UHV Angle Valve, Manual, DN16CF / 0.75" ConFlat Del-Seal CF Port Flange, 312015

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 actuator, a poppet and a valve body. The actuator provides the power to position or transport the valve's poppet which is attached to the valve's body via a circular bonnet flange. The poppet closes or opens one of the valve's body ports. The valve body is a vacuum tight chamber that is screwed, flanged or welded into a larger vacuum vessel or system.

MDC stainless steel vacuum angle and inline valves have been designed for maximum conductance and minimum size for easy installation. These valves are ideally suited for systems requiring high reliability and low outgassing. The valves' low outgassing characteristics can be attributed to a fusion welded 304 stainless steel body, welded AM-350 stainless steel nesting bellows as well as small crosssection elastomers and the elimination of blind internal cavities.

MDC angle and inline valves are offered in various sizes ranging from 0.25" (1/4") | 6.35mm to 10" | 254mm port diameters. Standard port mounts include:

• Del-Seal™ CF ConFlat metal seal flanges, recommended for ultra-high vacuum (UHV) service

• Ultra-high vacuum (UHV) Series
• Del-Seal CF ConFlat flange port connections
• Manual actuator / operation
• OFE copper metal and poppet Fluorocarbon-based fluoroelastomer (FKM / FPM) elastomer bonnet seals
• Welded bellows actuator seal
• Tungsten Inert Gas (TIG) welded internal body joints
• Electropolished interior and exterior surfaces
