Elastormer Seal Valvew (VR and VRD)

The VR valves are right angled general purpose UHV valves with a cycle usage minimum of 100,000 activations. The bonnet (top) seal of the valve is either welded (VR series) or demountable (VRD series). On the VRD series the whole movement mechanism can easily be removed and replaced.

    Gaskets & Accessories

    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

    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.
