Ceramic Vacuum Break

Provide electrical insulation for water or ln2 cooling lines depending on break type rated for high and ultra high vacuum applications.

Ceramic vacuum break.

Cf flanged vacuum ceramic breaks. It can be formed via dry pressing injection or hot pressing. Our vacuum breaker valves are manufactured out of stainless steel 316 or 303 or exotic alloys titanium alloy 20 monel or hastelloy. From 3 4 to 1 1 2 id.

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. Metal ends to provide a means of attaching to a vacuum chamber. Vacuum isolators are used to provide an electrical break between the vacuum system and other external components. Liquid break is used to transmit coolant fluid to provide an electrical break in the transmission line.

Visit the online store for vacuum sealed ceramic metal and glass ceramic composites at ceramtec north america. The typical plating for. 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. Stra val designs and manufactures its own line of vacuum breaker valves.

Diameter can be up to 800 mm. Constructed with vacuum grade materials including 304 stainless steel weldable lips high purity alumina ceramic insulation and vacuum tube grade braze alloys. Glazed alumina metallized ceramic pipe for vacuum breaker. Traditionally to break a vacuum in a load lock chamber nitrogen gas was slowly introduced into the chamber in a slow vent.

They are also suitable for use with currents of over 1 000 a and voltages exceeding 100 kv. 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. Between 3kv to 40kv. However up to 8 diameter can be accommodated.

The vacuum sealed ceramic to metal and glass to ceramic components are designed for cryogenic applications and can withstand temperatures of up to 450 c with a leak rate of under 1x10 9 atm cc s helium. Metallized ceramic pipe is often made of 95 alumina or higher grade. Vacuum break and electrical isolator. Alumina ceramic is widely used as an insulator in vacuum devices such as switching and microwave tubes.

Cryogenic and vacuum breaks are not suitable for water service because of corrosion while water and vacuum breaks are not suitable for. If you are looking for high quality performing inline spring check valves you have come to the right place.
