This group can be subdivided into two basic valve types; right angled all metal valves and the right angled elastomer sealed valves. The choice of materials is dependent on the bakeout temperature, operating environment, lifetime and pressure requirements.
The elastomer sealed valve uses the elastic properties of a range of elastomers such as Viton®, Chemraz® or PTFE, to make the seal.
The all metal valve uses the elastic deformation of a softer metal pad by a hard metal seat to make the seal.
Elastomer seal right angle valve capable of 10,000 activation cycles.
All metal seal right angle valve capable of 10,000 activation cycles.
