Zimmermann & JansenMain Advantages of the
Double Disc Through Conduit Gate ValveMain Advantages of the
Double Disc Through Conduit Gate Valve• Real double block and purge
performance within one valve bodydue to 2 independent discs.
• Active mechanical seatingforce due to centralsplit-wedge-ball arrangement.
• Corrosion and wear resistant hard facing overlay on the seats; noadjustment and replacement ofseats required.
• No deposits of solid particles in valve body due to goggle type valvegate guided between guide plates.
• All internals removable throughbonnets.
• The sealing surfaces are com-pletely covered in each gate end position. Depositing within the valve and on the seats is avoided.
• Open goggle plate part equipped with tube to provide throughway.
• Purge steam connections for continuous valve body and seatpurge.

Final Considerations – Advatages and BenefitsSafety - during deheading and unheading no personnel
are required on deck due to fully remote operation.
- Real double block and purge - two independent discs.
Reliability - well proven valve design used in other severeservices such as ethylene, FCCU, phosgene, etc.
Cost reduction - low maintenance cost
- cycle time reduction
