Features
Disc Position Indicator - Marking the upper shaft. Shaft acc. ISO 5211 - For all type of actuators. Blow out Proof Spindle (Circlip) - Avoid driving shaft can be displaced outwards. Bushing - Guarantees perfect alignment of the shaft, reducing the torque. “O” sealing ring. - Offering an additional safety factor to the shaft avoiding leakages and prevents any external contamination. High precision fit disc and shaft squares. Easy to dismantle and avoid looseness between shaft-disc. Spherical disc with polished edges Ensures low torque and extends life of elastomer seat. High warranty coating Epoxy powder coating, thickness up to 400 microns. Great elastomer thickness Gives long lasting resilience and prevents external. No leakage via the shafts due to Static lower shaft. Accurate dimensions between faces gives the seat a well balanced tightness and an identical torque in every valve.
