Live-Loaded PTFE - V-Ring (standard)
For maintence free stem seal the Live-Loaded PTFE - V-Ring is both pressure energized and live - loaded by a 304 stinless steel pring to acutomatically compensate for packing wear. Maximum serice terature is 460°
(238°C). V-rings can be inverted for vacuum service. This packing configuration is available on Kombat, Intimidator, Boss and Doctor Actuators.
Split rings allow packing replacement without removal of actuator. Graphite impregnated PTFE provides 500°F (260°C) service temperature, better emory and sealing than pure PTFE rings, lowered stem hysteresis, and is ideal for fluids that contain suspended
particles. The PTFE/Graphite option is available on the Intimidate, Boss and Doctor Actuators.
High Temperature Laminated Graphite (optional)
Split rings allow packing replacement without removal of actuator. Precision die-cut laminated graphite rings provide a reliable, tight stem seal to operating temperatures of 800+ °F (426°C). The High Temperature Laminated Graphite is available on the
Intimidator, Boss and Doctor.
