Electric Stainless Steel Flange High Vacuum Ball Valve Leak-Proof Design For Semiconductor Manufacturing

Vacuum ball valve electric stainless steel flange high vacuum

1. Description:

Use of 1/4 rotary pneumatic or electric actuator, smooth work, valve switch has electrical signal output, can be used by hand, electricity.

Not only simple structure, good sealing, but also small installation size, small driving torque, simple operation, easy to achieve fast opening and closing .

Can be used in high vacuum state, can also be used in low pressure system, to achieve the advantages of positive and negative pressure.

2.Specification:

3. Features:

• Smooth type: for valves with low pressure. Easy to process.
• Concave and convex type: the working pressure is higher, and the medium hard washer can be used.
• Mortise and groove type: gaskets with large plastic deformation can be used widely in corrosive media, and the sealing effect is better.
• Trapezoidal groove type: with oval metal ring as a washer, used for working pressure ≥64 kg/cm2 of valves, or high temperature valves.
• Lens type: The washer is a lens shape and is made of metal. For high pressure valves with working pressure ≥100 kg/cm2, or high temperature valves.
• O-ring type: This is a newer form of flange connection, which is developed with the emergence of various rubber O-rings, and it is more reliable than the general flat washer in sealing effect.
