In the simplest of terms, vacuum gate valves are devices that regulate the flow of gases, fluids or materials through a structure or aperture by opening, closing or obstructing a port or passageway. Gate valve assemblies consist of three key components: an actuator, a carriage/gate and a valve...

It is worth noting that reliable vacuum valves were not commercially available until the late 1940s with the advent of O-ring elastomer seals. The elastomer O-ring was developed during WWII for use in aircraft hydraulic systems, and was soon thereafter adopted by the vacuum community as the...

Vacuum angle and inline valves are devices that regulate the flow of gases, fluids or materials through a structure or aperture by opening, closing or obstructing a port or passageway. Angle valve assemblies consist of an ActuatorPoppetValve Body The actuator provides the power to position...

MDC's next generation high and ultra-high vacuum stainless steel angle and inline valves have been engineered to meet today's demanding market for high cycle life and performance reliability while at the same time taking advantage of efficient designs plus a streamlined manufacturing processes...

Sorption roughing pumps or sorption pumps are used for pumping systems from atmospheric pressure to a pressure of approximately 10-2 Torr. They rely on the dispersion forces existing between a gas and a surface to bind gas molecules on chilled surfaces inside the pump. In other words, they...

Bourdon Gauge Deflection gauges measure true pressure via deflection of a bourdon tube, independent of the type of gas in a system. Bourdon tubes are constructed in either C-tube or helical coil geometries and of these two, helical Bourdon tubes provide the greatest sensitivity. MDC Bourdon...

The reliable sealing performance of MDC's Del-Seal™ CF flanges is a result of a unique seal design and geometry which "captures" a metal gasket material. When a flat OFE copper gasket is pressed between the conical sealing edges of two Del-Seal™ CF flanges, a lateral cold flow of the gasket...

Molecular Sieve Traps Molecular sieve traps containing type 13X synthetic zeolite effectively prevent oil backstreaming and trap water vapors at room temperature.Type 13X zeolite will adsorb molecules with critical diameters up to 10 angstrom. The sieve charge can be reactivated by baking out in...

Features Excellent vibrational absorption Ideal for high heat and cryogenics 7740 Pyrex® 321ss bellows material 304ss flange material 400CC maximum bakeout * Allows up to 50% expansion and 20% compression of bellows length

MDC Butterfly valves require only one-quarter turn rotation of the handle to go from fully open to the fully closed position. In the 1-1/3" Mini Del-Seal™ CF flange series, a spring loaded ball bearing becomes seated in an indent providing a positive mechanical stop. All other size valves...
