This range of valves are of right angled configuration, with a good conductance. The CR series comes with two body types, fully welded CR series or demountable CRD series.
Both the CR and CRD valves can be shut off to a torque level or by aligning the indicator marks on the body and the top nut.
A separate operating handle is included with the valve. Rotatable flanges are used on both valve axis.
VACGEN All Metal Right Angle Valves provide 10,000 cycles between services. Only high grade 304L materials are used. Rigid mechanism provides a repeatable seal.

To make a leak tight UHV seal between two conflat flanges, a gasket is required. Our gaskets are manufactured from quality controlled precision sheet material.
Leak valves are used to very accurately control the flow of gas into a vacuum system from an external source. They utilise the basic sealing principle of the all metal angle valve - namely a softer metal pad forced against a harder metal seat.
