening and closing of the valve. The manual variant allows for direct handle rotation, which drives the valve via a screw mechanism, making it ideal for applications where non-corrosive gases or air are the working medium.
This product is suitable for industrial environments and offers a service life of over 10 years. It operates under compressed gas pressures ranging from 0.4 to 0.7 MPa and can be powered by either AC 220V 50Hz (6W) or DC 24V (3W). The valve can be installed in any position, offering flexibility in system design.
The leakage rate is exceptionally low, at ≤1.3×10â»Â¹â° Pa·m³/s, ensuring minimal gas loss. The valve is constructed with a stainless steel body and utilizes welding bellows for a secure shaft seal. This design enhances durability and reliability, even under demanding conditions.
Key features include a modular and compact structure, lightweight build, and a long service life due to reduced mechanical wear. The internal welding of the valve body further ensures a low leakage rate, while the use of imported fluororubber and 316L welding bellows improves sealing performance.
The MD-CD-Jb16KF is manufactured in China and is packed in standard export wooden cases for safe transportation. The trademark is Minder, known for its quality and innovation in vacuum technology.
**Product Description**
The MD-CD-J type ultra-high vacuum flapper valve is an essential component in high-vacuum systems, used to regulate the flow of air and non-corrosive gases. Available in both pneumatic and manual versions, it offers flexible control options. The pneumatic model uses electromagnetic switching to control the direction of air flow, driving the cylinder to open or close the valve. The manual version relies on a rotating handle connected to a screw drive system, allowing for precise and controlled operation.
