Ceramic Vacuum Break

Stra val designs and manufactures its own line of vacuum breaker valves.

Ceramic vacuum break.

Constructed with vacuum grade materials including 304 stainless steel weldable lips high purity alumina ceramic insulation and vacuum tube grade braze alloys. Alumina ceramic is widely used as an insulator in vacuum devices such as switching and microwave tubes. However up to 8 diameter can be accommodated. Diameter can be up to 800 mm.

From 3 4 to 1 1 2 id. Metallized ceramic pipe is often made of 95 alumina or higher grade. They are also suitable for use with currents of over 1 000 a and voltages exceeding 100 kv. We are able to manufacture a diversity of different specification metallized ceramic pipe the max.

Visit the online store for vacuum sealed ceramic metal and glass ceramic composites at ceramtec north america. Ceramic break is an electrical insulator. Since it has high stability against thermal treatment and a low outgassing rate as well as high dielectric and mechanical strengths it is a suitable material for insulators with good vacuum performance. The typical plating for.

Between 3kv to 40kv. Traditionally to break a vacuum in a load lock chamber nitrogen gas was slowly introduced into the chamber in a slow vent. Glazed alumina metallized ceramic pipe for vacuum breaker. Cryogenic and vacuum breaks are not suitable for water service because of corrosion while water and vacuum breaks are not suitable for.

Cf flanged vacuum ceramic breaks. Metal ends to provide a means of attaching to a vacuum chamber. Provide electrical insulation for water or ln2 cooling lines depending on break type rated for high and ultra high vacuum applications. Developed in cooperation with tokyo electron the break filter uses the extremely fine pores of porous ceramic material to produce a gas flow control diffuser in breaking a vacuum by utilizing the pressure buffer effect.

The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties mechanical design and the intended operating environment. Cryogenic and in vacuum breaks consist of ceramic insulating tubes with metal tubes brazed to each end and welded to iso for high vacuum hv or cf flanges for uhv service. If you are looking for high quality performing inline spring check valves you have come to the right place. Liquid break is used to transmit coolant fluid to provide an electrical break in the transmission line.

Vacuum break and electrical isolator. Our vacuum breaker valves are manufactured out of stainless steel 316 or 303 or exotic alloys titanium alloy 20 monel or hastelloy.
