Product Description
TECHNICAL FEATURES
•The more compact design structure.
•The sealing configuration is 3CW-FB, Can also be used as 2CW-CW.
•The inner sealing adopts distributed flushing, which can evenly cool the friction surface.
•The inner sealing adopts a double balanced integral ring design, which can effectively reduce the impact of pressure fluctuations and is suitable for both arrangement 2 and arrangement 3.
•The outer sealing, combined with the Plan 52, provides additional suppression sealing effect, while the Plan 53A/53B/54 maximizes the suppression of high-risk fluid leakage into the atmosphere.
•Well perform under Arrangement 2 or Arrangement 3 operation, containment control or eliminate of process emissions.
•Equipped with Quench and Drain environmental ports.
•Adopting a fixed graphite throttle bushing.
•Used for API Plan 52/53A/53B/54/61/62.
