Features and Benefits

Non-Contacting Design – does not use contact to create a seal, therefore has no wearing parts and lasts the lifetime of the equipment
Internal Chamber – pressurizes sealing medium and directs it to the throttle
Throttle – pressurizes and efficiently distributes the sealing medium evenly around the circumference of the shaft, creating a positive purge and accommodates radial run-out and axial movement simultaneously
Compact Design – 1.125 in. (28.58 mm) overall length (OAL) to fit within tight spaces
Multiple Flange Options – provides flexibility to fit unique rotary valves designs
